Ethmoid bone forms aiculation with which of the following-
**Core Concept**
The ethmoid bone is a spongy bone in the skull that forms part of the nasal cavity and sinuses. It is characterized by a complex network of thin-walled cells and air cells that contribute to the paranasal sinuses.
**Why the Correct Answer is Right**
The ethmoid bone articulates with the maxilla bone, lacrimal bone, palatine bone, and sphenoid bone. Specifically, the ethmoid bone forms a sutured joint with the maxilla bone, allowing for flexibility and movement during facial expressions. This articulation helps to distribute the forces of mastication and respiration.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not provided, so we cannot evaluate its correctness.
* **Option B:** There is no known articulation between the ethmoid bone and the frontal bone that is relevant to this question.
* **Option C:** The ethmoid bone does not articulate with the occipital bone.
* **Option D:** The ethmoid bone does not articulate with the temporal bone.
**Clinical Pearl / High-Yield Fact**
The ethmoid bone is a key landmark in endoscopic sinus surgery, and its anatomy is crucial for understanding the drainage pathways of the paranasal sinuses.
**Correct Answer:** C.
