Question | Answer |
---|---|
central nervous | brain and spinal cord |
peripherial nervous system | somatic and autonomic system |
hypothalumus | Contains receptors that monitor blood temp and water potential. Involved in controlling autonimic nervous system and pituitary gland. |
thalamus | relays info to cerebral cortex |
cerebellum | rounded structure involved in motor cordination and posture |
cerebral cortex | extensive, wrinkled outer layer of the forebrain; governs higher brain functions, such as thinking, learning, and consciousness |
amygdala | Part of limbic system, involved in fear and the discrimination of objects necessary for organisms survival |
hippocampus | involved in memory |
pons | governs sleep and arousal |
corpus callosum | the large bundle of axons that connect the brains two hemispheres |
limbic system | Association area that includes the amygala and hippocampus- that play important roles in memory and emotion |
pituitary gland | an important endocrine gland at the base of the skull that controls growth and regulates other glands |
frontal lobe | controls voluntary muscles intellegence and personality; behind forehead |
parietal | top and toward the rear of head; registering spatial location, attention and motor control |
temporal | just above ears; involved in hearing, language processing and memory |
occipital | back of head; responds to visual stimuli |
medulla oblongata | Controls breathing and heart rate, action of smooth muscle in gut. |
Broca's area | Left hemisphere area which controls production of language |
Wernicke's area | Left hemisphere area responsible for understanding language |
sensory areas | Receive impulses directlt from receptors |
association areas | Compare input with previous experience to interpretthem and judge response |
motor areas | Send impulses to muscles and glands |
cerebrum | Controls higher brain functions; conscious thought and emotional response, ability to override some reflexes, intelligence, reasoning, judgement. |
