Arrangements of fascicles in skeletal muscle provide examples. Flashcards
arranged in different patterns
Fascicles
Origin of the muscle is broad, Fascicles converge toward the tendon of insertion
Convergent
Example of convergent is _________
Pectoralis major
fascicles run parallel to the long axis of the muscle
Parallel
Example of parallel are _____________
fusiform and sartorius
Fascicles are arranged in concentric rings, Surround external body openings
Circular
Examples of circular is what
orbicularis oculi
A ________________ is a muscle with fascicles that attach
obliquely to its tendon. These types of muscles generally
allow better stabilization and force production but less
flexibility
Pennate
fascicles insert into one side of the tendon
Unipennate
fascicles insert into the tendon from both sides
Bipennate
fascicles insert into one large tendon from all
sides
Multipennate
Example of multipennate
Deltoid muscle
Example of bipinnate
Rectus femoris muscle
Example of Unipennate
Extensor digitorum longus muscle
