Orgin
Emerges frin the anterolateral aspect of the pons, apart of the brainstem.
Location:
Pons;Brainstem
Pathway:
V1- OpthalmicV2- Maxillary V3- Mandibular Carry input from different facial regions
Cranial Nerve V: Trigeminal
Senotr/Motor/Both:
Emerges from the pons by two roots of unequal size: a small motor root and a lage senspry root.
Facial Sensation (Pain, Temperature, touch) -Muscle Mastication
Damages: Effects & Regenerate
Damage to the cranial nerve may result in facial numbness, pain, tingling, and weakness in the chewong muscleRegeneration: Mild- Ie- nerve compression; The axons can regernerate overtime Severe: Ie- axonotemesis may not recover on it own
Surgical Precautions:
microscopic guidance teflon padding precise positioning minimal tissue manipulation intraoperative monitoring
Orgin
Orginates from the caudal in the lower back part of the pons, just dorsal to the fourth ventricle of the brain
Location:
Resides in the dorsal pons, ventral to the floor of the fourth ventricle, and lateal to the medial longitudinal fasciculus.
Pathway:
Begins in the lower back part of the pons, travels forward through the brainstem, passinf through the cavernous sinus and supeior orbital fissure and then reaches the lateral rectus muscle to move the eye outward.
Cranial Nerve VI: Abducens
Senory/ Motor/Both?
soley somatomotor nerve abduction
Damages: Effects & Regenerate
To innervate the lateral rectus muscle, which is responsible for abduction- moving the eye outward- on the same ipsilateral side.
Damage to the abducens can be caused by anything that compresses or stretches it. ie- Sixth nerve palsy Regeneration: mild damage can regernerate with many cases resolving within 3-6 months Severe Damage have several treatment options; prims glasses, eye patches, botox, stabismus surgery
Surgical Precaution
Electrophysiological monitoring Hemostasis and thermal protection Prevention of excessive traction
