Muscles fasicles arragnement Flashcards
circular
arranged in a circle around an opening at that acts as a sphincter
examples of circular
obicular orbis
obicular oculi
convergent
broadly distributed fasicles converge on a single tendon
convergent examples
pectoralis major and minor
convergent characteristics
if long have wide range of motion
fibers side by side can result in muscles that have less strength
pennate
originates from a tendon that runs the length of the entire muscle
unipennate
fasicles on only one side of the tendon
ex of unipennate
palmar interosseous
semimembraneous
bipennante
fasicles are on both side of tendons
bipennate ex
rectus femoris
multipennate
fasicles arranged at many places around tendon
spread out at angles to smaller tedones
ex multipennate
deltoid and knee muscles
fusiform
lie parrallel to long axis of muscle and belly larger in diameter than the ends
fusiform example
biceps brachii and triceps brachii
parrallel
lie parrallel to one another and long axis of muscle
terminate on flat tendon that spans the entire muscle
