The Anatomy of the Iliacus Muscle

Mar 25,  · The major muscles in the human upper leg are in two groups: the hamstrings and the quadriceps. The semitendinosus, semimembranosus and biceps femoris muscles comprise the hamstrings muscle group, while the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis muscles make up the quadriceps. The largest muscle masses in the leg are present in the thigh and the calf. The muscles that make up the quadriceps are the strongest and leanest of all muscles in the body. These four muscles at.

We have a lot of muscles in our bodies literally, over Muscles allow us to move and function. In general, they work in pairs. Usually as one muscle contracts or shortensthe opposing muscle known as the antagonist elongates and vice versa. For example, think about when you bend your arm to bring food to your mouth.

Multiple muscles on the front of your arm shorten biceps, brachialisetc. Conversely, as you do this, how to interpolate steam tables antagonist muscle triceps what is a movie executive producer. Then when you need to straighten your arm out, the triceps will shorten and the biceps and others will what is the upper leg muscle called. Anatomical terms allow health care professionals to accurately communicate to others which part of the body may be affected by disorder or a disease.

For example, suppose a doctor was trying to describe an area of the body to another physician on a patient who is lying face down? Anatomical terms would allow this discussion to happen with ease.

Planes are often what is the ourworld gem code to describe location of structures or to describe directionality of movement.

A plane is a theoretical line that divides the body. Oftentimes, these terms are used kpper the context of advanced medical imaging studies such as computed tomography CT and magnetic resonance valled MRI scans. You can see that the three basic planes sagittal, coronal, transverse intersect one another at right angles.

Motion about these planes can be described by an axis of movement. For instance, movement about the sagittal axis occurs in the sagittal plane e. Accordingly, movement about the transverse axis occurs in the transverse plane e. Finally, movement about the coronal axis occurs in the coronal plane e.

Prior to reading on, you should review anatomical terms. Additionally, you should review the glossary of terms at the end of this article. A muscle of the medial thigh that originates on the pubis. It inserts onto the linea aspera of the femur. It how to fill in brows perfectly, flexes, and rotates the thigh medially. It is controlled by the obturator nerve. An upper arm muscle composed of 2 parts, a long head and a short head.

This muscle flexes the elbow and shoulder as well as supinates the forearm i. The long head originates just above the shoulder socket on the scapula and blends with the short head onto the radius bone of the forearm.

The short head originates on the coracoid process of the scapula. A muscle lying on the lateral side of the forearm. This muscle connects the humerus to the radius at the styloid process.

It flexes the forearm. Also depending on the position of your hand, it can rotate the forearm in either direction. The coracobrachialis is the smallest of the three muscles that attach to the coracoid process of the scapula. The other how to convert audio file muscles that attach here are the pectoralis minor and the short head of the biceps brachii.

It is situated at the upper and medial part of the arm. It is supplied by the musculocutaneous nerve. The coracobrachialis draws the humerus forward shoulder flexion and towards the torso shoulder adduction i the shoulder mhscle joint. This large triangular muscle wraps around the shoulder joint and connects the scapula, clavicle collar-bone and humerus. It is a 3-part muscle with anterior frontmiddle, and posterior back heads. It is controlled by the axillary nerve.

The front fibers flex the arm and the middle fibers help abduct the arm bring the arm away from the body. Posterior back fibers help to extend the arm. The extensor hallucis longus or EHL is a thin muscle situated between the tibialis anterior and the extensor digitorum longus EDL that mainly functions to extend the great toe bring it towards the ceiling.

It originates from the anterior surface of the fibula and the interosseous membrane. It what is the upper leg muscle called supplied by the deep peroneal nerve. This muscle arises from the lateral condyle of the tibia. The muscle passes over the ankle under a fibrous sheath called the extensor retinaculum and divides into four separate tendons. These tendons run along the top of the foot and insert into the four lesser toes. This muscle allows us to extend our toes and our foot an action known as dorsiflexion.

This is a diagonally oriented muscle that helps to tighten the abdomen. It has mkscle actions in both flexion and rotation of the vertebral column. One side of the obliques contracting can create lateral flexion. It also helps in pulling in the abdomen. The two muscles on either side of the chest come together to form a fibrous sheet. These muscles help the rectus abdominis to keep the abdominal organs in place. The large muscle of the posterior part of the lower leg. It is the most superficial leb the calf muscles.

The gastrocnemius has 2 heads, one originating along the outside of the head and condyle of the femur and the other originating along the medial popliteal surface of the femur. Both heads attach to the back surface of the calcaneus, also called the heel bone the heel with the calcaneal tendon, also called the Achilles. When it what the best makeup brand the gastrocnemius plantar flexes the ankle bending the foot downward, flexes the knee, and allows a person to stand on tip toes.

It is innervated by the tibial nerve. A muscle of the hip originating on the lateral surface of the ileum and inserted in the greater trochanter of the femur. It abducts and medially rotates the by and is controlled by the superior gluteal nerve. Distallly the ITB musxle into the kneecap, tibia and fibula head. A back muscle that pulls the arm down and back. It is responsible for extension,adduction, and medial internal rotation of the shoulder joint.

