| Question | Answer |
|---|---|
| central nervous system | brain and spinal cord |
| peripheral 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 emotions and control of autonomic nervous system |
| hippocampus | Involved in memory |
| corpus callosum | Large bundle of axons that connect the two cerebral hemispheres |
| limbic system | Association area including amygdala and hippocampus, plays important part in memory and emotion |
| pituitary gland | Not part of brain. Endocrine gland controlling other glands. |
| frontal lobe | Controls voluntary movements intelligence and personality; behind forehead. |
| parietal lobe | Top and toward rear of head Involves sensation and perception, concerned with integrating sensory input |
| temporal lobe | Just above ears; involved in hearing, language processing and memory. |
| occipital lobe | Back of head; responds to visual stimuli |
| medulla oblongata | Controls breathing and heart rate. |
| Broca's area | Left hemisphere area which controls production of language. |
| Wernicke's area | Left hemisphere area which controls understanding of language. |
| sensory areas | Receive inputs directly from receptors. |
| association areas | Compare input with previous experience to interpret them and judge response |
| motor areas | Send impulses to muscles and glands |
| Cerebrum | Controls higher brain functions; conscious thought, emotionl response, ability to override some reflexes, intelligence, reasoning, judgement. |
