Plate 20, Figures 59-64.
Fig. 59. Dorsal view of the
left eye in situ, after the orbit has been opened, and the dorsal wall bent to
the side. The optic sinus has been opened by cutting a window through the
membrane (E.A.) which attaches the eye to the skull. Part of the white body (W.B.)
can be seen Iying in the sinus.
Fig. 60. Mesial view of the
left eyeball as seen from a slightly dorsal aspect. The membrane (E.A.)
holding the eye to the cartilaginous part of the orbit has been cut away close
to the eye. All the extrinsic muscles of the eye which are attached to this
membrane were cut away at the same time, except for the trochlear muscle III (M.TR.
III.) which is inserted on the inner ventral surface of the sclerotic
cartilage (SC.CA.). The end of the ophthalmic artery (O.A.) has been left in
place. The retinal nerves have been cut through close to the sclera through
which they pass by means of numerous foramina (F.R.N.).
Fig. 6I. Dorsal view of the
eyeball attached to the skull, to show the superior oculomotor muscles.
Fig. 62. Posterior view of the
eyeball attached to the skull, to show the posterior oculomotor muscles.
Fig. 63. Ventral view of the
eyeball attached to the skull, to show the inferior oculomotor muscles.
Fig. 64. Mesial anterior view
of the eyeball attached to the skull, to show the conjunctive and trochlear
oculomotor muscles.
Fig.
65. Mesial anterior view of the eyeball attached to the skull. The
trochlear cartilage has been cut off, and the conjunctive oculomotor muscles,
and the trochlear oculomotor muscles I and II removed, to show the anterior
oculomotor muscle I (M.A., I.) and the trochlear oculomotor muscle III (M.TR.,
III).
