Taste receptor is an example of:
Correct answer: D. Chemoreceptors
- A. Mechanoreceptors
- B. Nociceptors
- C. Photoreceptors
- D. Chemoreceptors
Explanation
Chemoreceptors are specialized sensory receptors that detect changes in the chemical composition of the environment. They respond to specific chemical stimuli, such as the levels of oxygen (O₂), carbon dioxide (CO₂), and pH in the blood or other body fluids. Chemoreceptors play a critical role in regulating respiratory and cardiovascular functions by signaling the nervous system to adjust breathing rate, heart rate, and blood pressure based on changes in blood gas levels. They are primarily located in the carotid bodies, aortic bodies, and the medulla of the brainstem.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
