The Class of Sensory Receptors That are Structurally the Simplest

Question

The class of sensory receptors that are structurally the simplest are
A)separate cells
B)encapsulated nerve endings
C)proprioceptors
D)free nerve endings
E)none of the choices are correct

Accepted Answer

Free nerve endings are the most structurally simple sensory receptors, as they consist of just the terminal endings of sensory neurons without any additional supportive structures. Separate cells (A) and encapsulated nerve endings (B) both contain multiple cells and structures, while proprioceptors (C) are a specific type of sensory receptor that detect changes in body position and movement.
