Front

The long, fiber like part of a neuron which the cell sends information to receiving neurons

Back

axon

Front

This releases neurotransmitters which are sent into the synaptic cleft for receptors on the dendrite to taste: axon, axon terminal, gene, neuron

Back

axon terminal

Front

A network of branches coming from individual cells.  They carry information and electrical signals in the brain and nervous system

Back

dendrite

Front

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

Back

myelin sheath

Front

A chemical produced by neurons that carries messages to other neurons

Back

neurotransmitter

Front

At resting potential, the ion distribution inside and outside of a neuron is such that __________ ions are most abundant on the outside of the cell, while __________ ions are most abundant on the inside of the cell.

Back

Sodium; potassium

What is structure labeled H in the picture?

Back

Node of Ranvier

Front

nerve impulse

Back

action potential

Reuptake is best defined as...

Back

reabsorption of excess neurotransmitter molecules by a sending neuron.
