17
Q

Two types of matter in the brain. What is white matter?

A

Fiber tracts of the cells as they connect to each other. White because it contains Myelin in

18
Q

Two types of matter in the brain. What is grey matter?

A

cell bodies and the dendrites. No Myelin

19
Q

What is the function of neurons?

A

Detect information from the environment e.g. visual information

Allow us to move and act

20
Q

What are sensory neurons?

A

Information is coming IN to them from light, sound, taste, odour, touch

21
Q

What are motor neurons?

A

Information is going OUT in order to control muscle actions

22
Q

What are interneurons?

A

Relay and process information between other neurons . They also process info and make sure information is as useful as it can be when it gets to other end.

23
Q

What do dendrities do?

A

Receive information from other cells (e.g. sensory cells or other neurons)

Dendrities is greek word for ‘tree’

24
Q

What does the axon do?

A

Passes messages away from the cell body to other neurons

25
Q

What are schwann cells?

A

They form the myelin sheath that protects the axon

26
Q

What are the axon terminals?

A

Forms junctions with other cells

27
Q

what is a soma?

A

cell body

28
Q

where are Axodendritic synapses found?

A

Axon to dendrite:

Where dendrites / axon terminals from two cells meet

29
Q

Where are axosomatic synapses found?

A

Axon to cell body (soma) of receiving neuron

30
Q

What are dendrodenditic synapses?

A

Where dendrites of two different neurons are in contact.

Capable of transmission in either direction.

31
Q

What are axoaxonic synpases?

A

Axon to axon

play a modulatory role (on/off)

32
Q

Cerebral cortex anatomy: What are the four lobes?

A

Frontal lobe
Parietal Lobe
Occipital lobe
Temporal Lobe

33
Q

What is the frontal lobe responsible for ?

A 
Frontal lobe.
Front of brain
-Decision making
-creativity
-impulse control
-higher order functions
34
Q

What is the parietal lobe responsible for

A

this is the motor quarter
lots of things here are integrated, so info coming in needs to be integrated with plans so we can create motor behaviours

35
Q

What is the occipital lobe for?

A

Vision

36
Q

What is the temporal lobe for

A

Interpreting facial expressions
Hearing
Smell
Language
