16. Long answer question I

 

c. The cell bodyaxon is found in the grey matter of the brain’s central nervous system.

 

d. Cell body is also called axon or somacyton or soma.

 

e. The granular bodies found in the cell bodies are known as nissl's granulessecondary granules.

f. A single long, cylindrical conducting fibre extending from a neuron is known as an axoncyton.

 

g. Axon terminals are fragile hair-like structures. Each branch ends in a synaptic knob, which is a bulb-like structure. Synaptic vesicles, which contain substances known as neuroreceptorsneurotransmitters, are found in the synaptic knob.

 

h. Axons carry nerve impulses from the cell body to a neuromuscular junctionneurotransmittor junction.

 

i. The short branched, hair-like fibres of a neuron are called axonsdendrites.

 

j. In neurons, the golgi bodiescentrosome is absent.

 

k. The part of the neuron which transmits the impulse away from the cell body is Cell bodyAxon.

 

l. The part of the neuron which receive nerve impulse is AxonsDendrites.

 

m. Which one is helping the production of proteins in nerve cells? Cytoplasmic granules Nissl's granules.

 

n. Which one is helps in the formation of myelin sheath around the axon?

 

o. A bulb-like structure which contains neurotransmitter is called Myelin sheath Synaptic knob.
