Question

Explain the pros and cons of non divisible characteristic of the excitable cells?

Answer 1

Answer:

Explanation:

B) Nissl bodies- It is a large granular body found in the neuron cells.

C) Glial cells- These cells are the helper/supportive cells in the central nervous system. They do not help in conducting electrical impulses but are the most abundant cell type in the central nervous system. These glial cells surround the neurons and provide insulation between two neurons. They are most abundant cell types in the central nervous system. There are many types of glial cells which are oligodendrocytes, astrocytes (star-shaped),etc.

D) Schwann cell- They are present in the axon of a neuron. They help in supporting nerve regeneration

Thus the correct answer is 'Glial cells'.

Answer 2

Explanation:

Answer is option A i.e. "Glial cells"

Glial cells- These cells are the helper cells in the central nervous system. They surround the neurons and provide insulation between two neurons. There are variously shaped like oligodendrocytes, astrocytes (star-shaped), ependymal etc.

Dendrites- They are branched extensions of nerve cells.

Nissl bodies- It is a large granular body found in the neuron cells.

Nodes of Ranvier are gaps in the myelin sheath of axons.

Thus the correct answer is "Glial cells"
