What is the name of the tissue that covers the top of the head?

The tissue that covers the top of the head is known as the epicranial aponeurosis. This structure acts as a fibrous connective tissue that forms a connection between the frontalis muscle at the forehead and the occipitalis muscle at the back of the head. It is an important component of the scalp, providing strength and support to the overlying skin and facilitating movement of the scalp muscles. Understanding the role of the epicranial aponeurosis helps clarify its importance in both anatomy and the functionality of the facial expressions as well as the overall structure of the scalp.

The other options refer to different tissue types: corium is a term that may refer to the dermis or the layer beneath the epidermis in certain contexts, the subcutis (or hypodermis) is the layer of fatty tissue beneath the skin, and dermis, which lies beneath the epidermis, gives skin its strength and elasticity. Each of these tissues plays vital roles, but they do not specifically cover the top of the head like the epicranial aponeurosis does.
