orbital wall

The ethmoid bone represents a fascinating cornerstone of human skull anatomy, serving as a critical junction between the facial skeleton and cranial cavity. This complex bone not only houses essential sensory structures but also provides crucial support for the eyes, nose, and brain, making it an indispensable component of human cranial architecture. Understanding its intricate anatomy is vital for medical professionals dealing with sinonasal disorders and orbital pathologies.

The lacrimal bone, the smallest and most fragile of the facial bones, plays a crucial role in the formation of the orbit and lacrimal drainage system. This thin, scale-like bone contributes to the medial orbital wall and helps form the nasolacrimal duct, making it essential for proper tear drainage and orbital integrity. Understanding its anatomy is crucial for ophthalmologists, orbital surgeons, and medical professionals dealing with orbital pathologies.
