The frontal and sphenoid bones are towards the front middle of the skull and in front of the temporal bone. The ethmoid bone is the bone at the roof of the nose that separates the nasal cavity from the brain. It is a part of the dorsal cavity the cranial cavity and the spinal cord. The occipital bone is at the back of the skull. The dorsal cavity is lined by the three meninges. The three meninges are the three membranes that envelop the brain and spinal cord, in which the central nervous system developed, which are the

Cerebrospinal Fluid. The primary function of the brain is supplying information to the rest of the body and to help it function as whole. It helps supply some of the cranial nerves from the face to the feet and also to help get the body performing critical bodily functions.

Localisation is the theory that specific areas of the brain are associated with/responsible for particular physical and psychological functions. Lateralisation is the theory that one hemisphere is dominant over the other/responsible for particular physical and psychological functions.

These nerves are responsible for providing necessary sensory information for things such as smell, taste, hearing, and sight.

In the event that the brain strikes the inside of the skull, there is a risk of a minor traumatic brain injury (concussion). This type of injury can alter brain function, cause memory loss, headaches and/or nausea. A minor traumatic brain injury can be followed by post concussion syndrome. As there

The cranial cavity has a variety of spinal and cranial nerves residing in it. The cranial nerves are responsible for storing sensory information needed for taste, smell, sight and the ability to hear. The spinal nerves allow for the sensory and motor signals to be received, which provide a normal

The cranial cavity includes eight cranial bones and they are collectively combined to form this area. A gland that is found in this cavity is called the pituitary gland which secretes different fluids that are necessary for different parts of the body to function. There are many things that are
