Applied Anatomy
- The upper part of the lacrimal sac is covered by the medial palpabral ligament. Hence the abscesses within the sac bulge below the medial palpabrel ligament, where it should be incised for letting out the pus.
- The angular vein is in front of the sac and it should be take care during incising the sac. Between the lacrimal sac and the fascia coverning the sac there is the collection of venous plexus present hence the incising causes considerable bleeding.
- Around the nasolacrimal duct there is the rich plexus of veins, in the form of an erectile tissue, which may engorge and cause obstruction to the duct.

Famous quotes containing the words applied and/or anatomy:
“Those who dare to interpret God’s will must never claim Him as an asset for one nation or group rather than another. War springs from the love and loyalty which should be offered to God being applied to some God substitute, one of the most dangerous being nationalism.”
—Robert Runcie (b. 1921)
“I love to see, when leaves depart,
The clear anatomy arrive,”
—Roy Campbell (1902–1957)
