UPDATE
Dendrites - what do they look like
Short, tapering, slightly branched structures extending from the body of the cell.
Dendrites - what do they consist of
Contain receptor sites
Dendrites - what is the function
Receive input from cells. Contact other neurons. Conduct impulses toward the cell
body.
(Imagine they're like a telephone tower receiving messages)
Axons - what do they look like
Long, thin projection that joins the cell body at the axon hillcock.
Position of Initial Segment
Adjacent to axon hillcock
Position of Trigger Zone
Junction of axon hillcock and initial segment
Position of Axon Terminals
Fine processes at end of axon
, Position of Synaptic Bulb
Bulb, shaped structures at the end of axon terminal
Function of sensory (afferent) neuron
Conveys information to the CNS
(receives information from your senses from the outside world and sends it to your
brain)
Function of motor (efferent) neuron
Convey information away from the CNS
(brain sends the information received from the sensory neuron to other parts of the body
to make it move/do what it needs to do in response)
Function of Interneuron (association) neuron
Integrate sensory information and activate motor neurons
(acts as a middleman that integrates sensory information and activates the motor
neurons)
What is a Ganglion? (neuronal bodies)
a cluster of cell bodies in PNS
What is a Nucleus (neuronal bodies)
a cluster of cell bodies in CNS
What is a Bundle? (neuronal bodies)
