a. Signal to effector cells in glands or muscles b. Detect and transmit information about the conditions inside and outside the body to the CNS. c. Neurons that conduct electrical signals from one neuron to another d. Integrates sensory information and sends signals to effector cells e. Long projections of neurons that conduct electrical signals to other neurons. f. Dendrites

QUESTION 4

1. Which of the following statements is true?

	a.	Electric potential refers to a difference in charges across a plasma membrane while action potential refers to a temporary change in membrane potential.
	b.	Action potential refers to the electric potential across a membrane while the depolarization refers to a temporary change in membrane potential.
	c.	Threshold potential is a difference in charges across membranes of sensory neurons while action potential is a difference in charges across motor neurons.
	d.	Membrane potential refers to the electric potential across a membrane while the action potential refers to a temporary change in membrane potential.
