Exercise 13: Review Sheet: Gross Anatomy of the Muscular System

A prime mover, or _______, produces a particular type of movement.
agonist

Skeletal muscles are named on the basis of many criteria. Name one
direction of fibers, size, location, shape, or action.

True or false. Muscles of facial expression differ from most skeletal muscles because they usually do not insert into a bone.
true

The _______ musculature includes muscles that move the vertebral column, the ribs, and the abdominal wall.
trunk

Muscles that act on the _______ cause movement at the hip, knee, and foot joints.
lower limb

This two-headed muscle bulges when the forearm is flexed. It is the most familiar muscle of the anterior humerus. It is the:
biceps brachii

These abdominal muscles are responsible for giving me my “six-pack.” They also stabilize my pelvis when walking. They are the _______ muscles.
rectus abdominis

This lower limb muscle, which attaches to the calcaneus via the calcaneal tendon and plantar flexes the foot when the leg is extended, is he tibialis anterior/gastrocnemius
gastrocnemius

The _______ is the largest and most superficial of the gluteal muscles
gluteus maximus

True or false: the biceps femoris is located in the anterior compartment of the thigh.
false

gluteus maximus
location of the muscle relative to a bone or body region; relative size of the muscle

adductor magnus
action of the muscle; relative size of the muscle

biceps femoris
number of origins; location of the muscle relative to a bone or body region

transverse abdominis
location of the muscle relative to a bone or body region; direction in which the muscle fibers run relative to some imaginary line

extensor carpi ulnaris
action of the muscle; location of the origin and/or insertion of the muscle; location of the muscle relative to a bone or body region

trapezius
shape of the muscle

rectus femoris
location of the muscle relative to a bone or body region; direction in which the muscle fibers run relative to some imaginary line

external oblique
location of the muscle relative to a bone or body region; direction in which the muscle fibers run relative to some imaginary line

Prime mover (agonist)
term for the biceps brachii during forearm flexion; term for the gluteus maximus during thigh extension when walking up stairs.

synergist
term that describes the relation of brachioradialis to biceps brachii during forearm flexion

antagonist
term for the triceps brachii during forearm flexion; term for the iliopsoas during thigh extension

Fixator
term for the rotator cuff muscles and deltoid when the forearm is flexed and the hand grabs a tabletop to lift the table

used in smiling
zygomaticus major and minor

used to suck in your cheeks
buccinator

used in blinking and squinting
orbivularis oculi

used to pout (pulls the corners of the mouth downward)
depressor anguli oris; mentalis

raises your eyebrows for a questioning expression
epicranius (frontal belly)

used to form the vertical frown crease on the forehead
corrugator supercilii

your kissing muscle
orbicularis oculi

prime mover of jaw closure
masseter

tenses skin of the neck during shaving
platysma

a major flexor of the vertebral column
rectus abdominis

prime mover for arm extension
latissimus dorsi

prime mover for arm flexion
pectoralis minor

assume major responsibility for forming the abdominal girdle (three pairs of muscles)
external oblique, internal oblique, transversus abdominis, and rectus abdominis

prime mover of arm abduction
deltoid (cut)

important in arm adduction; antagonist of the arm abductor (two muscles)
latissimus dorsi and pectoralis minor

moves the scapula forward and rotates scapula upward
serratus anterior

small, inspiratory muscles between the ribs; elevate the rib cage
external intercostals

extends the head
trapezius

pull the scapulae medially
rhomboids.
