Plate 4. Four drawings of a model of the eye, eye-muscle primordia, and associated nerves

Embryo No.6258, horizon xvii.

Fig. 15. A portion of the brain, the eye, principal nerves, peripheral condensations, and the eye—muscle primordia. Dorso-lateral aspect. No. 6258, X 30.


Attention is called to the four peripheral condensations, about the outer margin of the optic vesicle, into which the primordia of the four rectus muscles have grown. Cranial nerves III, IV, and VI have reached their respective eye-muscle primordia: the primordium of the inferior oblique has appeared as a conspicuous condensation at the distal end of the inferior rectus; a prominent bend (at the point where the trochlea will subsequently develop) has appeared near the distal end of the superior oblique primordium, and the proximal end of the superior oblique has begun to shift medially.
