Neurons

Question 1

Axon: A stem-like protrusion

Answer 1

Carry electrical impulses that are the means of communication within the brain and between the brain and the rest of the body.

Question 2

Dendrite: Branch-looking structures attached to the edges of the neuron

Answer 2

Collects and stores all incoming information from axon terminal

Question 3

Soma: The body

Answer 3

Contains the nucleus and other structures common to living cells

Question 4

Gilal Cells: Web-looking

Answer 4

A type of cell that provides physical and chemical support to neurons and maintain their environment

Question 5

Myelin Sheath: Pencil cushion

Answer 5

The small, fatty, gilal protectors of the axon spine.

Question 6

Terminal Buttons: Small nubs at the end of axon

Answer 6

Found at the end of the axon, they carry signals across the synapse to other neurons.

Question 7

Neurotransmitters: Very small

Answer 7

They carry chemical signals from one neuron to the next target cell

Question 8

A Synapse: The gap between neurons (broad)

Answer 8

The places where neurons “connect” and communicate with each other

Question 9

Synaptic Cleft: The gap between two neurons (20nm)

Answer 9

Allows nerve impulses to pass from one neuron to the other

Question 10

Presynaptic Neuron: #1

Answer 10

The transmitter– what sends the signal

Question 11

Postsynaptic Neuron: #2

Answer 11

The receiver– what gets and then stores the signal

Question 12

Receptor Sites: Literally everywhere

Answer 12

Proteins which are able to recognize and bond to specific messenger molecules.
