What is Branch of facial nerve conveying secretomotor fibers to the lacrimal gland is? and explain in detail?
The greater (superficial) petrosal nerve carries parasympathetic preganglionic fibers from the facial nerve. The greater petrosal nerve continues as the nerve of the pterygoid canal and ultimately synapses with the pterygopalatine ganglion whose parasympathetic postganglionic fibers synapse with the lacrimal gland and the mucosal glands of the nose, palate, and pharynx.
