A person met a leopard as he walked along the forest path and ran away immediately. Explain how the nervous and adrenal glands worked together to bring about the action observed.

Answer:

-Image of a leopard formed in the fovea stimulates in impulse; which is transmitted along the sensory neurone; to the grey matter/ central nervous system/ spinal cord; The chemical transmission of impulse is done across a synapse; to relay neurone; and through another synapse; to motor neurone; and across another synapse; to muscles/ effectors/ biceps muscles; the biceps muscles contract;
-At the same time the impulse is sent from the spinal cord; to the adrenal glands; which stimulates them to secrete adrenaline; which stimulates increase in heart beat and rate and amount of blood flowing the muscles to supply more blood to supply nutrients and oxygen for muscular contraction/ respiration; and remove metabolic wastes; it also stimulates the conversion of glycogen into glucose in the liver;
