Consists of ocular bulbs (eyeballs) with associated extraocular muscles located in orbits. Nerves: olfactory nerve (CN I), ophthalmic nerve (CN V1), maxillary nerve (CN V2) Eye. Arteries: facial, sphenopalatine, greater palatine, and ophthalmic arteries. ![]() When you are happy with your selection, use the ‘Check answers’ button to check them.

Otoacoustic emissions (OAE) test: During this test, sounds are emitted by the vibrations of hair cells in response to a. Drag and drop the text labels onto the boxes next to the eye diagram Auditory brainstem response (ABR) test: A test of inner ear function (as well as neural pathways from there), this examination involves using electrodes placed on the skin to measure brain activity in response to stimuli. Use your mouse or finger to hover over a box to highlight the part to be named. Air or water is instilled into the ear canal at different temperatures to stimulate the inner ear. In the middle ear are three tiny bones: malleus, incus, and stapes, collectively known as the ossicles.These form a bridge from the eardrum to the inner ear. In this interactive, you can label parts of the human eye. ![]() This stimulates the visual centres in the brain, giving us the sensation of seeing. The human eye has several structures that enable entering light energy to be converted to electrochemical energy. Although it’s not obvious to look at, the ear is anatomically divided into three portions: External (outer) ear Middle ear Inner ear As you can imagine, there’s a lot of associated anatomy to learn for each portion With that in mind, this article will focus on learning the anatomy of the external (outer) ear.
