Vedclass · Answer

(A) neuron is the structural and functional unit of the neural system. It consists of three major parts: $1$. Cell body (Cyton/Soma) $2$. Dendrites (represented as $a$) $3$. Axon (represented as $b$) Options $c$ (sarcolemma) and $d$ (neurilemma) are not parts of the neuron structure itself. Sarcolemma is the plasma membrane of a muscle fiber,and neurilemma is the outermost nucleated cytoplasmic layer of Schwann cells. Therefore,the neuron consists of dendrites and an axon. The correct option is $A$.

List $- I$	List $- II$
$a$. Multipolar neuron	$i$. Somatic neural system
$b$. Bipolar neuron	$ii$. Cerebral cortex
$c$. Myelinated nerve fibre	$iii$. Retina of eye
