ANT 318L Chapter Notes - Chapter 11: Inhibitory Postsynaptic Potential, Electrochemical Gradient, Active Transport
Document Summary
Monitors for changes and sends information back to the spinal cord and brain. Integration information collected from sensory receptors is processed and decisions on how to act are made: motor output the decision is sent to effector organs that carry it out in a response, not necessarily physical movement. Cells of the nervous system: neural tissue is made of only two types of cells, neuroglia (cid:894)(cid:862)(cid:374)er(cid:448)e glue(cid:863)(cid:895, neurons, neurons are responsible for conduction messages, neuroglia perform support functions, four types of neuroglia in cns, two in pns. Neuroglia of the pns: satellite cells are found throughout the pns, perform many of the same functions as astrocytes (capillary connections, etc, schwann cells perform similar functions as oligodendrocytes (provide a myelin sheath around. In addition to depolarization, membranes can be hyperpolarized (charges are more segregated, inside of cell becomes more negative: charges in membrane potential can be used as signals, short distance (graded potential) and long distance (action potential)
