What special characteristics of the presynaptic neuron (motor neuron) and motor end-plate (postsynaptic membrane in the NMJ) make it possible (and likely) that the threshold for an action potential will be reached in the muscle fiber
Why is the latent period longer during an isotonic twitch of a skeletalmuscle fiber than it is during an isometric twitch?a. Excitation–contraction coupling is slower during an isotonic twitch.b. Action potentials propagate more slowly when the fiber is shortening,so extra time is required to activate the entire fiber.c. In addition to the time for excitation-contraction coupling, it takesextra time for enough cross-bridges to attach to make the tension in themuscle fiber greater than the load.d. Fatigue sets in much more quickly during isotonic contractions, andwhen muscles are fatigued the cross-bridges move much more slowly.e. The latent period is longer because isotonic twitches only occur in slow(type I) muscle fibers.
Why is it important to remove acetylcholine from its binding to acetylcholine receptors once the neural stimulus ends? What can be the possible consequence of the non-removal of acetylcholine to the skeletal muscle fiber?
Both the withdrawal reflex and the Golgi tendon reflex involve sensory signals that ultimately control the same type ofmotor neurons and both are protective. Explain how one reflex can cause muscle contraction while the other causes musclerelaxation.
The disease poliomyelitis (po′le-o-mi′˘e-li′tis) destroys motor neurons, causingloss of muscle function and even flaccid paralysis. Some patients recoverbecause axon branches form from the remaining motor neurons. Thesebranches innervate the paralyzed muscle fibers to produce motor unitswith many more muscle fibers than usual. How does this reinnervation ofmuscle fibers affect the degree of muscle control in a person who hasrecovered from poliomyelitis?
A muscle cell contains acetylcholine receptors that act as ligand-gated cation channels,and it also contains voltage-gated Na+ channels of the type found in neurons. Intheory, could a muscle cell get away with having only acetylcholine-gated cationchannels, which would serve the dual purpose of receiving neurotransmitter signalsand propagating action potentials? Why or why not?
Predict the consequence if presynaptic action potentials in an axonrelease insufficient acetylcholine to depolarize a skeletal muscle fiber tothreshold.
Neuromuscular Junction: -Activation of nicotinic ACh receptors in the motor end plate results in both Na+ influx into and K+ efflux from the muscle fiber - An action potential in a motor neuron always produces a graded depolarization in the motor endplate and an action potential in the sarcolemma. -Acetylcholine released from the motor presynaptic terminal binds to voltage-gated ACh receptors in the motor endplate. -all of the above -a and b are right
In the rare neuromuscular disorder Myasthenia Gravis, autoantibodies are produced which inhibit acetylcholine receptor (nicotinic receptor) activity. Explain how inhibition of acetylcholine receptor activity at the neuromuscular junction will affect the sequence of events in muscular excitation and contraction in response to stimuli, and muscle function? (Mention the effects on all the significant events involved in excitation and contraction of muscles, and how it would affect muscle function).
In your own words, describe the main events occurring between the arrivalof an action potential at a motor neuron end plate and contraction of thecorresponding muscle. Use 250 words or less.
