Which of the following biological components function as effectors______________?
Show answer Hide answer
Answer: D. Both ‘a’ & ‘b’
Explanation
Effectors are specialized organs, such as muscles and glands, that respond directly to neural stimuli. Muscles act as effectors by contracting to produce physical movement throughout the living body. Glands serve as effectors by secreting hormones or enzymes in response to nervous system signals. Neural reflex arcs connect sensory input receptors directly to integrating centers and peripheral effectors. Endocrine and exocrine glands release chemical products to regulate numerous internal physiological functions. Motor neurons stimulate muscle fibers at neuromuscular junctions to trigger coordinated physical contractions.
Coordination between sensory inputs and muscular effectors is vital for escaping sudden environmental dangers. Medical treatments for neurological conditions often focus on restoring proper communication with peripheral effectors. Homeostatic feedback loops rely on glandular effectors to adjust hormone levels in the bloodstream. Muscles are correct effectors, but ignoring glandular contributions makes this answer incomplete on its own. Glands are correct effectors, but ignoring muscular tissue leaves out half of the correct physiological scope. Sensory organs function as receptors that detect environmental stimuli rather than acting as peripheral effectors.
