This is bundle of axons

What is a neuron?

100
Cranial nerves responsible for hearing or equilibrium
What is Auditory
100
The brain and the spinal cord make up which division of the nervous system?
What is Central Nervous System
100

The mV of resting potential

What is -70

100

This neuron type detects stimuli from the senses

What is afferent (sensory)
200

Conduct impulses toward the cell body

What is dendrite

200
Cranial nerve responsible for movement of the tongue.
What is hypoglossal
200

All nerves outside of the CNS are part of what division of the nervous system?

What is Peripheral Nervous System

200

What causes an action potential? (neg to pos OR pos to neg)

Neg to Pos charge WITHIN neuron

200
This is the main excitatory neurotransmitter in the brain; important for long-term memory

What is glutamate?

300
Conducts impulses away from the cell body
What is axon
300
What nerves carry motor impulses from the CNS to muscle fibers or glands?
What is motor nerves
300

The 2 divisions of the peripheral nervous system

What is Somatic & Autonomic

300

What ion enters the neuron to cause depolarization?

Na+

300

This is the brain's reward system; important in mood, motivation and addiction

What is dopamine?

400

These glial cells create myelin sheath in PNS.

What is Schwann cell?

400
This is the spinal plexus that supplies the arm, forearm and hand.

What is brachial?

400

Sensory neurons are part of this division in the PNS

What is Somatic?

400

This neuron shape makes up most all of CNS. (multi, bi or unipolar)

What is multipolar?

400

Gaps between myelin sheath; allows for transmission of signals along the axon.

What are Nodes of Ranvier

500
When impulse jumps across gaps in myelin sheath

What is saltatory conduction?

500

Which cranial nerve has primary control of the parasympathetic NS?

What is vagus nerve

500
What are the two divisions of the Autonomic Nervous System?
What are the Sympathetic & Parasympathetic Divisions?
500

This reflex type is initiated when you grab a harmful stimulus.

What is withdrawal?

500

This neuron transmits impulses from CNS to muscle or glands 

What is motor (efferent)?
