brain parts and function

frontal lobe

primary motor cortex

B

premotor

broca’s area

prefrontal cortex

(not frontal lobe)

primary motor

motor control

premotor

learned motor skills, working memory spatial tasks

broca’s area

motor speech area

fronal lobe

executive area for task management, solving complex problems, multitasking

prefrontal cortex

personality

parietal lobe

temporal lobe

occipital lobe

brain stem

thalamus

midbrain

pons

blue

medulla oblongata

green

spinal cord

cerebellum

limbic system

what system is this?

hypothalamus

green

pituitary gland

yellow

pineal gland

amygdala

hippocampus

basal ganglia

gyri

surface folds of brain, increases surface area

sulci

dips of folds in brain, increases surface area

parietal lobe

processes sensory info from environment, mainly relating to touch, taste, and temperature.

temporal lobe

processes auditory information and encodes memory

occipital lobe

visual perception

brain stem

regulating most of the body’s automatic functions (breathing, heartbeat)

midbrain

vision, hearing, motor control, sleep/wake, alertness, and temperature regulation

pons

handles unconscious processes, sleep/wake cycle adn breathing.

medulla oblongata

helps with heartbeat, breathing, and blood pressure

spinal cord

sends motor commands from the brain to the body, sends sensory information from the body to the brain, coordinates reflexes

cerebellum

controls balance and movement

limbic structure

feeding, reproduction, maternal/paternal needs, fight/flight responses

hypothalamus

thermoregulation, regulation of food intake, regulation of body water content, center for autonomic nervous system, endocrine control, reproduction, circadian rhythm

pituitary gland

regulates growth, metabolism, and reproduction through the hormones it produces

pineal gland

receives information about the state of the light/dark cycle from the environment and conveys the info through the production of melatonin (hormone)

thalamus

body’s information relay system.

amygdala

fear/reward center

hippocampus

learning, memory encoding, memory consolidation, and spatial navigation. big for memory.

basal ganglia

motor control, motor learning, executive functions and behaviors, and emotions. controls body’s ability to move.

afferent divison

sensory stimuli and visceral stimuli go to which divison?

visceral stimuli

organ filling, bloating and distension, nausea. ex: hunger, fullness in rectum and bladder.

brain and spinal cord

parts of central nervous system

peripheral nervous system

the two divisions of this system are the afferent division and efferent division

efferent division

which division does information from the CNS go to?

somatic nervous system

this system is in control of motor neurons and skeletal muscles

autonomic nervous system

this system divides into two more systems: sympathetic and parasympathetic. part of PNS.

parasympathetic nervous system

this system conserves energy. “rest and digest” responses

sympathetic divison

mobilizes body systems. “fight or flight” responses

white matter

internal matter

basal nuclei

deep within white matter
