Action Potential | Rapid depolarization of the cell membrane that results in propagation of the nerve impulse along the membrane. |
Afferent Nerve | Sensory nerve that carries information from the periphery of the body TO the BRAIN or spinal cord |
Anesthesia | Loss of feeling or sensation resulting from the nerve use of certain drugs or gases that serve as inhibitory neurotransmitters. |
Crossover-Innervation | Overlap of terminal nerve fibers from the contralateral side of the dental arch. |
Efferent Nerve | Motor nerve that carries information away from the brain or spinal cord to the periphery of the body. |
Facial Paralysis | Loss of action of the facial muscles. |
Ganglion | Accumulation of neuron cell bodies outside the central nervous system. |
Innervation | Supply of nerves to tissue, structures, or organs. |
Neuron | Cellular component of the nervous system that is individually composed of a cell body and neural processes. |
Neurotransmitter | Chemical agent from the neuron that is discharged with the arrival of the action potential, diffuses across the synapse, and binds to receptors on another cells membrane. |
Nerve | Bundle of neural processes outside the central onerous system; a part of the peripheral nervous system. |
Nervous System | Extensive network of structures that activates, coordinates, and controls all functions of the body. |
Resting Potential | Charge difference between the fluid outside and inside a cell that results in difference in the distribution of ions. |
Synapse | Junction between two neurons or between a neuron and an effector organ, where neural impulses are transmitted by electrical or chemical means. |
Trigeminal Neuralgia | Lesion of the trigeminal nerve involving facial pain. |
Olfactory nerve type | Afferent: nasal mucosa |
Optic nerve type | Afferent: retina of the eye |
Oculomotor nerve type | Efferent: eye muscles |
Trochlear nerve type | Efferent: eye muscles |
Trigeminal nerve type | Efferent: muscles of mastication and other cranial muscles. Afferent: face and head skin, teeth, oral cavity, parotid gland, and tongue. |
Abdunces nerve type | Efferent: eye muscles |
Faical nerve type | Efferent: muscles of facial expressions. Afferent: skin around ear and tongue |
Vestibulocochlear nerve type | Afferent: inner ear |
Glossopharyngeal nerve type | Efferenet: stylopharyngeus muscle and parotid gland. Afferent: skin around ear and tongue |
Vagus nerve type | Efferent: muscles of soft palate, pharynx, larynx, thorax, and abdominal organs. Afferent: skin around ear and epiglottis |
Accessory nerve type | Efferent: muscles of neck, soft palate, and pharynx. |
Hypoglossal nerve type | Efferent: tongue muscles. |

Which cranial nerve is directly involved in Bell palsy? | Facial nerve |
The hypoglossal nerve pairs with what muscle? | Intrinsic tongue muscles |
Which cranial nerve has fibers that provide crossover innervation to the contralateral side in the skull before continuing into the brain? | Optic nerve |
Which cranial nerve carries taste sensations for the base of the tongue | Glossopharyngeal nerve |
Which region of the head and neck is the trigeminal ganglion located? | Anterior surface of the petrous part of the temporal bone |
