Muscular System (Ventral)

Question 1

Adductor Longus

Answer 1

Skeletal muscle in the thigh, one of the adductor muscles of the hip, main function to adduct the thigh.

Question 2

Adductor Magnus

Answer 2

Largest and strongest muscle of the medial compartment of the thigh, consists of the adductor longus, adductor brevis, pectineus, and gracilis muscles.

Question 3

Deltoid

Answer 3

A large muscle for lifting the arm and giving the shoulder its range of motion. Located in the uppermost part of the arm at the shoulder. Tendons attach the deltoid to the collarbone, shoulder blade, and upper arm.

Question 4

Extensor Cruris

Answer 4

Originates by a slender tendon from the ventral surface of the medial condyle of the femur and passes over the knee to insert as a fleshy belly on the ventro-lateral surface of the tibiofibula.

Question 5

External Oblique

Answer 5

The lateral abdominal wall muscle that is the most superficial, immediately superficial to the internal oblique.

Question 6

Flexor Tarsi Anterior

Answer 6

A long narrow muscle adhering closely behind the tibio-fibula, a very small muscle found between two distal ends of the tibialis anticus.

Question 7

Geniohyoid

Answer 7

A narrow muscle situated superior to the medial border of the mylohyoid muscle. It is named for its passage from the chin to the hyoid bone. Geniohyoid muscle. Anterior view. Geniohyoid muscle labeled at upper center left

Question 8

Gracilis Major

Answer 8

The most superficial muscle of the inside of the thigh that arises from the lower part of the pubic symphysis and the anterior half of the pubic arch and that has its tendon inserted into the inner surface of the shaft of the tibia below the tuberosity, and that acts to adduct the thigh and to flex the leg at the knee and to assist in rotating it medially, the major is the upper muscle and minor is the lower.

Question 9

Gracilis Minor

Answer 9

The most superficial muscle of the inside of the thigh that arises from the lower part of the pubic symphysis and the anterior half of the pubic arch and that has its tendon inserted into the inner surface of the shaft of the tibia below the tuberosity, and that acts to adduct the thigh and to flex the leg at the knee and to assist in rotating it medially, the major is the upper muscle and minor is the lower.

Question 10

Linea Alba

Answer 10

Is a single midline fibrous line in the anterior abdominal wall formed by the median fusion of the layers of the rectus sheath medial to the bilateral rectus abdominis muscles. It attaches to the xiphoid process of the sternum and the pubic symphysis.

Question 11

Mylohyoid

Answer 11

Is a paired muscle running from the mandible to the hyoid bone, forming the floor of the oral cavity of the mouth.

Question 12

Pectoralis Epicoracoidea

Answer 12

Medial end of the coracoid, which is synchondrotically fused to the epicoracoid cartilage.

Question 13

Pectoralis Sternalis

Answer 13

Medial end of the clavicle, which usually lies on the ventral side of the epicoracoid cartilage, just posterior to the epicoracoid bridge.

Question 14

Rectus Abdominis

Answer 14

(Abdominal muscle) Is a paired muscle running vertically on each side of the anterior wall of the human abdomen, as well as that of some other mammals. There are two parallel muscles, separated by a midline band of connective tissue called the linea alba.

Question 15

Sartorius

Answer 15

A thin flat muscle which traverse the thigh obliquely.

Question 16

Semimembranosus

Answer 16

Is a relatively large muscle that originates from a small facet on the rough superolateral surface of the ischial tuberosity. The tendon of semimembranosus appears at the level of the mid-thigh and continues caudally toward the point of insertion at the medial condyle of the tibia.

Question 17

Semitendinosus

Answer 17

Is a fusiform muscle of the posterior compartment of thigh. Along with semimembranosus and long head of biceps femoris it comprises a group called the hamstring muscles with which it shares these three common features; They all attach between the ischial tuberosity of pelvis and bones of the leg.

Question 18

Sterno-radialis

Answer 18

Next to the preceding and arises in the midventral line passing outwards, piercing the distal portion of the deltoid.

Question 19

Submentalis

Answer 19

Is a branch of the facial artery that runs on the underside of the chin.

Question 20

Tendon of Achilles

Answer 20

Is a tough band of fibrous tissue that connects the calf muscles to the heel bone (calcaneus). The Achilles tendon is also called the calcaneal tendon. The gastrocnemius and soleus muscles (calf muscles) unite into one band of tissue, which becomes the Achilles tendon at the low end of the calf.

Question 21

Tibialis Posticus

Answer 21

– (Tibialis posterior) Is the most central and deepest muscle located in the posterior aspect of the leg. These muscles are located posterior to the tibia, fibula and interosseous membrane. Tibialis posterior is hidden from view by the large, superficial muscles of the leg; gastrocnemius and soleus.

Question 22

Triceps Femoris

Answer 22

Large muscle covering the entire thigh from anterior part to the posterior margin. The proximal end is divided into three heads.
