NERVOUS SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The part of the neuron that takes in and receives messages is called the ____
A
dendrite
B
nucleus
C
axon
D
synapse
Explanation: 

Detailed explanation-1: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential.

Detailed explanation-2: -Dendrites (from Greek déndron, “tree"), also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.

Detailed explanation-3: -Axon hillock: Once a signal is received by the dendrite, it then travels to the cell body. The cell body contains a specialized structure, the axon hillock that “integrates” signals from multiple synapses and serves as a junction between the cell body and an axon.

Detailed explanation-4: -Dendrites are the finger-like cells present on the end of a neuron. They are short, branching fibres extending from the cell body of the nerve cell. This fibre increases the surface area available for receiving incoming information. Dendrites are the receiving or input portions of a neuron.
