The trigeminal nerve has three main branches: ophthalmic (V1), maxillary (V2), and mandibular (V3).

A branch of the mandibular nerve (V3) that innervates the lower teeth.

Branches of the maxillary nerve (V2) that innervate the upper teeth.

The lingual nerve, a branch of the mandibular nerve, innervates the lingual gingiva (gum), buccal gingiva, and tooth pulp.

Each tooth's pulp, buccal gingiva, and lingual gingiva, pulp are innervated by different branches of the trigeminal nerve.

The supply of nerves to a body part, enabling it to communicate with the brain.

A cluster of neuron cell bodies located outside the central nervous system.

A nerve that carries sensory information from the body to the brain or spinal cord.

A nerve that carries motor commands from the brain or spinal cord to the body.

The control center of the nervous system, composed of the brain and spinal cord.

The largest part of the brain, responsible for higher-level functions like thinking, learning, and memory.

The second largest part of the brain, responsible for balance, coordination, and movement.

The part of the brain that connects the cerebrum and cerebellum to the spinal cord, controlling vital functions.

The nervous system controls all body functions. It activates, coordinates, and regulates everything we do.

The PNS connects the CNS to the rest of the body. It carries signals to and from the brain and spinal cord.

The autonomic nervous system controls unconscious functions like breathing, heart rate, and digestion.

The basic unit of the nervous system. It transmits information as electrical signals.

The junction between two neurons or between a neuron and an organ, where signals are transmitted.

A bundle of neural processes outside the CNS. It's how the PNS carries information.

The fifth cranial nerve, responsible for sensation in the face and motor control of chewing.

The part of the PNS that carries sensory information from the body to the CNS.

The part of the PNS that carries commands from the CNS to muscles and glands.

The part of the PNS that controls involuntary body functions like heart rate, breathing, and digestion.

The part of the ANS that prepares the body for 'fight-or-flight' responses, like increasing heart rate and diverting blood to muscles.

The part of the ANS that promotes 'rest-and-digest' responses, like slowing heart rate and stimulating digestion.

12 pairs of nerves that connect directly to the brain, responsible for sensory and motor functions of the head and neck.

There are 12 pairs of cranial nerves.
