Cerebellum

A

Below the temporal and orbital lobe. First part of brain effected by alcohol. Motor functions turn off but frontal lobe says you are okay because frontal lobe is not effected yet

Q

Superior frontal gyrus

A

Frontal lobe

  • working memory, 8-10 bits of info in 30 seconds. This is why # numbers are 9 #
  • executive processing - takes info and processes it
  • focusing, starting and stopping
  • special orientation

Auditory processing

17
Q

Middle temporal gyrus

A

Temporal lobe

Long term memory

18
Q

Inferior temporal gyrus

A

Temporal lobe

Number recognition, facial recognition

19
Q

Sulcus

A

Diving lines between loves
Central sulcus divides frontal and parietal lobe
Lateral sulcus divides parietal and temporal lobe

20
Q

Wernicke’s area

A

Temporal and parietal lobe. Left hemisphere

Understands language

21
Q

Central fissure

A

Divides right and left hemisphere

22
Q

Both hemisphere of the brain work together. What does this mean?

A

You need one part of brain to function with other side. EX: right hand of the body is controlled by left side of the brain.

23
Q

Broca

A

Frontal lobe

Responsible for producing language

24
Q

Fusiform gyrus

A

Located in the temporal gyrus

Facial recognition

25
Q

Left hemisphere of the brain

A

Broca controls talking

Wernicke controls listening

26
Q

3 parts of neuron

A
  • oligodendrocytes / Schwann cell
  • astrocytes
  • microglial
27
Q

Oligodendrocytes / Schwann cell

A

Makes neurons work longer and faster by producing myelin

28
Q

Nodes of ranvier

A

Found between myelin and action potential happens here

29
Q

Action potential

A

Sodium / potassium pump

Sodium goes in while potassium goes out. Potassium goes in while sodium goes out

30
Q

Astrocytes

A

Connect neurons and capillaries. Allow blood to flow

31
Q

Microglial cells

A

Eat dead neurons and process them away

32
Q

How many neurons on average does an adult brain have?

A

100 billion

33
Q

How do excess neurotransmitters get back into terminal bud?

A

Reuptake
