Interneurons

serves as the connection between motor and sensory neurons; found almost entirely in the central nervous system

sensory neurons

conducts impulses from sensory receptors to the central nervous system (also called afferent neurons)

Motor neurons

conducts impulses from the central nervous system to cells in the body (also called efferent neurons)

Nature

• Biological

• Traits you inherited through genetics

Nurture

• Environmental

• Traits shaped by how your parents raised you

Motor neurons

Nerve cells that direct muscles and glands are known as

sensory neurons

Nerve cells that carry information (pain, temperature, etc.) from the body to the brain are called

Interneurons

serve as a connection between sensory neurons and motor neurons.

Central

These neurons exist solely in the central → nervous

system.

Glial cells

Supporting cells for neurons that are essential for the structural integrity of the nervous system and for the normal functioning of the neurons are called

Involuntary

Your autonomic nervous controls involuntary activities, such as breathing, heart rate and digestion. You can think of this system as having two settings - the default rest option) and the stress response option.

Sympathetic

When you are frightened by a sudden noise, the sympathetic nervous system kicks in and triggers your fight-or-flight response to help you prepare to handle the

emergency.

Parasympathetic

Once the emergency is over, your parasympathetic nervous system returns your body to its normal, restful state.

Lesioning

Purposefully damages

fMri

checks blood flow

EEG

electrical activity

somatic

nervous system controls voluntary muscle activity i.e. activating your leg muscles so you can kick a ball.

Central

nervous system consists of your brain and spinal cord.

autonomic

nervous system controls automatic functions like breathing and heart rate.

peripheral

nervous system consists of all the neurons outside of the brain and spinal cord.
