PSYCH 100 Lecture Notes - Lecture 8: Peripheral Nervous System, Central Nervous System, Behavioral Neuroscience
Document Summary
Nervous system- a network of cells that carries info to and from all parts of the body. Brain- interprets info, sends info, stores it. Spinal cord- pathway that connects to the peripheral nervous system. A branch of the life sciences that deals with the structure and function of neurons, nerves, and nerves tissue. Biological psychology (behavioral neuroscience)- branch of neuroscience that focuses on biological bases of psychological processes, behavior, and learning. Soma (cell body)- maintains life of the cell, where nucleus is located. Axon- message is carried or passed along the axon. Myelin sheath- fatty layer around axon to insulate the neuron, protect it, and speed up neural transmission. Multiple sclerosis- attacks the myelin sheath and it deteriorates. Synaptic knob- they are the transmitters, transmit into the next neuron. Glial cells separate, support, and insulate the neurons from each other. Clean up waste, neurons may die off, glial cells collect.
