Muscular System Flashcards
is an organ system, involved majorly in
the movement of the body.
Muscular System
There are nearly ___ muscles that are
connected to the bones of the skeletal
system, which roughly half make up the
human’s body weight.
700
ability of the muscle to
respond to stimuli
Excitability
ability of muscle to contract
contract or shorten its size
Contractibility
ability of muscle to stretch
Extensibility
ability of muscle to return to original length after stretching
Elasticity
Covers the walls of the heart. Moves Involuntary and are striated, as well as uninucleated
Cardiac Muscle
Covers the walls of the internal organs. Are also involuntary, non-striated and
uninucleated
Visceral Muscle
Attached to bones, is responsible for skeletal
movements. Voluntary, striated and multi-
nucleated.
Skeletal Muscle
Muscles that produces any particular movement
in the body
Agonist/Prime Movers
muscles that produces the opposite effect of
the agonist
Antagonist
muscles that help to stabilize a movement and
reduce extraneous movements
Synergist
muscles that assist in movement by holding the
origin stable
Fixator
Types of muscle fibers?
Slow twitch & fast twitch
This forms the central axis of the human body.
This provides support and protection and a surface for the attachment of the muscles that move the head, neck and trunk.
This also stabilizes parts of the appendicular skeleton
