3 types of muscle tissue
skeletal, smooth and cardiac muscle
skeletal muscle
comprised of long, cylindrical, unbranched cells with striations and multiple peripheral nuclei, and it is under voluntary control

functions include: movement, facial expression, posture, breathing, speech, swallowing and excretion

cardiac muscle
short branched cells with striations and intercalated discs, it is under involuntary control.

found in: the heart
short branched cells with striations and intercalated discs, it is under involuntary control.

found in: the heart
smooth muscle
short fusiform cells; nonstriated with only one central nucleus, and similar to cardiac muscle it is under involuntary control

found in: sheets of muscle in the viscera, iris, hair follicles, sphincters, aids in swallowing, GI tract functions, ...
short fusiform cells; nonstriated with only one central nucleus, and similar to cardiac muscle it is under involuntary control

found in: sheets of muscle in the viscera, iris, hair follicles, sphincters, aids in swallowing, GI tract functions, labor contractions, control of airflow, erection of hairs and control of pupil
agonists
type of muscles that directly cause the movement to occur.

AKA: Prime Movers
antagonists
type of muscles that act in opposition to the movement generated by the agonists and
are responsible for returning a limb to its initial position
synergists
type of muscles that assist in performing the movement with the agonists

AKA: Neutralizers
fixators
type of muscles that immobilize the origin of prime movers so that all tension is exerted at
the insertion.

AKA: Stabilizers