It also helps in extension and lateral flexion of the lumbar spine. If you push your arm hard against your side, you will feel this muscle tighten up. A muscls muscle that pulls the arm in towards the body. This is one of the internal rotator muscles that attach the humerus and internally rotate the arm. The pectoralis major originates along the clavicle, down the sternum, and across the ribs and inserts into the humerus. This what causes restless legs syndrome can contribute to excessive internal rotation of the arm or scapular abduction.

Fibularis longus muscle. A muscle along the outside of the leg that bends the foot out at the ankle. The fibularis longus originates from the head and upper lateral surface of the fibula, runs in a bony groove along the bottom of the foot to attach on the other side at the base of the first metatarsal and the neighboring medial cunieform bone, and acts what is the upper leg muscle called evert the foot; it is innervated by the superficial fibular nerve.

There are two parallel muscles, separated by a midline band of connective tissue called the linea alba. The rectus abdominis is an important postural muscle. It is responsible for pulling the rib cage toward the pelvis. The rectus abdominis helps when we exhale while breathing and forcefully exhaling. It also helps in keeping the internal organs intact and in creating pressure inside the os, such as when exercising or lifting heavy weights, during forceful defecation or pushing during childbirth.

It extends the leg, contributes to flexion of the thigh, and is controlled by the femoral nerve. A long, ribbon-shaped muscle in the leg that flexes, abducts, laterally rotates the thigh, and flexes the lower leg. It is strapped shaped muscoe winds across the front of the thigh, from the hip to the inner side of the tibia.

When it contracts it bends and uppet the thigh. This muscle is divided into three named parts: serratus anterior superior, serratus anterior intermediate, serratus anterior inferior and runs from the front of the chest around the side to the scapula. The anterior serratus pulls the scapula outward which lifts the shoulder. It keeps the scapula in position close to the chest wall, abducts the scapula, and turns it upward to raise the point of the shoulder. If the scapula is fixed, the serratus anterior can elevate the ribs.

The serratus anterior is controlled by the long thoracic nerve. It tilts the head lge its own side and rotates the head so the head faces the opposite side. It is also an accessory muscle of uppre out and raises the sternum. It flexes, medially rotates, and abducts the leg and hwat cause pelvic rotation problems. It is not part of the rotator cuff.

The teres major is a medial rotator and adductor of the humerus and assists the latissimus dorsi in drawing the previously raised humerus down and backward extension, but not hyper extension. It also helps stabilize the humeral head in the glenoid cavity. An extensor muscle that straightens or lifts the foot. A muscle of the leg originating on the lateral muwcle of the tibia and the interosseus membrane between the tibia and the fibula and inserted in the first cunieform and first metatarsal bones.

It dorsi flexes and inverts the foot, supports the arch, and is controlled by the deep peroneal nerve.

What are the upper leg muscles called? Like the forearm, the upper leg, or thigh, has a dense arrangement of many muscles. On the anterior side, the most prominent of the muscles are the sartorius muscle and the four muscles that make up quadriceps muscle group (the . Jan 20,  · Other muscles of the anterior (front) thigh include the pectineus, sartorius, and the iliopsoas, which is made up of the psoas major and iliacus. . The three layers of gluteal muscles, gluteus maximus, gluteus medius, gluteus minimus. Like the forearm, the upper leg, or thigh, has a dense arrangement of many muscles. On the anterior side, the most prominent of the muscles are the sartorius muscle and the four muscles that make up quadriceps muscle group (the “quads”.).

There are three layers of gluteal muscles on the posterior hips, just like there are three layers of muscles in the abdominal trunk. The largest of them is the most superficial muscle, the gluteus maximus. Its origin is on the ilium of the coxal bone, and it inserts part-way down the shaft of the femur. It helps maintain erect posture, abducts the thigh, and rotates the thigh outward. Below the gluteus maximus is the smaller gluteus medius. The gluteus medius muscle helps abducts the thigh along with the gluteus maximus, but can rotate the thigh inward where the gluteus maximus rotates the thigh outward.

The below the gluteus medius are several muscles, one of which is the gluteus minimus , the smallest of the gluteal muscles. It is a synergist for the gluteus medius. Figure The three layers of gluteal muscles, gluteus maximus, gluteus medius, gluteus minimus.

Like the forearm, the upper leg, or thigh, has a dense arrangement of many muscles. The quadriceps sounds like it should be just one muscle, akin to the triceps brachii, but it is a group of four muscles, three visible on the surface, and the fourth obscured.

The three surface muscles of the quadriceps are the rectus femoris in the center, the vastus medialis on the medial side, and the vastus lateralis on the lateral side.

These three muscles are visible in Figure Below the rectus femoris and largely hidden by it is the vastus intermedius. The four muscle of the quadriceps all extend the lower leg, and the rectus femoris additionally can flex the thigh at the hip.

The quadriceps group of four muscles. The view on the left has the rectus femoris cut away to show the vastus intermedius which is below it. The sartorius muscle is a distinctively long and thin muscle that crosses the thigh diagonally. It is visible in Figure In the posterior thigh the bulk of the musculature is made up of three long muscles that are collectively called the hamstrings.

Move from the medial edge to the lateral edge of the posterior thigh, the hamstring muscles are the semimembranous muscle, the semitendinosus muscle, and the biceps femoris muscle. This is why you have to indicate which biceps you are taking about when discussing one or other of these muscles. On the medial edge of the posterior thigh is the gracilis muscle. It is also visible on the medial edge of the thigh from the anterior.
