Chapter 3, Problem 1WS

Watch this animation (http://openstaxcollege.org/l/hipreplace) to observe hip replacement surgery (total hip arthroplasty), which can be used to alleviate the pain and loss of joint mobility associated with osteoarthritis of the hip joint. What is the most common cause of hip disability?

The ________ opposes or resist, the action  caused by the prime mover Antagonist  Prime mover Agonist synergist   Th ________of as muscle is the tendinous attachment on the bone that moves the least during contraction of the muscle  Belly Insertion Origin architecture   The _________of a muscle is the tendinous attachment on the bone that moves the most during contraction of the muscle Architecture Insertion Origin  belly

Arrange the steps of muscle innervation and contraction in response to touching a hot plate. appendage is removed from stimulus v movement is produced muslce fibers work together to produce action muscle contraction occurs and the sarcomere shortens Myosin heads bind thin filament Calcium binds troponin Calcium is released T tubules carry the action potential to the sarcoplasmic reticulum Action potential is generated in the sarcolemma as a result of opened sodium channels The presynaptic cell releases acetylcholine Signal arrives at the neuromuscular junction Sensory receptors detect uncomfortable heat Afferent neurons carry impulse to the central nervous system Signal reaches the reflex arc in the central nervous system and is directed out through the anterior horn Signal travels through the motor units > |> > > |> > > > > > > > >

Contraction of muscle fibers in skeletal muscle is initiated by the uptake of calcium by the transverse (T) tubules. O the release of calcium from the transverse (T) tubules. O the release of calcium from the mitochondria. the uptake of calcium by the sarcoplasmic reticulum. the release of calcium from the sarcoplasmic reticulum.
