Number the cranial nerves 

## Cranial Nerves Coloring

The diagram depicts the underside of the human brain, highlighting the cranial nerves and associated structures. Key elements in the diagram include:

- **Cerebrum**: The largest part of the brain, shown at the top of the diagram with a label extending outward.
- **Longitudinal Fissure**: A deep groove marking the division between the two hemispheres of the cerebrum.
- **Olfactory Bulb**: Located at the front, responsible for the sense of smell.
- **Optic Nerve**: Transmits visual information from the retina to the brain.
- **Optic Chiasma**: The area where optic nerves cross.
- **Infundibulum**: Part of the pituitary gland structure.
- **Oculomotor Nerve**: Involved in eye movement.
- **Midbrain**: A small central part of the brainstem high on the diagram.
- **Trochlear Nerve**: Also involved in eye movement.
- **Pons**: Bridge between various parts of the nervous system, including the cerebellum and medulla.
- **Abducens Nerve**: Another nerve related to eye movement.
- **Medulla Oblongata**: The lower half of the brainstem, controlling autonomic functions such as breathing and heart rate.
- **Trigeminal, Facial, and Auditory Nerves**: Below the cerebrum, with functions related to sensation, facial muscles, and hearing, respectively.
- **Glossopharyngeal, Vagus, Accessory, and Hypoglossal Nerves**: Involved in various functions including taste, swallowing, speech, and innervation of several muscles.
- **Cerebellum**: Located at the rear of the brain, beneath the cerebrum, responsible for coordination and balance.
- **Spinal Cord**: Extends down from the medulla oblongata, transmitting neural signals between the brain and the rest of the body.

Expert Solution
Step 1: Introduce about the cranial nerves

The nerves that originate directly from the brain are known as cranial nerves. The human body contains 12 pairs of cranial nerves. These nerves are of three types, that are- sensory or afferent, motor or efferent and mixed types.
