The Central Nervous System is?

The brain and spinal cord

The Peripheral Nervous System?

sensory and motor neurons

What two divisions can the PNS be divided into?

Autonomic nervous system and somatic nervous system

The autonomic system controls?

Visceral organs

The somatic system controls?

Involuntary and voluntary muscle movements

Sympathetic is?

Fight, Flee, or freeze

parasympathetic is?

rest and digest

What part of the neuron is this?

dendrite

What part of the neuron is this?

cell body or soma

What part of the neuron is this?

Axon

sensory neurons flow..

Afferent

Motor neurons flow…

Efferent

interneurons connect…

sensory to motor

Interoceptors Receive…

internal sensory info for pain, deep pressure respiartory, and cardiovascualr.

Proprioceptors receive…

internal sensory info of skeletal muscles

Exteroceptors receive..

External sensory info of touch, temp, pressure, and special sensory

What glial cell is this and what does it do?

ependymal; this regulates CSF fluid and lines central canal

What glial cell is this and what does it do?

Astrocytes, makes the blood-brain barrier

What glial cell is this and what does it do?

Microglia; they eat pathogens and waste cells

What glial cell is this and what does it do?

Oligodendrocytes; they make myelin sheath to neurons (do NOT cover ALL neurons)

What glial cell is this and what does it do?

Satellite; regulate gases around neurons

What glial cell is this and what does it do?

Schwann cells; myelin sheath that covers ALL peripheral neurons (un-mylientated too)

Epinerium covers

The entire neuron

Perineurium covers

bundles of neurons

Endoneurium covers

individual axons
