Rabbit Muscles Flashcards
what are the two groups of muscles
voluntary and involuntary
what are the voluntary muscles responsible for
all coordinated movement
what are the voluntary muscles innervated by
cerebrospinal nerves
what are the involuntary muscles
contractile tissues
where are the involuntary muscles found
in the walls of the alimentary tract, blood vessels, urinary system, reproductive ducts, respirratory passageways, and other viscera
what is the musculature of the heart
a specialized type of involuntary muscle
what is the involuntary muscle innervated by
branches of the autonomic nervous system
what is the voluntary muscle typically connected to
bone
what is the origin of voluntary muscle
the site of attachment on a fixed bone
what is the insertion of a voluntary muscle
the site on a bone that moves
what is the most common attachment of a muscle
tendon
how is a tendon described
glistening white cord of fibrous connective tissue
what does it mean for a tendon to be aponeurosis
the tendon is broad and flat
what is a raphe
same muscle from both sides of the body joins in mid dorsal line of body and the line of fusion forms a ridge called the raphe
what is the function of muscles
to move skeletal elements together to act as a system of levers
why are muscles able to move skeletal elements
because theyre suspended over joints and are capable of contraction or shortening
what is a flexor
muscle that by its contraction bends a limb or any portion of it
what is an extensor
straightens out the limb or binds the bone into line
what is an abductor
muscle that draws laterally from axis of limb (moves outward)
what is an adductor
muscle that draws laterally towards the axis of the limb (moves inward)
what are fascia
muscles are bound together by sheets of connective tissue known as fascia
what are the two kinds of fascia
superficial and deep
what muscles are preserved in metamerism in mammals
intercostal, intervertebral, rectus abdominus
