muscular system Flashcards
part 1
types of muscle tissue
skeletal muscle, cardiac, smooth
skeletal muscle
attached to the bones and responsible for movents of our body
musles that are striated and very strong
skeletal
what makes skeletal muscles unique
the only voluntary tissue in the body
cardiac
found in our heart helps pumps blood through out the body
striated can not be moved valuntary
cardiac
smooth
found in the internal organs like stomach, intestine, as well as blood vessels
not striated only musle that is not striated and also involuntary
smooth muscle
smooth muscle
is the weakest of the three types
function of muscle
resposible for the movement of the body
how do muscle generate force
by contracting and producing movement by moving the bones to which where they are attached to
how many named muscles are there in the body
over 700
how much does muscle weigh
it makes up half of our body weight
how do nerves work with muscle
nerves control muscles by sending or eletrical impulses to the muscles
the effect neves have on muscle
eletrical impulses causes the muscle to contract and generate force
where does the nerve impulse orginate
the brain to spinal cord send down to the axon to muscle nerce to muscle fiber
