Label Parts of a Neuron Diagram | Quizlet

Dendrites

receives impulses from other nerve cells

axon hillock

The cell body...the part of the cell that houses the nucleus and keeps the entire cell alive and functioning

Myelin Sheath

Surrounds the axon an insulates it from surrounding cells and tissues and making signal transitions faster and more efficient

Terminal Buttons

Release neurotransmitters

Neurotransmitters

The chemical signals that neurons use to communicate with other neurons and cells. It is the chemical involved in impulse transmission

Neuron transportation

Neurons generally transport signals in one direction from the dendrites, through the soma, along the axon and unto the terminal buttons

Nodes of Ranvier

Unmyelinated gaps in the myelin sheath that allows for movement of chemicals for impulse generation

Axon

A fiber attached to the soma that carries messages out to other cells and have little knobs on the end called terminal buttons

Soma

contains the genetic instructions for the function of the cell

soma

contains the genetic instructions for the function of the cell

axon hillock

joins the soma and axon to collect the impulses before sending one down the cell

myelin sheath

surrounds some neurons to increase how efficiently it can carry an impule

axon

carries the cell's impulse to the terminal

terminal

spreads the cell's impulse out to reach other neurons
