Eyelids and conjunctiva Flashcards
The complex movable cover of the outer portion of the eyeball, consisting of an upper/lower component of skin, tarsus, delicate muscles, eyelashes, glands, and conjunctiva is
The eyelid
The almond-shaped opening between the upper and lower lids is the
Palpebral Fissure
The point where the lids meet on the nasal (inner) side of the palpebral fissure is the
Medial Canthus
The temporal (outer) junction of the lids is the
Lateral Canthus
This structure, also known as cilia, help protect the eye by sweeping away airborne dust particles and other foreign matter when the lids blink. These are the
Eyelashes
When an eyelash grows in the wrong direction and rubs the surface of the eye, irritating the cornea, it is called __________
Trichiasis
If a lash follicle becomes inflamed and produces a reddened, sore lump near the outer edge of the lid, it is called _________
Stye/External hordeolum
located on the posterior margin of the lid, there is a row of tiny holes, the openings of oil secreting glands hidden in the tissue of the lids called ________
Meibomian glands
Should a Meibomian gland become inflamed and infected, it may produce a swelling on the inner lid called _____
Internal hordeolum
Chronic inflammation resulting from an obstructed Meibomian gland may form a
Chalazion
A very common inflammation of the eyelid margin resulting in redness and crusting is called
Blepharitis
A dense plate-like framework, which gives eyelids their firmness and shape is called
The tarsus/tarsal plate
a circular muscle that closes the eye when is contracts is the
Orbicularis Oculi
When this muscle contracts, it raises the upper lid, this is the
Levator Palpebrae
When the upper lid droops and cannot lift fully it is a condition called
Ptosis
