buccopharyngeal

With the further expansion of the brain, and the forward bulging of the pericardium, the buccopharyngeal membrane is depressed between these two prominences.

It is lined by ectoderm, and is separated from the anterior end of the fore-gut by the buccopharyngeal membrane.

In A the buccopharyngeal membrane is still present.

In front of the buccopharyngeal area, where the lateral crescents of mesoderm fuse in the middle line, the pericardium is afterward developed, and this region is therefore designated the pericardial area.

This diverticulum, pouch of Rathke (Fig. 1182), is the rudiment of the anterior lobe of the hypophysis; it extends upward in front of the cephalic end of the notochord and the remnant of the buccopharyngeal membrane, and comes into contact with the under surface of the fore-brain.

In A the buccopharyngeal membrane is still present.

Parallel to the carotid sheath and along its medial aspect the prevertebral fascia gives off a thin lamina, the buccopharyngeal fascia, which closely invests the Constrictor muscles of the pharynx, and is continued forward from the Constrictor pharyngis superior on to the Buccinator.

IV. Myology. 5b. The Lateral Cervical Muscles 1918

The lymphatic vessels of the palatine tonsil, usually three to five in number, pierce the buccopharyngeal fascia and constrictor pharyngis superior and pass between the Stylohyoideus and internal jugular vein to the uppermost of the superior deep cervical glands.

VIII. The Lymphatic System. 3. The Lymphatics of the Head, Face, and Neck 1918

The retropharyngeal glands (Fig. 603), from one to three in number, lie in the buccopharyngeal fascia, behind the upper part of the pharynx and in front of the arch of the atlas, being separated, however, from the latter by the Longus capitis.

VIII. The Lymphatic System. 3. The Lymphatics of the Head, Face, and Neck 1918

Over this area the ectoderm and entoderm come into direct contact with each other and constitute a thin membrane, the buccopharyngeal membrane, which forms a septum between the primitive mouth and pharynx.
