What is the thick connective tissue attached to the skull that spreads down toward the forehead and connects to the frontalis?

1. Aponeurosis

2. Tendon

3. Ligament

4. Fascia

The correct answer is: Aponeurosis

The thick connective tissue attached to the skull that spreads down toward the forehead and connects to the frontalis is referred to as the aponeurosis. Specifically, this structure is known as the galea aponeurotica, which is a strong fibrous layer of tissue that acts as an interconnection between the frontalis muscle and the occipitalis muscle in the scalp. Its primary function is to provide stability and support for the muscles of facial expression, facilitating movement and contributing to the overall appearance and functioning of the forehead area. Unlike tendons, which connect muscles to bones, or ligaments, which connect bones to other bones, the aponeurosis serves a unique role in muscle dynamics across broader areas, providing a flattened, sheet-like tissue that distributes the forces exerted by the muscles. It differs from fascia, which is a more general term for connective tissue surrounding various structures in the body but does not hold the same specific attachment and functional role as the aponeurosis in the scalp.
