Neurons in which dendritic and axonal processes are continuous and the soma lies off to one side are called.

Answers

The neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.

What is a unipolar neuron?

The neuron is the structural and functional unit of the nervous system, which when they have only a short projection that later branches into two or more branches, are considered unipolar.

That is, they are those neurons in which only one extension or neurite emerges from the soma, which will act as an axon and at the same time will have dendrites with which it can both receive and transmit information.

Therefore, we can conclude that the neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.

B.Skeletal muscle does not fatigue ; cardiac muscle is fatigues quickly. C.Skeletal muscle is involuntary ; cardiac muscle is voluntary. D.Skeletal muscle is fatigues. muscle does not.

Answers

D.Skeletal muscle is fatigues. muscle does not.

Skeletal muscle is striated muscle-essentially the fibers slide on each other to shorten and lengthen.
Cardiac muscle is a bit of a mish-mash. It is quite contractile and has striations like skeletal muscle, but also has discs within the structure which speed the contractile process

Skeletal muscle is voluntary and will not contract unless stimulated by a nerve fiber (or an electrode). Cardiac muscle is involuntary and contracts even without nervous stimulation.

D.Skeletal muscle gets fatigued while the cardiac muscle does not.
