Question

multiple choice question
which term refers to an organ that receives both sympathetic and parasympathetic input?
o dual innervated
somatosensory
o postganglionic
o nicotinic

Explanation:

• Dual innervated: Organs that receive both sympathetic and parasympathetic input are called dual innervated. The sympathetic and parasympathetic nervous systems often have opposing effects on these organs, allowing for fine - tuned regulation.
• Somatosensory: Refers to the sensory system that deals with the perception of touch, pressure, pain, temperature, and proprioception (body position) from the body's surface and internal organs. It has no relation to the autonomic nervous system (sympathetic and parasympathetic) innervation of organs.
• Postganglionic: Describes the neurons in the autonomic nervous system that are after the ganglion. Sympathetic and parasympathetic both have postganglionic neurons, but this term does not specifically refer to an organ receiving both types of innervation.
• Nicotinic: Refers to a type of acetylcholine receptor. Nicotinic receptors are found on postganglionic neurons in both the sympathetic and parasympathetic nervous systems (as well as at the neuromuscular junction in the somatic nervous system), but this term is about a receptor type, not organ innervation.

Answer:

dual innervated
