There are two important foramina, or windows, two important fissures, or grooves, and one canal surrounding the globe in the orbit. There is a supraorbital foramen, an infraorbital foramen, a superior orbital fissure, an inferior orbital fissure and the optic canal, each of which contains structures that are crucial to normal eye functioning.
The longest appendix ever removed was 26 cm (10 in) long. [3] The appendix is usually located in the lower right quadrant of the abdomen, near the right hip bone. The base of the appendix is located 2 cm (0.79 in) beneath the ileocecal valve that separates the large intestine from the small
The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis.
The accessory visual structures (or adnexa of eye, ocular adnexa, etc.) are the protecting and supporting structures of the eye, including the eyebrow, eyelids, and lacrimal apparatus. The eyebrows, eyelids, eyelashes , lacrimal gland and drainage apparatus all play a crucial role with regards to globe protection, lubrication, and minimizing ...
Press down with firm pressure on your left lower quadrant, the opposite side to where the appendix is. If you experience worsening pain in your right lower quadrant, this is a sign the lining of ...
The orbital septum is an important structure that separates anterior and posterior extent of the orbit. Orbital septum acts as a physical barrier that prevents the infection of the anterior part of the eye spreading posteriorly. For example, preseptal cellulitis mainly infects the eyelids, anterior to the orbital septum.
The corneal limbus may be cut to allow for aqueous humour to drain from the anterior chamber of the eye into the subconjunctival space. [5] This can be used in glaucoma treatment. [ 5 ] The hole created only needs to be small, although slightly bigger than needed to account for gradual healing. [ 5 ]
The strongest part of a hurricane is typically the right front quadrant, where winds blow in the same direction that the hurricane is moving, resulting in stronger winds and increased storm surge.
