<prompt> Intrinsic muscles of the tongue are derived from ?2nd branchial cleftPharyngeal arch mesenchymeOccipital somitesCervical somites  <response>: The occipital somites four to five give rise to muscles of the tongue. The tongues embryonic origin is derived from first 4 pharyngeal arches contributing different components. Anterior 23rd or body of tongue is derived from 3 lingual buds the median tongue bud tuberculum impar and 2 lateral lingual swellings developing at each side of the median tongue bud. 23rd of the tongue originates from the first pharyngeal arch. Sensory innervation to this area is by the mandibular branch of the trigeminal nerve. Taste sensation to the anterior 23rd of the tongue is provided by the chorda tympani branch of the facial nerve. Post 13rd or root of the tongue is formed from two median elevations. Ref: Human Embryology INDERBIR SINGH 6th Ed Page 98,156.
