Eye and ear are the Sense Organs. The former gives the ability to view by autofocusing the objects while the later gives The Sense of Hearing. So, what are the microstructures that make up these sense organs and make them capable of performing functions are discussed in this V-Learning™ lecture of Eye and Ear Histology. Primarily, focus is on the histology of cornea, iris, sclera, and ciliary body. Then all the structures of Retina are discussed including rods and cones in conjunction with inner ear, cochlea, and spiral organ of Corti.

At first, diagrammatic representation of eye is given which is followed by the ear. In the diagrams of eye and ear, the structures on which light is shed include Retina, cornea, iris, muller cells and semicircular canals, ear canal, and acoustic nerve respectively. Moving on to the histological illustration, the paraffin section of cornea comes under consideration demonstrating the Epithelium, fibroblasts, and collagen fibers.
The sample of sclera taken from monkey is also visualized under paraffin section highlighting the Blood vessel and melanocytes. Likewise, demonstration of paraffin section of iris, ciliary body, and tunics of the eye is given. Then, pars optica portion of the Retina, a photoreceptive part, taken from monkey sheds light on the structures like rods, cones, choroid, and optic nerve fiber layer when viewed under paraffin section.
Afterwards, microanatomy of fovea centralis, lens, and eyelid is also represented.Lacrimal gland illuminates the nucleus, serous acini, andConnective Tissue. Carrying on with the discussion, focus is shifted towards paraffin section of inner ear where vestibulocochlear nerve, auditory ossicle, spiral ganglion and associated structures are looked upon. Following this, cochlea highlights immense variety of structures under paraffin section along with spiral organ of Corti.
