The nervous system consists of the brain and spinal cord, which are responsible for relaying sensory and motor signals throughout the body.

Meninges primarily serve to cover and protect the brain, rather than regulating body temperature, storing memories, or producing cerebrospinal fluid.

The cerebrum is the largest part of the brain and is responsible for higher brain functions such as thought and action. It has a folded surface with raised gyri, deep fissures, and shallow sulci.

The saggital fissure is a long, deep groove that divides the two cerebral hemispheres.

The corpus callosum is a structure in the brain responsible for connecting the two hemispheres to facilitate communication between them.

The cerebellum is the second largest part of the brain and is responsible for coordinating muscle movements, balance, posture, and fine motor control.

The brain stem serves as a bridge connecting the higher brain regions (cerebrum and cerebellum) to the spinal cord for vital functions such as breathing, heart rate, and consciousness.

The medulla oblongata is a vital part of the brain stem and is continuous with the spinal cord, situated at the most posterior end. It plays a crucial role in controlling functions such as breathing, heart rate, and blood pressure.

The olfactory bulb is specifically responsible for the sense of smell and is located above the nasal cavity. Olfactory nerves connect to the olfactory bulb to process smell signals.
