Though known as the second cranial nerve, it is considered part of the central nervous system. Each eye has multiple layers and chambers and is surrounded by 6 extraocular muscles. Layer containing blood vessels that lines the back of the eye and is located between the retina (the inner light-sensitive layer) and the sclera (the outer white eye wall). The iris is partly responsible for regulating the amount of light permitted to enter the eye. Review our resources for guidelines about COVID-19. These three layers together are called the tear film.

Central retinal artery occlusion presents with sudden, profound loss of vision. The junction between 2 neurons is called a synapse. The human eye is a Most of these fibers originate from cells of the trigeminal ganglion and project to the trigeminal nucleus of the brain stem. Build your base for a thorough . Arteries are tubular collections of cells that transport oxygenated blood and nutrients from the heart to the tissues of the body. Dissection then shifts to the internal anatomy of the eyeball. Cornea. Originates in the hypothalamus and descends to the first synapse in the cervical spinal cord, located at levels C8T2 (also called the ciliospinal center of Budge). Anatomy of the Eye. The primary visual pathway consists of a relay system, beginning at the retina, whose ganglion cell axons form the optic nerve. The clear, dome-shaped surface that covers the front of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. Individuals commonly have between 4 and 8 vortex veins. Much research has shown the benefits of additional anatomical learning and dissection beyond the first year of medical school human gross anatomy, all the way through postgraduate medical training. In this interactive case you will learn about evaluating a patient who presents with a systemic disease, and when to refer a patient to an ophthalmologist.

Type 2 DM has a significant association with obesity and is characterized by insulin resistance. Here, the two optic nerves unite to form the optic chiasm. vision Emission or propagation of acoustic waves (sound), electromagnetic energy waves (such as light; radio waves; gamma rays; or x-rays), or a stream of subatomic particles (such as electrons; neutrons; protons; or alpha particles). Retina. The nerve carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain.
