Which of the following does NOT have dual nerve supply
**Core Concept**
The question is testing the student's knowledge of the dual innervation of various organs in the human body. Dual innervation refers to the simultaneous supply of nerve fibers to an organ from two separate nerves, often providing both sympathetic and parasympathetic control.
**Why the Correct Answer is Right**
The correct answer is the organ that does not receive dual innervation. This can be due to various reasons such as the organ being primarily controlled by a single type of nervous system (sympathetic or parasympathetic), or it being innervated by a single nerve that carries both sympathetic and parasympathetic fibers.
**Why Each Wrong Option is Incorrect**
* **Option A:** This organ has dual innervation and is controlled by both sympathetic and parasympathetic nerves.
* **Option B:** This organ is primarily innervated by a single type of nervous system, but it can receive some dual innervation under certain conditions.
* **Option C:** This organ has dual innervation and is controlled by both sympathetic and parasympathetic nerves.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that dual innervation is not a universal characteristic of all organs, and some organs may receive single or variable innervation. Understanding the specific innervation patterns of various organs is crucial for diagnosing and managing various medical conditions.
**Correct Answer:** C.
