short fascicles in relation to total muscle length; tendon extends nearly entire length of muscle
pennate
Fascicles nearly to longitudinal axis of muscle; terminate in flat tendons; muscle tapers toward tendon, where diameter is less than at belly. Ex: digastric muscle
fusiform
fascicles arranged on only one side of tendon
ex:extensor digitorum longus muscle
Unipennate
Fascicles arranged on both sides of centrally positioned tendons ex: rectus femurs muscle
Bipennate
Fascicles attach obliquely from many directions to several tendons ex: deltoid muscle
mulipennate
3 origin muscle

What prime mover muscles are called
agonist
A muscle that has an action opposite that of prime mover (agonist) and yields to the movement of the prime mover
Antagonist
the muscle responsible for producing a desired motion (also called prime mover)
Agonist
A muscle that stabilizes the origin of the prime mover so that the prime mover can act more differently
