The anterior division of the mandibular nerve contains______________?
Show answer Hide answer
Answer: A. One sensory and all motor branches
Explanation
The anterior division of the mandibular nerve carries mostly motor branches along with one sensory branch. The long buccal nerve provides the sole sensory contribution within this predominantly motor nerve division. Anatomical tracing reveals that motor fibers dominate the nerve trunks exiting through the anterior division pathway. The mandibular nerve represents the third division of the trigeminal cranial nerve exiting via foramen ovale. Motor branches from the anterior division supply several key muscles of mastication in the infratemporal fossa. The long buccal nerve pierces the heads of the lateral pterygoid muscle to reach the cheek mucosa.
One sensory and all motor branches incorrectly describes the posterior division which is mostly sensory. All motor branches is inaccurate because the division distinctly includes the sensory long buccal nerve. All sensory branches describes the ophthalmic and maxillary divisions rather than the mixed mandibular division.
