muscloskeletal system Flashcards
3 types of muscle tissue?
smooth, cardiac and skeletal muscle
which 2 of 3 are involuntary?
cardiac and smooth muscle
what is a smooth muscle?
surrounds the body’s internal organs, like blood vessels, hair follicles, & the urinary, genital and digestive tracts
what is a cardiac muscle?
found only in 1 place the heart, creates the action that pumps blood from the heart to the rest of the body
what is the skeletal muscle
muscles that are attached to bones by tendons and other tissues (makes up 30-40% of body weight)
the 4 components are?
connective tissue, tendons, ligaments and cartilage tissue
connective tissue..?
binds bones and muscles together
tendons ..?
muscle fibre that connects bones
directly through tissue
ligaments..?
bones bound together tightly
with other bones
cartilage tissue
at end of bone and prevents
bones from grinding against each other
agonist is?
muscle primarily responsible for movement of a body part
antagonist is?
the muscle that counteracts the agonist, lengthening when agonist muscle contracts
origin is?
the point where the muscle attaches to the more stationary of the bones
insertion is?
other end of orgin, point where the muscle attaches to the bone that is moved the most
naming (action of the muscle)
ex; flexion/extension, flexor capri ulnaris, extensor carpi ulnaris
