Motor to small throat and mouth muscles.
Besides the stylopharyngeus muscle, what else does cn ix innervate? Our increasing knowledge about nerve physiology and regeneration far outweighs our surgical abilities to reconstruct damaged nerves and successfully regenerate motor and sensory function. Neuralation begins at the trilaminar embryo with formation of the notochord within the mesoderm that underlies the ectoderm and do not physically contribute to the nervous system. Mandibular • maxillary • chorda tympani (pretrematic nerve) chorda tympani supplies anterior 2/3 of mucosa of tongue which is developed opposite the fist arch reichert's pouch second pouch third pouch fourth pouch dr.

Develops into thymus and inferior.
While under the trapezius, the medial branch of the posterior division of the third cervical nerve gives off a branch called the third occipital nerve (also known as the least occipital nerve), which pierces the trapezius and ends in the skin of the lower part of the back of the head. Each arch has its own cranial nerve with both afferent and efferent branches innervating the arch itself (an additional afferent pretrematic branch is found in the adjacent, rostral arch). In each pharyngeal arch there is an artery, a nerve, and a skeletal member. The c3 dorsal ramus has both a medial and a lateral portion and furthermore, the medial portion has a superficial and a deep segment. What are the 3 pretrematic nerves, where they derive. Besides the stylopharyngeus muscle, what else does cn ix innervate?
