The crown is the top portion of the head behind the vertex. The anatomy of the crown varies between different organisms. The human crown is made of three layers of the scalp above the skull. The crown also covers a range of bone sutures, and contains blood vessels and branches of the trigeminal nerve.
The structure of the human crown provides a protective cavity for the brain and optimizes the crown's ability to ensure the is safe. Different parts of the neocortex, such as the frontal lobe and the parietal lobe, are protected by the meninges and bone structures. Other organisms, such as whales, have their blowholes on their crown, causing a flattened head shape. Some bird species have a crest located on their crown, used for communication and courtship.
Macroevolution of the human crown has led to different structures between modern and archaic human species, such as significant changes to the cranial vault. The human crown is prone to different injuries and disorders with various causes, medical signs and symptoms, methods of diagnosis, and treatments. For example, illnesses such as cerebrospinal fluid leak, which results in intense headaches that are localised underneath the crown. Other diseases include meningioma, a tumor surrounding essential blood vessels and nerves that may be near the crown, causing symptoms such as memory loss.
Structure[edit]
The crown is at the top of the human skull, and contains the different layers of the scalp. The scalp has three distinct layers including the cutaneous layer, a subcutaneous connective tissue layer, and a muscular layer. The crown covers bone layers of the skull. It is between 4 and 7 millimetres (0.16 and 0.28 in) thick, and varies between different people. It tends to increase in thickness with age.

What is the top of the back of the head called?
The crown is the highest point on your scalp, toward the back of your head. It's also called the vertex.
What do you call the back part of the head?
The occipital bone is a bone that covers the back of your head; an area called the occiput. The occipital bone is the only bone in your head that connects with your cervical spine (neck). The occipital bone surrounds a large opening known as the foramen magnum.
What is the area of the back of the head?
The occipital lobes sit at the back of the head and are responsible for visual perception, including colour, form and motion. Damage to the occipital lobe can include: Difficulty with locating objects in environment.
What is the notch on the back of the skull?
An occipital bun, also called an occipital spur, occipital knob, chignon hook or inion hook, is a prominent bulge or projection of the occipital bone at the back of the skull.
