45. Tongue develope from: 1/mandibular arch & tuberculum impar. *** 2/1st branchial arch
Anatomy of the Human Body - Henry Gray – page 27 - The mandibular arch lies between the first branchial groove and the stomodeum; from it are developed the lower lip, the mandible, the muscles of mastication, and the anterior part of the tongue. - The ventral ends of the second and third arches unite with those of the opposite side, and form a transverse band, from which the body of the hyoid bone and the posterior part of the tongue are developed. Anatomy of the Human Body - Henry Gray – page 693
During the third week there appears, immediately behind the ventral ends of the two halves of the mandibular arch, a rounded swelling named the tuberculum impar, which was described by His as undergoing enlargement to form the buccal part of the tongue. More recent researches, however, show that this part of the tongue is mainly, if not entirely, developed from a pair of lateral swellings which rise from the inner surface of the mandibular arch and meet in the middle line.

The pancreas is a gland organ in the digestive and endocrine system of vertebrates. It is both an endocrine gland producing several important hormones, including insulin, glucagon, andsomatostatin, as well as an exocrine gland, secreting pancreatic juice containing digestiveenzymes that pass to the small intestine.

The third part of maxillary artery gives branches which correspond to the branches of the maxillary nerve and the branches of the spheno-palatine ganglion. *Branches of the sheno-palatine ganglion:
-greater palatine…………..supply hard palate. -lesser palatine……………supply soft palate. -long spheno- palatine…….anterior part of hard palate The blood supply of the palate is provided anteriorly through the incisor foramen and posteriorly through the great palatine foramen where the great palatine artery emerges . The blood supply of the palate is from ascending branches of the facial artery as well as from the branch of the maxillary artery, The palatine vessels and nerves pass through the palatine canal. The greater palatine artery was the main vessel to supply the hard palate and the ascending palatine artery provided the principal supply of s oft palate. The branches of greater palatine artery formed abundant anastomoses with the neighbor vessels.
