Visual Acuity and Optical Defects

If a personĀ  can read letters at 20 feet that are readable at that distance to all people with normal vision, that person's visual acuity, or "eyesight", is said to be 20/20. If, on the other hand, a person is barely able to read letters at 20 feet that are readable at 40 feet to all people with normal vision.

Astigmatism
Astigmatism is a condition characterized by "blemishid vision"; that is, instead of light rays striking the retina in sharp focus, they spread out over a more or less diffuse area. Astigmatism is caused by the unequal curvature of either the cornea or the lens, sometimes both. Because the cornea and lens, are never optically perfect, most of us experience some degree of astigmatism. To correct astigmatism, the ophthalmologist prescribes glasses that compensate for the faulty curvatures of the refracting surfabes

The Ear, the organ of sound and balance

The ear is divided into the outer, middle, and inner parts. The outer ear consists of the auricle and the auditory canal. The middle ear, a small chamber lying within the temporal bone and separated from the outer ear by the eardrum (tympanic membrane), houses the ossicles (three tiny bones bearing the names malleus, incus, and stapes) and communicates with the upper throat via the eustachian tube.

The inner ear consists of the outer osseous labyrinth enclosing the inner membranous labyrinth, whose parts are the cochle, semicircular canals, utricle, and saccule. A watery fluid, the perilymph, fills the space between the osseous and membranous labyrinths, and another watery fluid, the endolymph, fills the membranous labyrinth. The organ of Corti, the actual receptor of sound, is situated within the cochlea.

Neurons And Nerves

The human body contains a dozen billion nerve cells (neurons) interwoven into what we call the brain and spinal cord. The basic unit of the nervous system is theĀ  neuron, which consists of a cell body and branched extensions, or processes. Dendrites are those processes conducting nerve (electrical) impulses to the cell body, and axons are those processes conducting nerve impulses away from it. Sensory neurons conduct nerve impulses to or toward the central nervous system; motor neurons conduct nerve impulses to the muscles, glands, and organs; and connector neurons conduct impulses from sensory to motor neurons.

Whereas the sensory neuron typically has long dendrites and a short axon, the motor neuron has short dendrit and a long axon; connective neurons generally have short processes. The junction between the terminal endings of the axon of one neuron and the dendrites of another is referred to as a synapse.
