12. Describe the basic structure of a neuron and know which parts of the neuron function to receive information, conduct action potentials, and transmit signals to other neurons or effector cells.

Cell body:

Creates action potential and sends it down a axon.

Cell body

What integrates information from several dendrites and holds a nucleus & organelles

Axon hillock:

cone-shaped elevation on axon (where cell body meets with axon)

Endoneurium:

covers each axon

Perineurium:

covers each fascicle

Epineurium:

covers entire nerve (bundles of fascicles)

Axoplasm:

cytoplasm of axon

Node of Ranvier:

places where AP jumps and increases speed of conduction

Axolemma:

plasma membrane of axon

Dendrites:

receive information & bring it towards cell body

Axon:

send information away from cell body
