Question

Nervous tissue is made up of neutrons and neutroglial cells. Which of the following statements about these two cells is/are false ?
(i) Neuroglia make up more than one-half the volume of neutral tissue in our body
(ii) Neuroglia protect and support neurons
(iii) When a neuron is suitaly stimulated, an electrical disturbance is generated which swiftly travels along its cytosol
(iv) Arrival of the disturbance at the neuron\'s endings triggers stimulation or inhibition of adjacent neurons or other cells.

Answer 1

ANSWER

Neuroglias are cells in the central nervous system and the peripheral nervous system.

Along with neurons, they comprise the two types of cells in nervous tissue, and are integral to the functioning of the CNS and PNS.

Neuroglias play the role of supportive cells to neurons, which are responsible for all nervous system functions.

When a neuron is suitably stimulated, an electrical disturbance is generated which swiftly travels along its plasma membrane.

Arrival of the electrical impulse or stimulus at the nerve endings or output zone triggers events that may cause stimulation or inhibition of adjacent neurons and other cells.

So the correct option is C.
