Eyeball Anatomy sculptures and prints through the ages. Eyeball anatomy as it relates to eye diseases.
This diagram illustrates other important relationships essential for conjugate gaze and the regulation of the vestibular-ocular reflex. An essential element in this relationship includes vestibular inputs to vestibular nuclei (6). Vestibular nuclei project to the ipsilateral cranial nerve (CN) VI, which is inhibitory, and to the contralateral CN VI, which is excitatory (3). Projections from CN VI to the contralateral CN III are also excitatory (7). The medial longitudinal fasciculus contains fib
Origin and distribution of the trochlear nerve (cranial nerve IV) to the superior oblique muscle. As indicated in the cross section of the brainstem, note that this nerve exits the brain from the dorsal aspect, and it is the only nerve that is crossed. Arrow indicates direction of movement of the bulb downward and inward.
Origin and distribution of cranial nerves (CN) VI, IV, and III, which innervate extraocular eye muscles. The focus of the upper part of this figure includes the abducens nerve (CN VI) and the general somatic efferent component of the oculomotor nerve (CN III), which are essential for horizontal gaze. The lower part of this figure depicts the muscles of the eye and their relationship with CN III, IV, and VI.
Zacharias Traber’s (1611-1679) beautifully illustrated classic of optics (and physiological optics) , Nervus Opticus sive Tractatus Theoricus…, published in Vienna in 1690. Traber is a great collector and synthesizer of the work done during and before his time, using the work of Descartes, Kepler, Schott, Kircher, Scheiner and Aguilon (for example), and then further implementing their ideas especially in the areas of color theory and light refraction.
