A sensory receptor is specialized for the
A) detection of physical events.
B) coordination of movement of the hands and fingers.
C) detection of specific chemicals released from other neurons.
D) detection of neurohormones in the blood.
E) detection of electrical changes in nearby neurons.

Question

Quizplus · Accepted Answer

A sensory receptor is a type of specialized cell or neuron that is dedicated to detecting and responding to specific types of physical events, such as light, sound, heat, pressure, or chemicals in the environment. These receptors are essential for our ability to perceive and respond to sensory stimuli from our surroundings. Choice B is incorrect because coordination of hand and finger movement involves the motor system, not sensory receptors. Choice C is incorrect because detection of specific chemicals released from other neurons would be the job of specialized receptors called neurotransmitter receptors, not sensory receptors. Choice D is incorrect because neurohormones are not typically detected by sensory receptors; they are typically detected by specialized cells in the endocrine system. Choice E is incorrect because while some neurons are capable of detecting and responding to electrical changes in nearby neurons, this is not the primary function of sensory receptors.
