Neurons are electrically excitable cells that transmit signals throughout the body. Neurons employ both electrical and chemical components in the transmission of information. Neurons are connected to other neurons at synapses and connected to effector

The sensory system is the portion of the nervous system responsible for processing input from the environment. Beginning with detection through the transfer of stimuli to the central nervous system, the peripheral nerves and their associated receptors

Neurons are electrically excitable, reacting to input via the production of electrical impulses, propagated as action potentials throughout the cell and its axon. These action potentials are generated and propagated by changes to the cationic gradient

The spinal cord is a tubular structure composed of nervous tissue that extends from the brainstem and continues distally before tapering at the lower thoracic/upper lumbar region as the conus medullaris. The spinal cord is anchored distally by the filum

As the largest of the cranial nerves, the trigeminal nerve is responsible for the primary sensory input from the head and neck as well as providing motor innervation to the muscles of mastication. The trigeminal nerve innervates key vascular structures
