17
Q

Adrenal glands

A

produce hormones
fight or flight responds to stress by sending message to release hormones

18
Q

Pituitary gland

A

“master gland” of endocrine system, produces growth hormone and regulates glands

19
Q

Endocrine System

A

Sends molecules as messages through blood
hormones go to brain and tissue

20
Q

Lesions

A

study brain by intentional surgical destruction of brain tissue

21
Q

Split brain

A

study by observing connections between hemispheres cut

22
Q

EEG (electroencephalogram)

A

recording of electrical waves sweeping across brain surface

23
Q

PET (position emission tomography)

A

See what part of the brain is active

24
Q

MRI (magnetic resonance imaging)

A

Images from signal produced by brain tissue (structures)

25
Q

functional mri

A

brain activity and function

26
Q

Brainstem and cerebellum

A

coordinates the body
balance coordination and motor functions

27
Q

Limbic (border) system

A

manage emotions and connect thoughts to body
Basic needs
F f’s
feeding forgetting fighting fornicating and forgetting

28
Q

Cortex

A

integrates information

29
Q

Medulla

A

controls base functions like heartbeat and breathing
Olympic athletes wear medals that cover their heart and lungs

30
Q

Pons

A

Coordinate automatic and unconscious movement
ponds are relaxing, relaxing is unconscious

31
Q

Thalamus

A

Sensory router, all senses except smell
Thal and amus are traffic directors

32
Q

Reticular formation

A

Nerve network in the brain stem
“tickle” alertness and motivation

33
Q

Cerebellum

A

Coordinate voluntary movement, nonverbal learning and memory

34
Q

Limbic system

A

Fear and aggression, basic drives, and formation of episodic memories above brain stem
Basic needs
F f’s
feeding forgetting fighting fornicating and forgetting

35
Q

Hippocampus

A

Process conscious, episodic memories, works with amygdala to form emotionally charged memories
Hippo lost on campus (cant remember)

36
Q

Amygdala

A

helps process emotions like fear and aggression.
The rest of the brain is a wig and its spooky

37
Q

Hypothalamus

A

Regulates body temp and ensures adequate food and water intake, directs endocrine system via messages to pituitary
Hypo -> hypothermia
survival

38

A

Outer part that coats the brain grey
inner white axons link brain
feed and protect neurons
“cereal court” complex thinking

39
