Flashcards in Muscular system. Deck (36):
1

adductors

a muscle whose contraction moves a limb or other part of the body toward the midline of the body or toward another part.

2

biceps brachii

A muscle whose long head has origin from the supraglenoidal tuberosity of the scapula and whose short head has origin from the coracoid process, with insertion into the tuberosity of the radius, with nerve supply from the musculocutaneous nerve, and whose action flexes and supinates the forearm

3

biceps femoris

A muscle whose long head has origin from the tuberosity of the ischium and whose short head has origin from the lower half of the lateral lip of the linea aspera, with insertion into the head of the fibula, with nerve supply from the tibial nerve for the long head and from the peroneal nerve for the short head, and whose action flexes the knee and rotates the leg laterally.

4

buccinators

a flat, thin muscle in the wall of the cheek.

5

deltoid

each of the three parts of a deltoid muscle, attached at the front, side, and rear of the shoulder.

6

extensors

a muscle whose contraction extends or straightens a limb or other part of the body.

7

external intercostals

Any of the muscles with their origin from the lower border of a rib, with insertion into the upper border of the rib below, with nerve supply from the intercostal nerve

8

external oblique

the largest and the most superficial (outermost) of the three flat muscles of the lateral anterior abdomen.

9

fibularis longus

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

10

flexors

a muscle whose contraction bends a limb or other part of the body.

11

frontalis

is muscle which covers parts of the skull.

12

gastrocnemius

the chief muscle of the calf of the leg, which flexes the knee and foot. It runs to the Achilles tendon from two heads attached to the femur.

13

gluteus maximus

any of three muscles in each buttock that move the thigh, the largest of which is the gluteus maximus.

14

gluteus medius

The middle of the three muscles in each buttock that arises from the outer surface of the ilium, that is inserted into the greater trochanter of the femur, and that acts to abduct and medially rotate the thigh.

15

internal oblique

muscle is a muscle in the abdominal wall that lies below the external oblique and just above the transverse abdominal muscles.

16

atissimus dorsi

a broad, flat muscle on each side of the midback, the action of which draws the arm backward and downward and rotates the front of the arm toward the body.

17

masseter

a muscle that runs through the rear part of the cheek from the temporal bone to the lower jaw on each side and closes the jaw in chewing.

18

orbicularis oculi

is a muscle in the face that closes the eyelids

19

orbicularis oris

is not a simple sphincter muscle like the orbicularis oculi; it consists of numerous strata of muscular fibers surrounding the orifice of the mouth, but having different direction.

20

pectoralis major

is a thick, fan-shaped muscle, situated at the chest

21

rectus abdominus

A large muscle in the front of the abdomen that assists in regular breathing movements,

22

rectus femoris

.is one of the four quadriceps muscles of the human body. The others are the vastus medialis, the vastus intermedius (deep to the rectus femoris), and the vastus lateralis.

23

sartorius

a long, narrow muscle running obliquely across the front of each thigh from the hipbone to the inside of the leg below the knee.

24

semimembranosus

is a muscle in the back of the thigh. It is the most medial of the three hamstring muscles.

25

semitendinosus

. is a long superficial muscle in the back of the thigh; it is one of the hamstrings.

26

soleus

a broad muscle in the lower calf, below the gastrocnemius, that flexes the foot to point the toes downward.

27

sternocleidomastoid

each of a pair of long muscles that connect the sternum, clavicle, and mastoid process of the temporal bone and serve to turn and nod the head.

28

temporalis

a fan-shaped muscle that runs from the side of the skull to the back of the lower jaw and is involved in closing the mouth and chewing.

29

tibialis anterior

is a muscle that originates in the upper two-thirds of the lateral (outside) surface of the tibia

30


trapezius

either of a pair of large triangular muscles extending over the back of the neck and shoulders and moving the head and shoulder blade.

31

triceps brachii

a large muscle that extends the entire length of the posterior surface of the humerus

32

vastus lateralis

is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh.

33

vastus medialis

extensor muscle located medially in the thigh that extends the knee. The vastus medialis is part of the quadriceps muscle group.

34

zygomaticus

slender band of muscle on each side of the face that arises from the zygomatic bone,

35

quadriceps

the large muscle at the front of the thigh, which is divided into four distinct portions and acts to extend the leg.

36

hamstring

any of five tendons at the back of a person's knee.
