Question

Judith is receiving messages in her brain from baroreceptors in her stomach, from chemoreceptors detecting PO2 levels in her blood, and from tactile receptors in her skin. All this information must be transmitted in what format in order to be detected by the central nervous system (CNS)?

a. perceptionb. sensationsc. action potentialsd. pain

Answer 1

Action potentials.

Step-by-step explanation:

Receptors are present in the body surface that helps in the detection of the changing inside and outside environment of the body. Different receptors are sensory receptors, baroreceptors and chemoreceptors.

Action potential is the transmission of nerve impulse that occur due to the change in the electric potential of the cell. The information from the baroreceptors occurs by the propagation of the action potential.

Thus, the correct answer is option (c).
