Answer» (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. |
