Eyelid: Palpebral conjunctiva
-conjunctival fornix |
I. Eyelid and Lacrimal Apparatus
A. Eyelid 1. Palpebral conjunctiva: mucosa covering the posterior surface of the eye- lid; it turns back on itself at a region called the conjunctival fornix and becomes continuous with the bulbar conjunctiva covering the anterior part ofthe sclera or "white of the eye" |
|
Eyelid: TARSUS
what does it border? attachments? |
I. Eyelid and Lacrimal Apparatus
A. Eyelid 2. Tarsus: semilunar plate of dense connective tissue between the palpe- bral conjunctiva and superficial fascia; borders the free margin of the eyelid and attaches to the medial and lateral walls ofthe orbit, just in- side the orbital margin, via the medial and lateral palpebral ligaments, respectively |
|
Eyelid: TARSAL GLANDS
|
I. Eyelid and Lacrimal Apparatus
A. Eyelid 3. Tarsal glands: modified sebaceous glands within a tarsus; their ducts open on the free margin of the eyelid and their oily secretion forms a surface film that reduces evaporation of lacrimal fluid |
|
SUPERIOR TARSAL MUSCLE
-location? attachment? -receives sympathetic inn.? -how does it contract? |
4. Tarsal muscles
a. Superior tarsal muscle: smooth muscle within the tendon of levator palpebrae superioris that attaches to the tarsus ofthe upper eyelid; receives sympathetic innervation from the internal carotid plexus and contracts reflexly to elevate the upper eyelid |
|
INFERIOR TARSAL MUSCLE
-from where to where does it extend? -function? |
b. Inferior tarsal muscle: smooth muscle extending from the tarsus of
the lower eyelid to the fascial sheath of the inferior rectus muscle; its function is unknown |
