5. State the functions of the following :

(a)  Synapse                          (b)  Association neuron

(c)  Medullary sheath            (d)  Medulla oblongata

(e)   Cerebellum                    (f)    Cerebrospinal fluid

Dear student,

(a) Synapse: It is a gap between the axon terminal of one neuron and the dendrites of the adjacent neuron. It transmits nerve impulse from one neuron to another neuron.
(b) Association Neuron: It interconnects sensory and motor neurons.
(c) Medullary sheath: It provides insulation and prevents mixing of impulses in the adjacent axons.
(d) Medulla Oblongata: It controls activities of internal organs such as peristalsis, breathing and many other involuntary actions.
(e) Cerebellum: It maintains balance of the body and coordinates muscular activity.
(f) Cerebrospinal Fluid: It acts like a cushion and protects the brain from shocks.

Regards.

A medullary sheath is a protective covering surrounding and insulating certain nerve fibres. Medullary sheath is further composed of two layers; an inner fatty layer called the myelin sheath and an outside cellular layer called the neurilemma or sheath of Schwann cells. ?It is essential for the proper?. Hope it helps u !!
