Really creative? You may want to thank this part of the brain.

What is the cerebral cortex?

100

This part of the neuron is responsible for interpreting the signal and determining whether or not it should continue.

What is the cell body?

100

Sodium channels are in charge! They are considered this type of channel.

What are voltage gated?

100

Can't hurt these animals feelings, mostly because they have no nerves and very little response to the environment.

What are sponges?

100

The voluntary part of the peripheral nervous system is known as this.

What is the somatic system?

200

A throwback to the endocrine system, this part controls hunger, thirst, pain, etc.

What is the hypothalamus?

200

This part of the neuron receives the signal.

What is the dendrite?

200

-70mV is considered this; it is because the outside of the membrane has a lot of sodium.

What is the resting potential?

200

Humans have this which consists of the brain and spinal cord.

What is a central nervous system?

200

If you did your portfolio, you know that this nervous system is the "return to baseline" system.

What is the parasympathetic nervous system?

300

Feeling off balance? This might be to blame!

What is the cerebellum?

300

A nerve impulse is called this.

What is an action potential?

300

This part of an action potential is when there is a huge spike in positivity in the membrane.

What is depolarization?

300

Cnidarian have this which is essential a network of cells.

What is a nerve net?

300

This part of the spinal cord contains cell bodies of motor neurons.

What is the ventral horn?

400

If this part of your brain stops working, you're cooked because it controls the vital functions of your body.

What is your medulla oblongata?

400

Myelin is formed by these cells.

What are glial cells?

400

Epic fail. Sometimes an action potential isn't created because neurons fire with this method.

What is the all or nothing method?

400

These creepy crawlers have specialized senses that include better senses of sight and hearing.

What are arthropods?

400

The synapse and the target cell together are collectively called this.

What is the synaptic cleft?

500

This is a relay center for cortical fibers.

What is the pons?

500

These gaps exist between myelin to allow the signal to jump the myelinated areas (and therefore move faster)

What are nodes of Ranvier?

500

This enzyme is crucial to help pump sodium and potassium back to their natural resting state.

What is ATPase?

500

These animals had the first primitive sign of a nervous system that consists of a nerve cord and a "brain"

What are annelids?

500

This is the process by which nerve impulses "jump" between the gaps in the myelin sheath of myelinated axons

What is saltatory conduction?
