Document Summary

Studies the connection between the brain, the mind, and behaviour. Only relatively recently the brain was considered important for thought, feeling, personality. Chapter 3: learning objectives the nervous system. Peripheral nervous system: somatic nervous system, autonomic nervous system. Central nervous system: spinal cord, brain. Glial cells outnumber neurons 10:1, and support neurons by: Interneurons connect neurons together: protecting brain from toxins, forming blood-brain barrier, getting rid of neuron waste, creating myelin. Afferent neurons (sensory) relay information from the senses to the brain and spinal cord. Efferent neurons (motor) send information from the central nervous system to the glands and muscles, enabling the body to move. Interneurons carry information between neurons in the central nervous system. Axon transmits information to as many as 50,000 other neurons. Axon terminals are at the end of axons and form synapses with other neurons. Dendrites are branches that extend from the cell body and receive most of the information from other neurons.
