Terminology for Praxis
| Term | Definition |
|---|---|
| Cranial Nerve I: Olfactory (1) | Sense of smell (sensory), originates in the nasal cavity |
| Cranial Nerve II: Optic (2) | Vision (sensory), originates in the retina |
| Cranial Nerve III: Oculomotor (3) | Eye movement (motor), originate in the midbrain are and innervates muscles corresponding to eye movement |
| Cranial Nerve IV: Trochlear (4) | Eye movement (motor) |
| Cranial Nerve V: Trigeminal (5) | Face (sensory); jaw (motor) |
| Cranial Nerve VI: Abducens (6) | Eye movement (motor) |
| Cranial Nerve VII: Facial (7) | Tongue (sensory); face (motor) |
| Cranial Nerve VIII: Acoustic (8) | Hearing and Balance (sensory) |
| Cranial Nerve IX: Glossopharyngeal (9) | Tongue and pharynx (sensory); pharynx only (motor), mixed nerve: Sensory, motor, autonomic component |
| Cranial Nerve X: Vagus (10) | Larynx, respiratory, cardiac, and gastrointestinal systems (sensory and motor) |
| Cranial Nerve XI: Spinal Accessory (11) | Shoulder, arm, and throat movements (motor) |
| Cranial Nerve XII: Hypoglossal (12) | Mostly tongue movements (motor) |
| Which cranial nerves are involved with speech, language, and hearing? | Cranial nerves V (Trigeminal), VII (Acoustic), IX (Glossopharyngeal), X (Vagus), XI (Spinal Accessory), XII (Hypoglossal) |
| What are the three branches of CN V Trigeminal? | 1.) Ophthalmic branch- sensory branches to the nose, eyes, and forehead 2.) Maxillary branch- sensory branches to the upper lip, maxilla, upper cheek area, upper teeth, maxillary sinus, palate. 3.) Mandibular branch- sensory branch- lower teeth, lip,etc |
| What is trigeminal neuralgia? | a sharp pain in the facial area |
| What do the motor fibers of CN V Trigeminal innervate? | various jaw muscles: temporalis, lateral and medial pterygoids, masseter, tensor veli palatini, tensor tympani, mylohyoid, and anterior belly of the digastric muscle |
| Which cranial nerves are mixed (sensory and motor)? | CN V (Trigeminal), VII (Facial), IX (Glossopharyngeal) |
| What would damage to CN V (Trigeminal) cause? | inability to close the mouth, difficulty chewing, and trigeminal neuralgia |
| What would damage to CN VII (Facial) cause? | Person has a mask-like appearance with minimal to no facial expression |
| What would damage to CN VIII (Acoustic- Vestibulocochlear) cause? | Results in hearing loss, problems with balance, or both |
| What would damage to CN IX (Glossopharyngeal) cause? | Lesions of the glossopharyngeal nerve may create difficulty in swallowing, unilateral loss of the gag reflex, and loss of taste and sensation from the posterior third of the tongue |
| What would damage to the CN X (Vagus) cause? | a difficulty swallowing, paralysis of the velum, and voice problems if the recurrent laryngeal nerve is damaged |
| What would damage to the CN XI (Spinal Nerve Accessory) cause? | may result in neck weakness, paralysis of the sternocleidomastoid, and consequently inability to turn the head, as well as inability to shrug the shoulder or raise the arm above shoulder level |
