Document Summary

Lowering the membrane potential of the cell below its equilibrium value. Potential difference across the membrane in a resting neuron. It protects axons and speeds the rate of nerve impulse transmission. Makes proteins and lipids, either to stay in the cell or for transport out of the cell. Protects the cell and creates a semi-permeable barrier out of the cell. Support cell that nourishes neurons, removes their wastes, defends against infections. These cells are very simple cells which form covering of other cells. These cells are very long and have many branching at either ends. Answer: the reflex arc only depends on the integrity of the fibers at a single spinal level. In the reflex arc, the motor response to the stimulus is automatic and involuntary and does not depend upon the passage of information to the brain.
