Which of the following part of a neuron is covered by fatty sheath?
1 Axon
2 Cyton
3 Dendrite
4 Node of Ranvier
Explanation:
A The axon of a neuron is covered by fatty sheath called as the myelin sheath. Myelin sheath is made up of Schwann cells which are present on the axon of a neuron. They wrap around the axon and form a myelin sheath, which helps to insulate the axon and speed up the conduction of nerve impulses.

Sympathetic nervous system induces
1 Heart beat
2 Secretion of digestive juice
3 Secretion of saliva
4 All of the above
Explanation:
A The sympathetic nervous system induces heart beat, secretion of saliva, and many other responses that prepare the body for a fight-or-flight response. The parasympathetic nervous system, is responsible for calming the body down and promoting digestion. It does this by slowing down the heart rate, relaxing the muscles and stimulating the secretion of digestive juice.
