After death, calcium pumps no longer function and the calcium ion concentration of muscle fiber cytoplasm increases. The result is rigor mortis a state or postmortem muscle contraction. Explain why this contraction occurs and why it ends only when myosin heads begin to break down.
Which arrangement best describes a bipennate muscle? The muscle fibers feed in on an angle to a long tendon from both sides. The muscle fibers feed in on an angle to a long tendon horn all directions. The muscle fibers feed in on an angle to a long tendon horn one side. The muscle fibers on one side of a tendon feed into it at a certain angle and muscle fibers on the other side of the tendon feed into it at the opposite angle.
A muscle that has a pattern of fascicles running along the long axis of the muscle has which of the following fascicle arrangements? circular pennate parallel rectus
The correct order for the smallest to the largest unit of organization in muscle tissue is ________. fascicle, filament, muscle fiber, myofibril filament, myofibril, muscle fiber, fascicle muscle fiber, fascicle, filament, myofibril myofibril, muscle fiber, filament, fascicle
The muscles of a professional sprinter are most likely to have ________. 80 percent fast-twitch muscle fibers and 20 percent slow-twitch muscle fibers 20 percent fast-twitch muscle fibers and 80 percent slow-twitch muscle fibers 50 percent fast-twitch muscle fibers and 50 percent slow-twitch muscle fibers 40 percent fast-twitch muscle fibers and 60 percent slow-twitch muscle fibers
The cell membrane of a muscle fiber is called ________. myofibril sarcolemma sarcoplasm myofilament
After death, a person no longer makes ATP, so calcium stored in the sarcoplasmic reticulum diffuses down its concentration gradient into the muscle cytoplasm. This result is rigor mortis----an unbreakable state of muscle contraction that stiffens the body for a few days until muscles begin to decay. Explain why this contraction occurs.
Every skeletal muscle fiber is supplied by a motor neuron at the NMJ. Watch this video (http://openstaxcollege.org/l/skelmuscfiber) to learn more about what happens at the neuromuscular junction. (a) What is the definition of a motor unit? (b) What is the structural and functional difference between a large motor unit and a small motor unit? Can you give an example of each? (c) Why is the neurotransmitter acetylcholine degraded after binding to its receptor?
