The basic function of the nervous system is= integration (coordination), communication (transmission) The PET scan from a person doing a particular mental process= shows what parts of the brain are most active during that mental process Glands are part of the endocrine system, this system is slower and less specific in its site of action The four main parts of the neuron are= dendrite, cell body, axon, and axon terminal (button) Dendrite = receive info from other neurons Soma = the cell body of a neuron Axon = The long taillike part of a neuron that is the cell’s transmitter Terminal buttons = end of the axon that contains chemicas important to neutral transmission. Somatic system = nerves that transmit info toward the brain and connects to skeletal muscles for movement, part of the PNS (peripheral nervous system) Autonomic system = nerves that control the automatic needs of the body (heart rate, digestion, etc) part of the PNS. Cerebellum = A hindbrain structure at the base of brain that is involved in the coordination of complex motor skills. Cerebral Cortex = higher mental processes. Thalmus = Gathering point for input from the senses. Hypothalamus = Regulation of various motivational activites, including eating, drinking, and sexual behavior. Frontal lobe = hempishphere of the cerbral cortex, contails the motor cortex and may be involved in higher level though processes. Parietal lobe = Sense of touch…Tempotal lobe= speech and language…occipital lobe= visual processing. Hippocampus = memories, memory specific events.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
