- defend nervous tissue- support nervous tissue & bind it to various other structures - help repair cells - remove pathogens & impurities - regulate liquid composition in neural tissue
1. A stimulus initiates an action potential.2. The activity potential opens sodium networks in nearby portions that the membrane.3. Open up sodium networks let sodium go into the cell.4. Salt entry into the cell causes another action potential in the adjacent section of the membrane.

1. The nerve advertise arrives in ~ the end of the presynaptic neuron.2. Motor containing neurotransmitter fuse v the axonal plasma membrane.3. Neurotransmitter molecules space released into the synaptic cleft.4. Neurotransmitter molecules tie to receptor in the postsynaptic membrane.5. The activity of the postsynaptic cabinet is altered.
reflexes entailing smooth muscle or glands are autonomic reflexes. An example of the former type is the ____________, a large reflex that involves striking a tenon, in the patellar region.
Sue suffered from _______, a an illness associated w/ demyelination. The _______ coating that neuronal axons was destroyed by one autoimmune reaction. Lesions were obvious in the type of spinal cord tissue containing myelinated axons, well-known as _______. Sue"s feeling of touch to be impaired because of damages to neurons in the ________ tracts of her spinal cord. This neurons are recognized as ________, or afferent, neurons, & they obtain input indigenous neurons entering the spinal cord v the _______ root. Sue"s muscle control was impaired because of the damages to __________ neurons in the _________ tracts of she spinal cord. Motor impulses indigenous this pathway leave the spinal cord through the _________ root.

Sue suffered from lot of SCLEROSIS, a condition associated w/ demyelination. The MYELIN coating of neuronal axons was ruined by an autoimmune reaction. Lesions were apparent in the form of spinal cord tissue containing myelinated axons, well-known as WHITE MATTER. Sue"s feeling of touch was impaired due to the fact that of damages to neurons in the ASCENDING tracts of her spinal cord. These neurons are known as SENSORY, or afferent, neurons, & they obtain input from neurons entering the spinal cord with the DORSAL root. Sue"s muscle regulate was impaired due to the fact that of the damage to engine (OR EFFERENT) neurons in the diminish tracts of she spinal cord. Engine impulses native this pathway leaving the spinal cord with the VENTRAL root.
the part of the spinal cord made up of cell bodies & unmyelinated axons is referred to as the ___________
