There are four types of sensory receptors that respond to one of the four primary stimuli.
Thermoreceptors detect temperature changes in the environment.
Mechanoreceptors detect changes in pressure
Photoreceptors detect the photons composing light
Chemoreceptors detect chemical stimuli and are found inside the body (for example blood vessels). They are also responsible for our sense of taste and smell.
Thus, the correct answer to the question is D. on the tongue and in the nose, to detect taste or odor.
Answer:
The correct answer will be option-B.
Explanation:
The patellar tendon reflex is the kicking movement of the lower leg in response to the tap on patellar cap used to test the L2, L3, and L4 segments of the spinal cord in the body.
The spinal cord interacts with muscles through muscle sensors called muscle spindle which signals after the stretching of the muscle. The signals are sent to the spinal cord through afferent neurons or sensory neurons which starts the reflex action to prevent overstretching of the muscle.
Thus, Option-B is the correct answer.
