What is the term for the dense, fibrous tissue connecting the occipital and frontalis muscles?

The term for the dense, fibrous tissue that connects the occipital muscle at the back of the head with the frontalis muscle at the forehead is known as the epicranial aponeurosis. This structure serves as an important connective sheet that allows for the movement of the scalp muscles. It helps in facilitating the actions that involve raising the eyebrows and moving the scalp, providing a functional link between the muscle groups.

Other terms in the options refer to different types of connective tissues. Fascia is a more general term for connective tissue that surrounds muscles and other structures. Ligaments connect bones to other bones at joints, while tendons connect muscles to bones. In contrast, the epicranial aponeurosis serves a unique purpose in connecting specific muscles of the scalp, making it the correct term in this context.
