What signal does the IIA afferent send? It signals the alpha motor neuron to contract the extrafusal muscle fibers

Muscle spindle structures consist of:     Extrafusal muscle fibers and gamma motor neurons     Extrafusal muscle fibers and alpha motor neurons     Golgi tendon organs and gamma motor neurons     Intrafusal muscle fibers and gamma motor neurons

Please answer asap and in short Explain why this statement is true or false

Which type of proprioreceptor is sensitive to changes in both muscle length and the speed of muscle contraction? Question 8 options:   golgi tendon organs   muscle spindles   pacinian corpuscle   end organs of Ruffini

Acetylcholine molecules are actively transported from the axon to their receptors on the muscle membrane by special transport proteins.

What is the micro anatomical arrangement of a skeletal muscle fiber cell?

Choose the type of information that the soft organ smooth muscle first order neuron are sending to the central nervous system: 1, sterogotic information  2, stretch information 3, proprioceptive information 4, temperature information This is the second time in 10 min I asked this question, the fomer one been rejected due to incompleted. But this is the whole inforamtion I had copied from my home work, no letter missed.

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?

Can you help me the name of the all of the number of the label muscle system model?

The central ends of afferents from muscle spindles synapse with all the following types of neurons, except :-a- α-motor neurons of the same muscleb- γ-motor neurons of the same musclec- local interneuronsd- 2nd order neurons of ascending sensory pathways
