Exam 3: chapter 11

__ __ can move a load over a great DISTANCE. they can change length and fascicles run parallel to the length of muscle

parallel muscles

__ __ have fascicles that spread out like fan on one end and
converge to a single point on other.produces less tension and distance than parallel muscle but provide VERSATILITY

convergent muscles

__ __ are feather like and have fascicles that are arranged at an angle from the tendon . they produce more tension than parallel muscles but can’t move as far

pennate muscles

__ muscles have fascicles angled on one
side of tendon

unipennate

__ muscles have tendons in the middle with angled fascicles on
either side

bipennate

__ muscles have a branched tendon with fascicles organized
around each branch

multipennate

__ __ have a concentric arrangement of fascicles and function to decrease the diameter of openings, and guard entrances and exits

circular muscles

the __ is where the fixed end of the muscle
attaches to bone, cartilage, or CT

origin

the __ is where the moveable end attaches

insertion

the __ is the specific movement produced by
the muscle during contraction

action

an __ is the prime mover and is the muscle most
responsible for the specific action

agonist

a __ is a muscle with the same action as the agonist, and assists agonist at the beginning of contraction when fiber length is not optimal for agonist

synergist

an ___ is a muscle whose action opposes the agonist (produces the opposite action) to fine tune movement by the agonist

antagonist

the ___ is named for part of body where its located e.g. Brachii, Abdominis

location

the ___ __ is named for how the fascicles are organized with respect to the body e.g. Rectus = straight, Oblique = angle

fascicle organization

the __ __ is named for its depth when layered
e.g. Externus/ Superficialis =top, surface, Internus/ Profundus =deep

relative position

the __ is named for the number of tendons
e.g. triceps, biceps

structure

the __  is named for the shape of muscle
e.g. trapezius = trapezoid, deltoid = triangle, soleus = fish

shape

__ means bigger

major

__ means biggest

maximus

__ means long

longus

__ means great

vastus

name for regions of attachment, __ first, __ second
e.g. Sternocleidomastoid
O = manubrium of sternum and medial clavicle
I = mastoid process

origin, insertion

the __ is named for the action performed and region acted upon
e.g. Extensor digitorum

action
