NERVOUS SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The purpose of the Nerouns
A
Insulate the axon fibers increase rate of speed
B
Collect Stimuli
C
Transmit information in the form of nerve impulses through the body
D
None of the above
Explanation: 

Detailed explanation-1: -Neurons transmit information with the help of its dendrites, axon, soma and terminal buttons by converting stimuli into electrical impulses. This is done by the following method: Dendrites receive the incoming neural impulses, from adjacent neurons or directly from the sense organs, in electrochemical form.

Detailed explanation-2: -Sensory neurons carry nerve impulses from sense organs and internal organs to the central nervous system. Motor neurons carry nerve impulses from the central nervous system to organs, glands, and muscles-the opposite direction.

Detailed explanation-3: -The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized-that is, there is a difference in electrical charge between the outside and inside of the membrane.

Detailed explanation-4: -Neurons are responsible for sending and receiving neurotransmitters-chemicals that carry information between brain cells. Depending on its location, a neuron can perform the job of a sensory neuron, a motor neuron, or an interneuron, sending and receiving specific neurotransmitters.

Detailed explanation-5: -Neurons receive chemical input from other neurons through dendrites and communicate information to other cells through axons.
