Medulla Oblongata

Contains vital centers that regulate heartbeat, breathing, blood pressure, vomiting, and coughing

Cerebellum

Smoothes and coordinates skilled skeletal muscle movement; also posture and balance or equilibrium

Pineal Gland

Secretes Melatonin, controls the sleep-awake cycle

Hypothalamus

controls and integrates the autonomic nervous system; regulates hormones, emotional behavior, temperature, eating, and drinking behavior

Cerebral Cortex

Interprets sensory input, controls skilled skeletal muscle movements, and is involved in emotional and intellectual processes

Pons

helps control breathing; conducts impulses to and from the cerebellum, midbrain, and medulla

Thalamus

relays all sensory input to the cerebral cortex; involved in skeletal muscle actions and memory processing

Temporal Lobe

coordinates visual and auditory reflexes

basal ganglia

coordinates gross, automatic muscle movements, also involved with limbic system

corpous Callosum

white fiber tracts communicating between hemispheres

hippocampus

one part of the limbic system that is important for memory and learning

tract

in the CNS, a collection of axons

Dura Mater

sac that envelops arachnoid mater; surrounds/supports dural sinuses; carries blood from brain to heart; 2 layers

optic nerve

uses electro chemical data-transfer system; transmits visual info from receptors on retina to brain for interpretation

hypothalamus

thermostat for body; sets desired body temp. and stimulates heat production and retention

white matter

messages pass through different areas of gray matter w/in NS

gray matter

routes sensory stimulus to interneurons in order to create a response, convey messages in special cells

temporal lobe

organize sensory input, hearing, memory, meaning and language, emotion, and learning

pituitary gland

growth, blood pressure, breast milk, sex organs, thyroid, metabolism

pons

arousal; control autonomic functions; sensory roles

cerebellum

processes input from other areas of brain; receives info

medulla oblongata

controls autonomic functions ; connects high levels of brain to spinal cord

spinal cord

info highway of body; messages sent basic and forth between brain and rest of body

olfactory

sense external stimulus and encode it as electric signal (smell)

corpus collosum

communication between hemispheres; eye movement, connect hemispheres . tactile localization maintains balance of atterti and arousal

brain stem as whole

basic vital life functions breathing, heartbeat, blood pressure

forebrain

controls cognitive sensor and motor functions: regulater temp. reproductive organs, eating, sleeping, etc.

hindbrain

support vital bodily processses coordinate motor activities posture sleep patters equilibrium

midbrain

vision, hearing, eyesight, breathing, reflexes, swallowing

Frontal Lobe

Primary Motors; language, comprehension, and speech

Occipital Love

Interpretation; vision

parietal Lobe

Taste; somatic sensory; speech/language

Temporal Lobe

hearing, memory, smell

cerebellum

produces smoothly coordinated skeletal muscle activity
