skeletal muscle
striated; voluntary
smooth muscle
non-striated; involuntary; lines internal organs~ peristalsis
cardiac muscle
striated; involuntary
automaticity
the ability to move a muscle to contract without the involvement of a nerve supply . Property of visceral, smooth, and cardiac muscles
contractililty
the ability of a skeleton to contract (shorten) ex) flexing your arm
elasticity
the ability of skeletal muscle fibers to resume their resting length when stretching force is removed. ex) trampoline springs
excitability
also called irritability; ability of skeletal muscles to receive and respond to a nerve supply by contracting. Ex) nerves send messages to the heart
extensibility
ability of the skeletal muscles to be stretched. Ex) extensibility is evident in the hamstring and calf when you bend down to touch your toes.
origin
the attachment site that does not move when muscles contract
insertion
attachment site that moves during muscular contraction
tendon
band of fibrous tissue that connects muscle to bone
ligament
