Document Summary

Central nervous system(brain and spine: neurons are the building blocks, neurotransmitters are the messengers, they carry signals between nerve cells or neurons. Brain: evolutionary perspective: reptilian brain, hindbrain and midbrain, reflexive responses and arousal, old mammalian brain, hypothalamus/ limbic system, emotion and learning, new mammalian brain, cerebrum, capacity for complex thought. Hypothalamus: regulation of basic biological drives related to survival, control of hunger, thirst, sex, body temperature. Figure 3. 6 organization of the human nervous system. Broca"s area: aphasia: lose the ability to speak, commonly affects people who"ve had a stroke or other injury to the part of the brain that controls language. Wernicke"s area important part of the brain that is involved with helping us to understand spoken language. 2. the peripheral nervous system: somatic nervous system (voluntary, muscle control. Efferent (outgoing) nervous: automatic nervous system (involuntary, connects to internal organs. 3 basic components of most neurons: cell body, axon, dendrites.
