It plays a major role in the body, creating and secreting many bodily hormones. The gland secretes different fluids that are important for the body to function. The body's temperature, physical, and sexual functions are regulated by this gland. One of the major glands are controlled through this cavity. The cerebrum is the most anterior part of the brain, located in the top half of the skull, consisting of two hemispheres separated by a fissure and connected by the corpus callosum. It is responsible for integrating complex sensory and neural functions, and subsequently initiating and coordinating voluntary activity in the body. The cortex is the outer layer of the cerebrum, composed of folded grey matter. Its neuron cell bodies, dendrites, synapses, axons, and axon terminals play a crucial role in consciousness. The two hemispheres are divided into four lobes, distinct sections of the organ: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Our understanding of the specific functions of the cerebral cortex are based on the theories of localisation and lateralisation. 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. The meninges are the three membranes that line the skull and vertebral canal, and enclose the brain and spinal cord. The Cerebrospinal Fluid serves a vital function in the cerebral autoregulation of cerebral blood flow. Cerebrospinal Fluid occupies the subarachnoid space and the ventricular system around and inside the brain and spinal cord. Neurocranium Intracranial pressure Paranasal sinuses Function There are twelve cranial nerves that are responsible for controlling the cranial cavity. These nerves are responsible for providing necessary sensory information for things such as smell, taste, hearing, and sight. The ability to sleep and chew is also a part of one of the things the cranial cavities in charge of. In order for the cranial cavity to be able to do all these functions it has to have the organs to be able to control those systems. The cranial cavity houses the Brain, Meninges, and 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
