Key: highlighted and green = chapter header red/bolded/underlined = blanks on notes green = things the professor said in class. Chapter 11: fundamentals of the nervous system and nervous tissue. Central nervous system (cns: brain and spinal cord of dorsal body cavity, integration and control center, interprets sensory input and dictates motor output. 11. 2 neuroglia: nervous tissue histology, nervous tissue consists of two principal cell types, neuroglia (glial cells): small cells that surround and wrap delicate neurons, neurons (nerve cells): excitable cells that transmit electrical signals. 11. 4 membrane potentials: like all cell, neurons have a restoring membrane potential, unlike most other cells, neurons can rapidly change resting membrane potential. Large proteins serve as selective membrane ion channels. Open only with binding of a specific chemical (example: neurotransmitter: voltage-gated channels. Open and close in response to changes in membrane potential: mechanically gated channels. Open and close in response to physical.
