Name THREE Functional parts of a neuron
1- cell body (soma) 2- dendrites 3- axon 4- myelin sheaths 5- axon terminals 6- nodes of ranvier
What structure functions like a highway and transmits nerve impulses from the body to the brain and from the brain to the body?
The spinal cord
What does a dendrite do?
Receives neurotransmitters from another neuron's axon terminal

The central nervous system is made of these organs
brain and spinal cord
What is the main difference between gray matter and white matter in the spinal cord?
Gray matter processes information and controls reflexes, while white matter transmits signals between different parts of the nervous system.
What are two key functions of the temporal lobe?
Processing auditory information (sound) and memory formation
What purpose is the purpose of the Myelin Sheath on an axon?
to speed up nerve impulses
Neurons taking information back to your body are called what?
motor neurons/Efferent neurons
An action potential travels along this structure until it reaches the axon terminal
the Axon
Name two functions of the midbrain.
The midbrain processes visual and auditory reflexes and helps regulate movement.
What part of the brain helps us understand speech and language?
The temporal lobe helps with understanding speech and language.
Which part of the brain processes sensory information such as pain and touch?
The parietal lobe processes sensory information such as pain, touch, and temperature.
Explain a Reflex Arc
sensory impulse in to spinal cord
In response, an efferent signal is sent via a motor nerve to move the body to keep it safe.
This process bypasses the brain first...
Sends the signal to the brain after sending the motor signal to move
