1
Q

What is the difference neurons and glia?

A

Neurons, receive and transmit information to other cells.
Glia, support cell (structurally and functionally!)
Waste management
Provide insulation (i.e., myelin sheath)
10 times more numerous than neurons but 1/10 the size

Q

Neuron structure: thin fiber of constant diameter, in most cases longer than the dendrites.

A

Axon

17
Q

Neuron structure: What are the functions of the Axon?

A

sends information from cell body to the pre-synaptic terminals to communicate with other neurons, glands, or muscles.

18
Q

Neuron structure: Axons are in most cases longer than the __________

A

dendrites

19
Q

Neuron structure: _______ are in most cases longer than the dendrites

A

Axons

20
Q

Neuron structure: An axon sends information from ___ _____ to the pre-synaptic terminals to communicate with other neurons, glands, or muscles.

A

cell body

21
Q

Neuron structure: An axon sends information from cell body to the ____-________ terminals to communicate with other neurons, glands, or muscles.

A

pre-synaptic

22
Q

Neuron structure: An axon sends information from cell body to the pre-synaptic terminals to _____________ with other neurons, glands, or muscles.

A

communicate

23
Q

Neuron structure: An axon sends information from cell body to the pre-synaptic terminals to communicate with other ________, ______, or ________.

A

neurons
glands
muscles

24
Q

Neuron structure: A neuron can have many _________ but only one ______.

A

dendrites

axon

25
Q

True or False:

Neuron structure: There CAN be many branches off of the axon.

A

True

26
Q

Neuron structure: There CAN be many _________ off of the axon.

A

branches

27
Q

Neuron structure: What is the difference between the presynaptic terminal and the postsynaptic terminal?

A

The presynaptic terminal is the end point of the axon that releases neuro-chemicals (i.e., neurotransmitter).
The postsynaptic terminal is the the dendrite on the receiving cell, contains receptor sites that neurotransmitter can bind to..

28
Q

Neuron structure: insulating material covering axons in many neurons; speeds up communication along the axon.

A

Myelin sheath

29
Q

The myelin sheath covers what section of a neuron?

A

it covers the axon

30
Q

Is a myelin sheath a good thing or a bad thing? Why?

A

It is good, because it speeds up communication along the axon

31
Q

What is a synaptic cleft?

A

the gap between Neurons

32
Q

neurotransmitters travel through the ________ _______

A

synaptic cleft

33
Q

little sacs filled with neurotransmitters

A

vesicles
