Receive impulses from
previous neuron
Short and highly branched
dendrites
Lipid layer
Where the axon joins
the cell body
axon hillock
Insulates the axon
Speeds up the transmission of
action potentials along the axon
myelin sheath
Gaps in the myelin sheath
along the axon
Impulses “skip” to them
Store neurotransmitters
that are released into the
synapse due to impulses

Neuron
Anatomy
nucleus
cell body
Schwann cells
Also known as the soma
Contains organelles
Produces proteins and
molecules needed for a neuron
to send/receive an impulse
Produce the myelin
sheath in the peripheral
nervous system
Carries impulses away
from the soma and
toward the next neuron
Fine projections at the end
of an axon that pass the
impulse to the next neuron
