E) enzymes fore degrading neurotransmitter. 9) The site of communication between two neurons is called a A) Nissl body. B) synapse C) varicosity D) dendrite. E) 10) All are correct.

Explanation / Answer

Ans 1....axolemma is

Plasma membrane

Axolemma is the term that used for plasma memnmemb of a neuron.it.surrounds the neueon being its outermost covering

Ans 8...nissals bodies

Are clustered of rough endoplasmic reticulum in cell body.

They have rostte of free ribosomes and are site of protein synthesis

Ans 9...synaptic vesicles store

Neurons transimittor

Synaptic vesicles under the effect of calcium ion fuse with axolemma and release the contained neurons transmitter in the synaptic cleft.

10.....site of communication between two.neuron is

Synapse

Synapse is the gap between two neurons where the two neurons interact by either electrical or chemical impulses called neurons transmitter.
