A motor unit consists of <u>a single motor neuron</u>.
<h3>What is a motor unit?</h3>
Most mature extrafusal skeletal muscle fibers in mammals are innervated by only a single alpha motor neuron. Since there are more muscle fibers by far than motor neurons, individual motor axons branch within muscles to synapse on many different fibers that are typically distributed over a relatively wide area within the muscle, presumably to ensure that the contractile force of the motor unit is spread evenly .
In addition, this arrangement reduces the chance that damage to one or a few alpha motor neurons will significantly alter a muscle's action. Because an action potential generated by a motor neuron normally brings to threshold all of the muscle fibers it contacts, a single alpha motor neuron and its associated muscle fibers together constitute the smallest unit of force that can be activated to produce movement.
Sherrington was the first to recognize this fundamental relationship between an alpha motor neuron and the muscle fibers it innervates, for which he coined the term motor unit.

Answer:
sunlight hits the Earth most directly at the Equator. The curve of the Earth means that sunlight is spread over a wider area the further you move from the Equator. Sunlight hits a smaller surface area at the Equator so heats up quickly compared to the poles.
Answer:
CAT ATG TAC
Explanation:
Adenine (A) pairs with Thymine (T)
Cytosine (C) pairs with Guanine (G)
And vice-versa
Answer:
Option-B
Explanation:
Dysentery is an abnormal condition that is caused by the infection of the intestine in humans. The infection could be caused by the bacteria or the amoeba.
The disease can be characterized by the cramps in the stomach, diarrhea, and the loss of blood through feces.
Untreated dysentery can lead to the loss of a large amount of blood through feces and will lower the amount of blood in humans.
This severe loss of blood will give rise to another disease called hypovolemic shock is which the heart fails to pump enough blood to the organs due to which the other organs of the body can fail to work properly. This condition can lead to death.
Thus, Option-B is correct.
