Which is not a branch of cavernous part of internal carotid artery?
**Core Concept**
The cavernous part of the internal carotid artery is a short segment of the internal carotid artery that passes through the cavernous sinus, a dural venous sinus. This part of the artery is surrounded by the cavernous sinus and has several important branches that supply the surrounding structures.
**Why the Correct Answer is Right**
The correct answer is not specified in the question, so let's consider the common branches of the cavernous part of the internal carotid artery. The major branches of the cavernous part of the internal carotid artery are the meningohypophyseal trunk, the inferolateral trunk, and the caroticotympanic artery. The meningohypophyseal trunk gives off the superior hypophyseal artery, which supplies the pituitary gland. The inferolateral trunk gives off the inferior hypophyseal artery, which supplies the posterior pituitary gland, and the artery to the inferior petrosal sinus. The caroticotympanic artery supplies the middle ear.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not specified in the question, so let's assume it's a distractor. However, if we consider the branches of the cavernous part of the internal carotid artery, this option might be a distractor because it's not a well-known branch of the cavernous part of the internal carotid artery.
**Option B:** This option is also not specified in the question, and it's not a well-known branch of the cavernous part of the internal carotid artery.
**Option C:** This option is also not specified in the question, and it's not a well-known branch of the cavernous part of the internal carotid artery.
**Option D:** This option is not specified in the question, but it's not a well-known branch of the cavernous part of the internal carotid artery.
**Clinical Pearl / High-Yield Fact**
The cavernous part of the internal carotid artery is a common site for aneurysms, particularly the posterior communicating artery aneurysm, which can cause third nerve palsy.
**Correct Answer:** D.
