Dendrites

________ are the part of a neuron that is tree- like or "branchy.

Lack of Dopamine

________ leads to Parkinsons disease.

Gilla cells

________ hold neurons in place.

ability of neurons

The ________ to grow back after injury or damage.

ACH

motor movement

Action potential

when neuron fires all or nothing firing

Somatic

Connects our sensory receptors to the skeletal muscles that allow voluntary movement

Somatic

When a bug lands on your arm you swat it

Automatic

Regulates internal organs

Automatic

When you are nervous your glands may produce sweat

Sympathetic

Mobilized bodily resources that increase energy

Parasympathetic

It operates during relaxed states and conserves energy

Synapse

space between neurons

DAN'S EGG

Dopamine, acetylcholine, norepinephrine, serotonin, endorphins, glutamine, GABA

Dopamine

alertness motor movement

ACH

motor movement

GABA

Inhibiting

GABA

Regulates amount of neurotransmitters that should be involved in the reuptake process

GABA

Slows down information

Action potential

when neuron fires all or nothing firing

Glutamate

A major excitatory neurotransmitter

Glutamate

Sparks neurotransmitter to allow transmission to continue

Serotonin

Neurotransmitter that is targeted by doctors for depression

Neural regeneration

The ability of neurons to grow back after injury or damage

Stem cells

Immature cells that renew themselves and have the potential to develop into mature cells

Afferent

Sensory neurons

Afferent

Receive info Outside back in to CNS

Efferent

Motor neurons

Efferent
