muscle names

gastrocnemius

is a muscle located on the back portion of the lower leg, being one of the two major muscles that make up the calf. The other major calf muscle, the soleus muscle, is a flat muscle that lies underneath the gastrocnemius.

vastus lateralis

it is located on the side of the thigh. This muscle is the largest of the quadriceps group (often called quads) which also includes the rectus femoris, the vastus intermedius, and the vastus medialis.

gracilis

it is one of the muscles found in the groin. It starts at the external point of the ischiopubic ramus (on the pubic bone) and extends down to the upper medial (middle) shaft of the tibia, or shinbone.

sartorius

it is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment. Its upper portion forms the lateral border of the femoral triangle.

transversus abdominus

it s a muscle layer of the anterior and lateral (front and side) abdominal wall which is deep to (layered below) the internal oblique muscle.

latissimus dorsi

s one of the largest muscles in the back. There muscle is divided into two segments, which are configured symmetrically along the backbone. The muscle is located in the middle of the back, and it is partially covered by the trapezius.

sternocleidomastoid

the manubrium of the sternum (sterno-) and the clavicle (cleido-), and has an insertion at the mastoid process of the temporal bone of the skull.

soleus

It is located on the back of the lower leg and originates at the posterior (rear) aspect of the fibular head and the medial border of the tibial shaft.

frontalis

It is located on the front of the head. The muscle has no bony attachments

deltoid

The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder. It is named after the Greek letter delta, which is shaped like an equilateral triangle.

external oblique

The external obliques on either side not only help rotate the trunk, but they perform a few other vital functions. These muscles help pull the chest, as a whole, downwards, which compresses the abdominal cavity.

external oblique

The external obliques on either side not only help rotate the trunk, but they perform a few other vital functions. These muscles help pull the chest, as a whole, downwards, which compresses the abdominal cavity. Although relatively minor in scope, the external oblique muscle also supports the rotation of the spine

biceps femoris

The long head is a part of the hamstring muscle group that occupies the posterior section of the thigh. The hamstring muscles may be considered extensors of the thigh.

zygomaticus

is a muscle that controls facial expression, drawing the mouth's angle upward and outward. The zygomaticus major muscle starts at the cheekbone and extends to the corner of the mouth.

deltoid

is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder. It is named after the Greek letter delta, which is shaped like an equilateral triangle.

adductor muscle

is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle

fibularis longus

is a superficial muscle in the lateral compartment of the leg, and acts to evert and plantar flex the ankle.

gluteus maximus

is located in the buttocks and 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.

semitendinosus

is one of three hamstring muscles that are located at the back of the thigh. The other two are the semimembranosus muscle and the biceps femoris. The semitendinosus muscle lies between the other two. These three muscles work collectively to flex the knee and extend the hip.

trapezius

is one of two large superficial muscles that extend longitudinally from the occipital bone to the lower thoracic vertebrae and laterally to the spine of the scapula

triceps brachii

is the large muscle on the back of the upper limb of many vertebrates. It is the muscle principally responsible for extension of the elbow joint (straightening of the arm)

temporalis

it is a large, thin fan-shaped muscle located in the side of the skull above and in front of the ear.

vactus medialis

it is a part of the quadriceps muscle group, located on the front of the thigh. It is the most medial, or inner, of the quadriceps muscles.

tibialis anterior

merges from the upper lateral (outer) surface of the tibia, or shinbone, and from the interosseous membrane. The muscle inserts into the base of the first metatarsal bone in the foot, located just behind the big toe.

adductor goup

Adductor brevis. Adductor longus. Adductor magnus. Adductor minimus This is often considered to be a part of adductor magnus. pectineus. gracilis. Obturator externus and are also part of the medial compartment of thigh.

gluteus medius

During gait, these two muscles function principally in supporting the body on one leg, in conjunction with the tensor fasciae latae, to prevent the pelvis from dropping to the opposite side

orbicularis oris

Located in the face, the orbicularis oris muscle controls movements of the mouth and lips. Specifically, it encircles the mouth, originating in the maxilla (upper jaw and palate) and mandible (lower jaw) bones.

orbicularis oculi

The orbicularis oculi muscle lies directly underneath the surface the skin, around the eyes. Its function is to close the eyelid, and to help in the passing and draining of tears through the punctum, canaliculi, and lacrimal sac, all parts of the tear drainage system.

pectoralis major

The pectoralis major muscle is a large muscle in the upper chest, fanning across the chest from the shoulder to the breastbone.

biceps brachii

it is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. Both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm

masseter

it is assisted by three other muscles: the temporalis, medial pterygoid, and lateral pterygoid. The four muscles work together to pull the jaw down and back up again. The masseter is the key muscle that pulls the mandible upward.

rectus femoris

it is attached to the hip and helps to extend or raise the knee. This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip.

rectus abdominis

it is located in the front of the body, beginning at the pubic bone and ending at the sternum. It is located inside the abdominal region. The muscle is activated while doing crunches because it pulls the ribs and the pelvis in and curves the back.
