Neurons

Question 1

the fundamental unit of the nervous system, responsible for receiving, processing, and transmitting information through electrical and chemical signals.

Answer 1

Neurons

Question 2

neurons are specialized for carrying information throughout the body

Answer 2

Information transmission

Question 3

they receive sensory information from the external world and send it to the brain

Answer 3

Sensory Input

Question 4

They relay motor commands from the brain to muscles

Answer 4

Motor Commands

Question 5

The coordinated interactions of neurons enable complex brain functions like learning, memory, thinking, and emotion

Answer 5

Complex Functions

Question 6

tree-like branches that receive signals
(neurotransmitters) from other neurons

Answer 6

Dendrites

Question 7

the metabolic center of the cell, containing the nucleus and integrating signals from the dendrites

Answer 7

cell body (soma)

Question 8

area where signals are integrated; if strong enough, an action potential is initiated.

Answer 8

Axon hillock

Question 9

a long projection that conducts electrical signals (action potential) away from the cell body.

Answer 9

Axon

Question 10

A fatty insulation that wraps around many axons, speeding up signal transmission

Answer 10

Myelin

Question 11

Branches at the end of the axon that release neurotransmitters in the synapse to signal the next neuron

Answer 11

Axon terminals
