And the monitor should be slightly tilted back (about 10Â° - 15Â°) so that when you are looking at the center of the screen your line of sight is perpendicular to the surface of the screen.f only the lower portion of your glasses will allow you to see the monitor in focus, then obviously the monitor should be located at a height that will allow you to maintain your head at a comfortable vertical position which does not go beyond 90Â° (i.e. bending your head back).
The long ciliary nerves provide sensory innervation to the eyeball, including the cornea. In addition, they contain sympathetic fibers from the superior cervical ganglion to the dilator pupillae pupillÃ¦. musclehe sympathetic fibers to the dilator pupillae muscle mainly travel in the nasociliary nerve but there are also sympathetic fibers in the short ciliary nerves that pass through the ciliary ganglion without forming synapses.
The microscopic olfactory cilia play a very important role in the perception of smell, and they perform several other functions for the nose as well. Properly speaking, the visible nose hair is just hair, not cilia.Cilia are specialized biological structures which closely resemble hair, but on a much smaller scale.d. The olfactory cilia inside the nose line the mucus membranes of the nose, and unlike most other cilia in the body, they are non-motile, remaining stationary in the nose rather than wiggling around in the mucus like the cilia which line the trachea and intestines do.
