1

❌: Comprised of sensory neurons and motor neurons. Governs conscious brain sensing and response.
❌: - Unconscious or involuntary actions to stimuli. Automatic response to information.

Somatic

Autonomic

1

Each section of the NS is a collection of Neurons

1

What does every neuron have?

1

What are the three types of neurons?

1

❌ Carry messages from brain to target organs, tissues, or cells, to evoke a response to the stimulus (cause the body to react to information).

❌ Carry sensory information from the extremities and internal organs to the brain. Receive stimuli from environment and relay that info to the brain.

❌ Found in the CNS and link motor and sensory neurons. Commonly used in reflex arcs.

Sensory Neurons:

Motor Neurons:

Association Neurons:

1

Response of the NS is slow-acting and long-lasting

1

A reflex arc requires the brains coordination

Order the process of a reflex arc:

Arrival of stimulus
