The gallbladder has three parts, the:

• Fundus: the wide blunt end that usually projects from the inferior border of the liver at the tip of the right 9^th costal cartilage in the midclavicular line (MCL).

• Body: main portion that contacts the visceral surface of the liver, transverse colon, and superior part of the duodenum.

• Neck: narrow, tapering end, opposite the fundus and directed toward the porta hepatis; it typically makes an S-shaped bend and joins the cystic duct.
