Proprioceptors

Question

Proprioceptors
A)do not adapt to constant stimulation.
B)for the most part produce information that is processed consciously.
C)do not send information continuously to the CNS.
D)are free nerve endings that branch within the walls of a distensible organ.
E)are exemplified by receptors in the carotid and aortic sinus.

Accepted Answer

Proprioceptors, which are specialized sensory receptors found in muscles, tendons, and joints, provide the central nervous system (CNS) with information about body position and movement. They do not adapt to constant stimulation, meaning they continue to send signals to the brain about the position of the limbs and body in space, even when the position is held constant. This is crucial for maintaining posture and balance. The other options are incorrect because proprioceptors primarily provide unconscious information about body position (B), they do send information continuously to the CNS to monitor body position (C), they are not free nerve endings in the walls of distensible organs (D), and they are not exemplified by receptors in the carotid and aortic sinus, which are involved in monitoring blood pressure (E).
