brain stuff again

parts of the limbic system

limbic system, hippocampus, amygdala, hypothalamus

parts of the forebrain

thalamus, hypothalamus, basal ganglia, limbic system, cerebral cortex, subcortical structures

midbrain

orientation and movement, contain textum and tegmentum

hindbrain

basic life functions, medulla, pons, reticular formation, cerebellum

the nervous system (4): interacting neurons that convey electrochemical signals through the body

central nervous system (cns), peripheral nervous system (pns), > pns, somatic nervous system + automatic nervous system> ans, sympathetic + parasympathetic

the nervous system (4): the nervous system

interacting neurons that convey electrochemical signals through the body

the nervous system (4): central nervous system (cns)

composed of brain and spine

the nervous system (4): peripheral nervous system (pns)

connects cns to the bodys organs and muscles

the nervous system (4): somatic nervous system

conveys info in and out of cns

the nervous system (4):automatic nervous system

carries involuntary and automatic commands to bloodvessels, organs, glands

the nervous system (4):sympathetic nervous system

prepares body for threats

the nervous system (4): parasympathetic nervous system

helps body return to resting state

the cerebral cortex (4) and what they do each

occipital lobe (visual info), parietal lobe (info about touch), temporal lobe ( hearing and language ), frontal lobe ( movement and abstract thinking)

components of a neuron :basic

cell body, dendrite, axon, mylein sheath, gilal cells, synpase

components of a neuron : cell body

info processing tasks, keeps cell alive

components of a neuron : dendrite

receives info from other neurons and relays it to cell body

components of a neuron :axon

transmits info to muscles, glands, other neurons

components of a neuron : mylein sheath

insulating layer of fatty material

components of a neuron : gilal cells

support cells found in nervous system

components of a neuron : synpase

region between axon of one neuron and dendrites/ cell body of another

3 major types of neurons (3)

sensory ( external world to brain and spine), motor neurons (spine to muscles to produce movement), interneurons ( connect sensory, motor and other interneurons)

Receptors

parts of the cell membrane that receive the neurotransmitter and initiate or prevent a new electric signal

neurotransmitters

chemical messengers

resting potiental

The difference in electric charge between the inside and outside of a neuron's cell membrane

action potiental

electric signal conducted along neurons axon to a synpase

hindbrain, basic life functions: the medulla

medulla: respiration,circulation and heart rate

hindbrain, basic life functions: reticular formation

regulates sleep, wakefulness and arousal

hindbrain, basic life functions: cerebellum

motor skills, sequences of movements, smooths actions

hindbrain, basic life functions: pons

relays info from cerebellum to rest of brain

midbrain, orientation and movement: tectum

orients in environment, receives stimuli from eyes, ears, skin

midbrain, orientation and movement: tegmentum

involved in movement, stimuli, arousal

forebrain, highest level of brain, for complex, cognitive and emotional sensory and motor functions: thalamus

relays messages to cerebral cortext, receives major senses except smell

forebrain, highest level of brain, for complex, cognitive and emotional sensory and motor functions: hypothalamus

regulates body temp, hunger, thirst, sexual behaviour, emotion and reward

forebrain, highest level of brain, for complex, cognitive and emotional sensory and motor functions: basal ganglia

set of subcortical structures that directs intentional movements

forebrain, highest level of brain, for complex, cognitive and emotional sensory and motor functions: pituitary gland

master gland of bodys hormone system, releases hormones that direct the functions of glands

THE LIMBIC SYSTEM 4:

1, limbic system, hypothalamus, hippocampus, amygdala

THE LIMBIC SYSTEM 4: limbic system

group of forebrain structures involved in motivation, emotion, learning, memory

THE LIMBIC SYSTEM 4: hypothalamus

regulates body temp, thirst, hunger, sexual behaviour

THE LIMBIC SYSTEM 4: hippocampus

memories and turning them into knowledge, learning

THE LIMBIC SYSTEM 4: amygdala

emotional memories and processing

forebrain: subcortical structures 4

thalamus, hypothalamus, basal ganglia, pituitary gland

Forebrain (cerebral cortex)

corpus callosum

the large band of neural fibers connecting the two brain hemispheres and carrying messages between them

somatosensory cortex

skin areas on contralateral surface of the body

the cerebral cortex

organization of specific lobes , sense and meaning
