Abdominal Surgery
Names the two types of stitches
Continuous and Interrupted
Name the 3 directions for surgical Incisions
Vertical, Horizontal, Oblique
A cut made intentionally with a knife in surgery?

Dehiscence
These wounds are not planned and are due to injury
Traumatic Wounds
During what phase does actual healing take place?

Cornea, Sclera, Choroid
Eye Surgery

Thoracic/Cardiac Surgery
What is a disadvantage to a continuous stitch?
If suture breaks, whole wound may come open

Maturation or remodeling phase
Skin, Galea, Meninges
Cranial Surgery
What is the surgeons ultimate goal during closure?
Hold several tissues together (in proximity) with mechanical means until the wound has healed enough to withstand stress without mechanical support.
