Vedclass · Answer

(D) neuron is the structural and functional unit of the neural system. It consists of three major parts: the cell body (cyton),dendrites,and axon. $1$. Dendrites are short fibers that branch repeatedly and project out of the cell body; they transmit impulses towards the cell body. $2$. The axon is a long fiber,the distal end of which is branched into synaptic knobs called telodendria; it transmits nerve impulses away from the cell body to a synapse or to a neuro-muscular junction. $3$. Nissl's granules are present in the cell body and dendrites but are absent in the axon. $4$. Based on the number of axon and dendrites,neurons are divided into multipolar,bipolar,and unipolar,not apolar.
