The human crown is prone to different injuries and disorders with various causes, medical signs and symptoms, methods of diagnosis, and treatments.

Other diseases include meningioma, a tumor surrounding essential blood vessels and nerves that may be near the crown, causing symptoms such as memory loss.

Different sutures between the frontal and parietal bones of the skull expand in specific directions, causing a symmetrically shaped human head.

[6] In bird anatomy, the crown is the top of the head, or more specifically the zone from the frons, or forehead, extending posteriorly to the occiput and laterally on both sides to the temples.

[10] For instance, the meninges which include flexible sheets between the brain, spinal cord, and skull aim to protect the frontal lobe, located behind the forehead.

The parietal lobe of the neocortex which contains a strip targeting the sense of touch and allows for the representation of space for action is protected due to the thick layers of the crown.

The extent of the injuries and diseases directed to the human crown causes additional implications to the brain, impacting the individual's ability to function normally.

The cerebrospinal fluid leak is mainly caused by a head, brain, or spinal injury which tears the meninges membrane.

For example, consuming fluids such as water aims to stop excess leakage and reduce headaches, and antibiotics are also provided if signs of infection are clear such as fever and chills.

Another symptom such as bleeding results in the build-up of pressure in the skull since it is an enclosed cavity and thus pushes the brain to the brainstem opening leading to a coma.

For example, the computerised tomography scan identifies the site of the fracture and any associated injuries to the brain, whereas magnetic resonance imaging highlights the damaged tissue.

The chronic disorder involves the progressive loss of bone, although, symptoms such as intense pain are not evident during the initial stages.

The symptoms of the disease are clear after a fracture to the crown of the skull causing patients to experience abnormal deformities as well as issues to the nervous system.

[23] Diagnosis occurs through physical exams such as X-rays and magnetic resonance imaging which find the decrease in bone mass (osteolysis) and deformities.

[24] The macroevolution of the human species resulted in changes such as the increase in bone and muscle structures that support the crown of the head, compared to primates.

[25] The sagittal vault's morphology, which is the area that joins the two parietal bones together to make up the structure of the crown, has remained the same for archaic and modern human species.
