- Toward the tail; backward in the long axis of the body; in the opposite direction from cephalad.
Figure 4H is seventy-nine sections posterior to the last, and passes through the foregut, _ent_, just cephalad to the anterior intestinal portal and caudad to the heart.
A series of transverse sections caudad to the preceding.
In the most posterior of these four sections of the tail, beginning slightly caudad to the section here shown, is seen a small cavity which may be called the post-anal gut,
The duodenum extends only a short distance caudad to this point and then opens, _aip_, to the yolk-sac.
The duodenum, _d_, makes a U-shaped bend at the side of the stomach, and then, in the region of the caudal edge of the gizzard, _gz_, dips suddenly ventrad and caudad towards the umbilical cord, _u_, where it apparently ends blindly, though this appearance is probably due to an artifact in the embryo from which the reconstruction was made.
Two or three sections caudad to the one just described, the two layers of which the tongue of cells from the floor of the pharynx is composed separate slightly at the bottom to form a small cavity, the trachea,
A short distance caudad to this region the groove disappears and the pharynx is reduced to a shallow slit extending almost to the superficial ectoderm on either side; then the slit-like pharynx becomes suddenly reduced in a lateral and increased in a dorso-ventral direction, to assume the outline shown in figures 3B and
The character of the epithelium of the enteron caudad to the pharynx will be discussed in connection with the sections to be described below.
Followed caudad the dorso-ventral diameter of the oesophagus varies somewhat, as does the lateral diameter, but it remains large throughout and opens into the stomach with no sharp line of demarkation.
Close to the sides of the thyroid are seen two large blood vessels, _ar_, the mandibular arches, which unite into the single ventral aorta just caudad to the posterior end of the thyroid.
