Fig. 7. Reconstruction model embryo 22 mm

B is a side view of the deeper structures in A after removal of the loose piece. The lighter portion of the cricoid and arytaenoid exhibit cartilaginous change, more advanced in the former. The chordal nodule is seen below and in front of the arytenoid, and, in front of this, the lateral edge of the wall of the transverse cavity passes upwards and outwards.

C is an outline of the thyroid ale. and its continuity with the greater cornu.

D gives the outline of the hyoid, thyroid, and inter-thyroid lamina, and cricoid from the front.

The numerous remaining structures in the last three models, with the other points that are evident in the earlier ones, will be described as they come into the account of the growth of the larynx.

A short general consideration of the floor of the pharynx can conveniently precede the description of the laryngeal development, with the object of showing that five arches are represented in this floor.

Online Editor - Embryo CRL 22 mm can be Week 8 Carnegie stage 20 or Carnegie stage 21.
