Muscles of the Body

Hamstring Group

A hamstring is one of the three posterior thigh muscles in between the hip and the knee. Help with the support and flexion of the knee

Gastrocnemius

Along with the soleus muscle, the gastrocnemius forms half of the calf muscle. Its function is plantar flexing the foot at the ankle joint and flexing the leg at the knee joint.

IIiopsoas

Iliopsoas muscle: A blending of two muscles (the iliacus and psoas major) that run from the lumbar portion of the vertebral column to the femur. The main action of the iliopsoas is to flex the thigh at the hip joint.

Peroneus Longus

In human anatomy, the peroneus longus is a superficial muscle in the lateral compartment of the leg, and acts to evert and plantarflex the ankle.

Adductor Longus

It also has limited actions in both flexion and rotation of the vertebral column. One side of the obliques contracting can create lateral flexion.

Rectus femoris

Located at the front of the thigh and helps with the extension and movement of the knee

Quadriceps

Quadriceps femoris muscle, large fleshy muscle group covering the front and sides of the thigh. It has four parts: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.

Rectus Abdominal Oblique

The abdominal muscles form the anterior and lateral abdominal wall and consist of the external abdominal obliques, the internal abdominal obliques, the rectus abdominis and the transversus abdominis . Acting together these muscles form a firm wall that protects the viscera and they help to maintain erect posture.

Adductor Magnus

The adductor magnus is a large triangular muscle, situated on the medial side of the thigh.As an adductor, it contracts and pulls the hip towards the body's midline.

Brachialis

The brachialis is a muscle in the upper arm that flexes the elbow joint. It lies deeper than the biceps brachii, and makes up part of the floor of the region known as the cubital fossa. The brachialis is the prime mover of elbow flexion.

Deltoid

The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder which is responsible for arm and shoulder movement and support.

External Abdominal Oblique

The external oblique functions to pull the chest downwards and compress the abdominal cavity, which increases the intra-abdominal pressure,

Facial Muscles

The facial muscles are a group of striated skeletal muscles innervated by the facial nerve that, among other things, control facial expression.

Gluteus Maximus

The gluteus maximus is the main extensor muscle of the hip. It is the largest and most superficial of the three gluteal muscles and makes up a large portion of the shape and appearance of each side of the hips. The Gluteus Maximus is regarded as one of the strongest muscles in the human body. It is connected to the coccyx, or tailbone, as well as other surrounding bones. The gluteus maximus muscle is responsible for movement of the hip and thigh.

Gluteus Minimum

The gluteus minimus is one of the secondary muscles that can produce hip extension. This muscle is located deep and somewhat anterior to (in front of) the gluteus medius. It is a broad and triangular muscle. they help with the adduction of the hip.

Gracilis Muscle

The gracilis muscle is one of the muscles found in the groin. It starts at the external point of the ischiopubic ramus and extends down to the upper medial shaft of the tibia, or shinbone. The gracilis is responsible for hip adduction and assists knee flexion.

Gracilis

The gracilis muscle is one of the muscles found in the groin. The gracilis is responsible for hip adduction and assists knee flexion.

Latissimus Dorsi

The latissimus dorsi a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction, flexion from an extended position, and medial internal rotation of the shoulder joint.

Pectineus

The pectineus muscle is a flat, quadrangular muscle, situated at the anterior part of the upper and medial aspect of the thigh. The pectineus muscle is the most anterior adductor of the hip. The muscle does adduct and internally rotate the thigh but its primary function is hip flexion.

Pectoriallis Major

The pectoralis major muscle is a large muscle in the upper chest, fanning across the chest from the shoulder to the breastbone. The two pectoralis major muscles, commonly referred to as the "pecs," are the muscles that create the bulk of the chest.

Peroneus Brevis

The peroneus brevis muscle (or fibularis brevis) lies under cover of the peroneus longus, and is the shorter and smaller of the peroneus muscles. It is meant to plantarflex the ankle

Peroneus Maximus

The peroneus longus muscle, whose name means "long muscle of the fibula" is a major muscle of the lower leg that plantar flexes and everts the foot at the ankle. Also known as the fibularis longus, it is the longest muscle that attaches to the fibula and is used specifically when balancing one's weight on one foot.

Sartorius

The sartorius muscle is the longest muscle in the entire human body. The sartorius muscle arises from the anterior superior iliac spine on the lateral edge of the hip bone. From the lateral hip, it descends obliquely across the hip joint and thigh, running medially and inferiorly toward the medial edge of the knee.

Semitendinosis

The semitendinosus muscle is one of three hamstring muscles that are located at the back of the thigh. part of a set of three muscles that work collectively to flex the knee

Soleus

The soleus is a powerful muscle in the back part of the lower leg (the calf). It runs from just below the knee to the heel, and is involved in standing and walking.

Sternocleidomastoid

The sternocleidomastoid is a long muscle in the side of the neck that extends up from the thorax to the base of the skull behind the ear. When the sternocleidomastoid on one side contracts, the face is turned to the opposite side. When both muscles contract, the head is bent toward the chest.

Tibialis Anterior

The tibialis anterior is a muscle in humans that originates in the upper two-thirds of the lateral surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. The tibialis anterior muscle helps with dorsiflexion, which is the action of pulling the foot toward the shin.

Trapezius

The trapezius is one of the major muscles of the back and is responsible for moving, rotating, and stabilizing the shoulder blade and extending the head at the neck.

Triceps Brachii

The triceps brachii muscle is a large muscle on the back of the upper limb of many vertebrates. It is the muscle principally responsible for extension of the elbow joint

Triceps Brachii

The triceps brachii muscle is a large muscle on the back of the upper limb of many vertebrates. It is the muscle principally responsible for extension of the elbow joint.

Vastus Lateralis

The vastus medialis is a muscle present in the anterior compartment of thigh, and is one of the four muscles that make up the quadriceps muscle. The others are the vastus lateralis, vastus intermedius and rectus femoris. It extends and stabilizes knee

Vastus medialis

The vastus medialis is an extensor muscle located medially in the thigh that extends the knee. Helps move the knee when flexing.
