NEET PG DENTAL EXAM

Detailed explanation-1: -A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.

Detailed explanation-2: -Dendrites resemble the branches of a tree as they extend from the soma. The dendrites for a single neuron are collectively called the dendritic tree, and each branch is called a dendritic branch. Dendrites have a wide variety of shapes and sizes, and are used to help classify groups of neurons.

Detailed explanation-3: -Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron.

Detailed explanation-4: -Dendrites are structures which carry impulses towards the cell body of the neuron. A neuron may have multiple dendrites, but only one axon. The axon is a structure which carries impulses away from the cell body of the neuron.
