Chapter 11 Flashcards
support and position axial skeleton
axial muscle
support move, brace limbs
appendicular muscle
fixed attachment
origin
attachment that moves towards the origin
insertion
fascicles run parallel to the long axis of the muscle, high endurance
parallel muscle
what is an example of parallel muscle
biceps brachii
fascicles extend over broad area and converge to a common attachment
convergent muscle
what is an example of a convergent muscle?
pectoralis major
fascicles from a common angle to their tendon, feather appearance
pennate muscle
what is an example of a pennate muscle?
extensor digitorum, biceps femoris, deltoid
fascicles are arranged in a circle around an opening or recess
sphincter muscle
what is an example of sphincter muscles?
orbicularis oris/oculi
prime movement, produces desired movement
agonist
oppose the agonist, must stretch in order to allow for the desired action to occur
antagonist
helper muscle, aids the agonist as its contraction allows the agonist to work more efficiently
