Fоllоwing remоvаl of а mаndibular third molar, a patient has reduced sensation over the lower lip and chin on the operated side. Jaw-closing strength is normal.a) Identify the peripheral nerve supplying sensation to the lower lip and chin, and name the trigeminal division from which it arises. (2)b) Trace the main route by which nociceptive impulses from a mandibular tooth reach the primary somatosensory cortex. Include the sensory ganglion, main brainstem relay, crossing and thalamic relay. (5)c) Explain why normal jaw-closing strength is compatible with the sensory deficit described. (1)
