Term
dendrites
Definition
receive messages from other cells.

people behind soma with arms out as dendrites.
Term
excitatory effect
Definition
more likely that the receiving neuron will generate an action potential or fire.

Send on the message, doooo it.
Term
sensory nerves
Definition
carry information from the sense receptors to the spinal cord and brain.

Just said that it was a sensory nerve.
Term
soma
Definition
cell body of a neuron, contains nucleus and other parts that keep the cell healthy.

Jaden was soma, with dendrites behind her.
Term
action potential
Definition
a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory.

sent with message down axon.
Term
synapse
Definition
a structure that permits a neuron or nerve cell to pass an electrical or chemical signal to another cell.

Someone was in the way of passing on the message, stood in between who had the message and who was going to get it.
Term
inhibitory effect
Definition
less likely that the receiving neuron will generate an action potential or fire.

don't do it.
Term
receptor cells
Definition
cells that turn senses into impulses.

Showed light to receptor cell to make it react.
Term
interneurons
Definition
nerve cells in the brain and spinal cord responsible for processing information.

said it. got paper from sensory nerves.
Term
axon
Definition
The extension of a neuron through which neural impulses are sent.

Soma sent the message down the axon with an action potential.
Term
axon terminals
Definition
The end point of a neuron where the neurotransmitters are stored.

Message sent down to this and stored here.
Term
refractory period
Definition
recharging of a neuron before it can send another signal.

how often the message can be sent.
Term
neurotransmitter
Definition
carry information across synapse

was given message from who had the message and gave it to the next person through the synapse.
Term
Motor nerve
Definition
carry information away from brain/spinal cord to the muscles/glands.

get new message from interneurons and send it to tell muscles and glands what to do.
Term
Neuron
Definition
Processes and transmits information through electrical and chemical signals.

A receptor cell that transfers the 5 senses into impulses.
