Fig.4. Diagram representing the growth and stages of differentiation of the human membranous labyrinth

A resume of the development of the labyrinth is presented in the form of a diagram in the adjacent Fig. 4, which illustrates the successive steps by which the simple ear vesicle enlarges and becomes differentiated into the group of connected individual compartments which characterize the adult ear.

3.5 weeks 4 weeks 5 weeks 6 weeks 10 weeks
(6-7 mm) the ear vesicle consists of two simple pouches, into the upper of which opens the endolymphatic appendage. (9 mm) there is at the base of the vestibular pouch an atrium, the space destined to form the utricle and saccule. (12 mm) this space is circumscribed from the cochlear pouch below by a constriction corresponding to the ductus reuniens, and above from the rest of the vestibular pouch by the formation of the semicircular canals. (20 mm) an ingrowth of the wall of the atrium divides it into an upper part (utricle) and lower part (saccule). (30 mm) this partition between the utricle and saccule is complete and extends inward in such a way as to split the orifice of the endolymphatic duct.
