Q

Cerebral Cortex

A

-outer layer of cerebrum

Q

2 Layers of cerebrum

A

Gray matter-outter layer, no myelin, Muscle control, sensory perception: seeing, hearing, memory, emotions and speech

White matter-fiber tracts deep to the gray matter, affects how the brain learns, communication between different parts of brain

Q

Thalamus

A

-Post office!
(info goes through thalamus and then is sent where it needs to go) NO SMELL
-“gateway” to cerebral cortex
-SORTING STATION for senses
…all senses go through thalamus and sends info from senses

16
Q

Hypothalamus

A

-HOMEOSTASIS
-control and regulation of less critical things like thirst and hunger…not an urgent need for these things.
-REWARD system
-Behavior, Body temp
-emotional response (limbic system)
-Pituitary gland (master gland) controls other glands

17
Q

Epithalamus

A

Sleep regulation/patterns
houses main endocrine glands:
-Pineal gland-secrets melatonin
-Choroid plexus-Helps form cerebrospinal fluid

18
Q

Ventricles

A

STORAGE of cerebrospinal fluid (cushioning)CNS
Protect brain and spinal cord (CNS)

19
Q

Meninges

A

Protective membrane around the brain
-Separates the brain from the skull
-house the ventricles

20
Q

Blood brain barrier

A

Wall of cells that stop things from getting into the brain!
-keep out harmful things except for a couple things: alcohol, nicotine, anesthesia, fats, and respiratory gases

21
Q

Corpus Callosum

A

Large relay between left and right hemispheres
-connects both sides of the brain; communication

22
Q

Optic Chiasm

A

area where optic nerves cross hemispheres

23
Q

cingulate gyrus

A

PAIN
-Shift between thoughts smoothly.
-Interprets pain/anger
-Motivation
_emotional response to pain
-regulates aggressive behavior

24
Q

Cerebellum

A

-The little brain
-Coordination; Movement; Balance

25
Q

Mid brain

A

-Fight or Flight
-reflex/muscle control
-Head/Eye movement

26
Q

Pons

A

Bridge between Mid brain and medulla oblongata
-connected to respiratory system
-Tells us to breathe, release oxygen, normal breathing

27
Q

Medulla Oblengata

A

-Ability to control vomit, coughing, sneezing
-Blood pressure and Heart rate
-Keeps us breathing
CRITICAL HOMEOSTASIS

28
Q

Basic actions brain takes to learn stuff (learning/Memory)

A

-sensory
-repetition(allows our neurons to strengthen/learn)
-consolidation(putting together)
-retrieval

29
Q

Amygdala

A

-In temporal lobe
-Fear (urbach-wiethe)
-Strong emotions (scared)(love)
-emotional trauma memories/memory association through emotion.

30
Q

Hippocampus

A

-Linking things together we already know
_elephants never forget(strong hippocampus)
-remembering a stupid thing we did knowing not to do it again at night.
-permanent memory how to do things

31
Q

Mammillary body

A

Smell that brings memories
-3 F’s: Food Friends Fornication (reproducation)

32
Q

Fornix

A

Carries signals from hippocampus to hypothalamus

33
Q

Neuro diversity

A

Concept that our brains are all different and that we learn in different ways (dislexia,autism)

34
Q

Pineal Gland

A

Produces melatonin wake/sleep patterns

35
Q

Pituitary gland

A

MASTER GLAND
produces
hormones that regulate homeostasis
ex… Growth, Blood pressure, Pain relief, Breast milk production
_it tells other glands when to do things/secrete their own hormones

36
Q

Neuro plasty

A

Ability to learn, relearn, unlearn and retain

37
Q

autonomic nerves 2 parts

A

sympathetic (fight or flight) and parasympathetic (rest and digest)

38
Q

somatic

A

afterent and efferent nevers
