In this topic page, we’ll learn about various anatomical aspects of the head and neck, such as the skull, eyes, teeth, nose, ears, and neck. On the other end, the head is durable enough to protect the fragile brain but intricately designed to facilitate the passage of the complex neurovascular network. The neck is resilient enough to sustain a five kilogram weight 24/7, yet sufficiently mobile to move it in several directions. The head and neck are two examples of the perfect anatomical marriage between form and function, mixed with a dash of complexity. ![]()
