Long threadlike part of the nerve cell that carries nerve impulses away from the body.

A short branched extension of a nerve cell that receive signals from the axon terminals.

A type of glial cell that surrounds neurons, keeping them alive and sometimes covering them with a myelin sheath.

An insulating layer that forms around the Schwann cells, allows electrical impulses to transmit quickly along the nerve cell.

A chemical messenger that carries signals from one neuron to the next cell.

The nucleus containing central part of a neuron, excluding its axon and dendrites.

The most distal portion of a neuron's axon that contains neurotransmitters and makes synaptic contact with other nurons.

The gaps in the myelin sheath of a nerve, between adjacent Schwann cells.

A molecule that relays signals at receptors on the cells surface to help neurotransmitters get from axon synapse to dendrite.

The space between the end of a nerve cell and another cell, it connects the nerves together at the end of axon terminals to dendrites.

A type of neurotransmitter and hormone that plays a role in movement, memory, pleasurable reward, and motivation.

A type of neurotransmitter and hormone that plays roles in mood, sleep, digestion, nausea, healing, bone health, and sexual desire.

saclike structures that store neurotransmitters before releasing them in response to an electrical signal within a cell.

Gets activated by neurotransmitters, when a neurotransmitter bumps into the right receptor, it will stick and do its function to the body.

Dendrite	A short branched extension of a nerve cell that receive signals from the axon terminals.
Schwann Cells	A type of glial cell that surrounds neurons, keeping them alive and sometimes covering them with a myelin sheath.
Myelin Sheath	An insulating layer that forms around the Schwann cells, allows electrical impulses to transmit quickly along the nerve cell.
Neurotransmitters	A chemical messenger that carries signals from one neuron to the next cell.
Cell Body	The nucleus containing central part of a neuron, excluding its axon and dendrites.
Axon Terminals	The most distal portion of a neuron's axon that contains neurotransmitters and makes synaptic contact with other nurons.
Node of Ranvier	The gaps in the myelin sheath of a nerve, between adjacent Schwann cells.
Secondary Messenger	A molecule that relays signals at receptors on the cells surface to help neurotransmitters get from axon synapse to dendrite.
Synapse	The space between the end of a nerve cell and another cell, it connects the nerves together at the end of axon terminals to dendrites.
