Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Question

When motor units are recruited to participate in tension development in a muscle, the order of recruitment is typically:

Question 13 options:

	from slow twitch to fast twitch
	from fast twitch to slow twitch
	it depends on the type of contraction
	related to the size and shape of the muscle

Arrange the following in statements in the order that they occur during muscle contraction: 1-10 ACh leaves the synaptic knob and enters the synaptic cleft The action potential is carried deep into the muscle cell by T tubules The muscle cell relaxes and lengthens Myosin binds to and pulls on actin, resulting in muscle shortening Calcium attaches to troponin As calcium re-enters the sarcoplasmic reticulum, its concentration at the myofilaments decreases Calcium is released from the sarcoplasmic reticulum Tropomyosin rolls out of the way, exposing actin ACh diffuses across the synaptic cleft and attaches to protein receptors on the sarcolemma, resulting in muscle "excitation" Na+ enters the muscle cell and K+ exits, resulting in an action potential
Skeletal muscle is described as striated. What are the lighter, thinner stripes noted under the microscope? Group of answer choices troponin actin myosin dystrophin Rather than innervating individual muscle fibers, motor neurons often innervate two or more muscle fibers. The motor neuron and the muscle fibers it innervates are together called a: Group of answer choices motor unit myofibril muscle fascicle motor fascia Fast glycolytic muscle fibers allow for relatively quick ATP energy production by splitting glucose (but eventually leads to fatigue), a process described as: Group of answer choices fermentation aerobic pathway anaerobic pathway ATP reserve use
