A thermosensory neuron in the skin converts heat energy to nerve impulses via a conversion called _____.A. sensation
pshichka [43]

Answer:

Sensory transduction

Explanation:

Sensory transduction is a process by which the sensory neuron transforms the obtained sensory information into an electric signal. Sensory neurons are the afferent neurons and are activated when they receive stimulus from a sensory receptor. This is followed by the firing of action potential to convey the sensory information into the CNS through the cranial or spinal nerve.

Change in temperature serves as a stimulus for thermosensory neurons present in the skin. The activated thermosensory neuron then produces an electric signal by the process of sensory transduction during which a nerve impulse is generated and action potential to convey the information.

Renin is released by cells of the apparatus in response to afferent arteriole pressure and the degree of stretch of the arteriol
astra-53 [7]

Answer: True

Explanation:

Renin ( angiotensinogenase), is an aspartic protease protein which is secreted by kidney that participates in the body's renin – angiotensin – aldosterone network that mediates arterial vasoconstriction and extracellular fluid volume.

Renin is released by cells of the juxtaglomerular apparatus in response to the stimuli of decrease in arterial blood pressure and the degree of stretch of the arteriole wall.

Hence, the statement is true.
