Which one of the following is a branch of the facial nerve
**Core Concept**
The facial nerve, also known as the seventh cranial nerve (CN VII), is a complex nerve that controls facial expressions, taste, and hearing. It has multiple branches that supply the muscles of facial expression, as well as other structures in the face and head.
**Why the Correct Answer is Right**
The correct answer is a branch of the facial nerve that innervates the muscles of facial expression. The facial nerve has five main branches: the temporal, zygomatic, buccal, marginal mandibular, and cervical branches. Each branch innervates a specific group of muscles that are responsible for different aspects of facial expression.

* **Option A:** This option is incorrect because it is not a recognized branch of the facial nerve.
* **Option B:** This option is incorrect because it is actually a branch of the trigeminal nerve (CN V), not the facial nerve.
* **Option D:** This option is incorrect because it is actually a branch of the trigeminal nerve (CN V), not the facial nerve.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the facial nerve has multiple branches that can be affected by various conditions, such as Bell's palsy, which is a common cause of facial weakness.
**Correct Answer: C. Temporal Branch. Temporal branch of the facial nerve.**
