nervous system EVERYTHING

honestly probably better than the other ones because it was made closer to when i made the notes

consists of

brain

spinal cords

nerves

central nervous system

bodies command center

central nervous system

nervous system function: process info

central nervous system

nervous system function: motor responses

central nervous system

nervous system function: regulate body mechanisms

central nervous system

consists of: nerves distributed throughout body

peripheral nervous system

function: sensory info for CNS

peripheral system

contains: cerebrum

forebrain

splits into: hemispheres

forebrain

outer layer of forebrain is called

cortex

cortex is composed of

grey matter

is the cortex outer layer thick or thin

thin

what is the foundation of conscious experience

cortex

what happens if info does not reach the cortex layer

we are not conscious of it

function: where ANALYSIS of internal and external environment happens

association area

function: augment function of both primary motor and sensory cortex

association area

function: integrate past and present info for comparison

association area

function: responsible for memory and emotional aspects of behavior

limbic system

function: responsible fight or flight response

limbic system

function: responsible for planning reasoning and emotion

limbic system

these cortex are associated with which lobes : primary cortex

frontal lobe

these cortex are associated with which lobes : prefrontal cortex

frontal lobe

crucial for voluntary motor movements

primary motor cortex

where most cognitive function occurs

prefrontal cortex

these cortex are associated with which lobes : sensory cortex

parietal lobe

func: PROCESS internal and external stimuli (lobe and cortex )

parietal lobe

sensory cortex

these cortex are associated with which lobes : primary visual cortex

occipital lobe

which cortex and lobe is responsible for processing interpreting integrating visual stimuli

primary visual cortex

occipital lobe

these cortex are associated with which lobes : primary auditory cortex

temporal lobe

func: process auditory info (lobe and cortex)

primary auditory cortex

temporal lobe

func: speech comprehension (lobe and cortex)

temporal lobe

func: formation of long term memory (lobe and cortex)

temporal lobe

func: recognize emotions in language (lobe and cortex)

temporal lobe

which part of brain is this associated with: occipital lobe

forebrain

which part of brain is this associated with: association area

forebrain

which part of brain is this associated with: limbic system

forebrain

which part of brain is this associated with: frontal lobe

forebrain

which part of brain is this associated with: parietal lobe

forebrain

which part of brain is this associated with: occipital lobe

forebrain

which part of brain is this associated with: temporal lobe

forebrain

function(what part of brain): alertness

midbrain

function(what part of brain): sleep / wake cycle

midbrain

function(what part of brain): motor activities

midbrain

function(what part of brain): detect auditory and visual cues to initiate reflexes

midbrain

which part of brain is this associated with: cerebellum

hindbrain

which part of brain is this associated with: pons

hindbrain

which part of brain is this associated with: medulla oblongata

hindbrain

function: balance and movement coordination

cerebellum

what type of movement does the cerebellum coordinate (voluntary or involuntary)?

both

funct: transmits signals between

• forebrain and cerebellum

• brain and body

pons

funct: regulates breathing patterns and sleep cycles

pons

funct: regulates

• breathing

• blood pressure

• heart rate

• motor controls

medulla oblongata

what are the two types of nervous sytem

peripheral

central

what are the two types of peripheral nervous system

autonomic

somatic

PNS: involuntary

autonomic

PNS: responsibilities

• internal temp

autonomic

PNS: responsibilities

• GI function

autonomic

PNS: responsibilities

• excretory and endocrine system

autonomic

PNS: responsibilities

• motor function of skeletal muscle

somatic

PNS: cardiac muscle

autonomic

PNS: smooth muscle

autonomic

PNS: skeletal muscle

somatic

PNS: skeletal muscle

somatic

PNS: voluntary

somatic

what are the two types of autonomic nervous systems

sympathetic

parasympathetic

autonomic nervous systems: fight or flight response

sympathetic

autonomic nervous systems: increase heart rate and resting rate

sympathetic

autonomic nervous systems: slows digestion

sympathetic

autonomic nervous systems: rest and digest

parasympathetic

autonomic nervous systems: decrease heart rate

parasympathetic

autonomic nervous systems: digestion occurs

parasympathetic

neurons: receive signals from other cells

dendrites

neurons: carries info towards neuron cell body

dendrites

neurons: signals start here

dendrites

neurons: contains organelles and nucleus

cell body

neurons: made of fats and lipids

myelin

neurons: white in color

myelin

neurons: insulate axxon

myelin

neurons: nerve fiber

axon

neurons: carries impulse away from neuron cells body towards other cells

axon

neurons: releases chemical neurotransmitters into synapse

axon terminal

neurons: where neurons communcate with eachother

synapse

(white or grey matter) where signal transmisison takes place form one area of the brain to another like a highway

white matter

(white or grey matter) where info is integrated and processed

grey matter

funct: help hold neuron in place

glial

funct: sustain blood brain barrier

glial

funct: maintain chemical balance for signaling between cells

glial

funct: produce myelin sheath

glial

funct: generate cerebrospinal fluid

glial

funct: maintain homeostasis

glial

what are the two types of neuron input and output:

afferent

efferent

neuron input and output:

• sensory neuron input

afferent

neuron input and output: sensory input to CNS

afferent

neuron input and output: motor neuron output

efferent

neuron input and output: output away from CNS

efferent
