PLAY
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
