Which part of the gallbladder is located most inferior?

The fundus of the gallbladder is the portion that is located most inferiorly. It is the rounded, distal part of the gallbladder that projects away from the liver, making it the lowest point when the individual is in a supine position. Understanding the anatomy of the gallbladder is crucial for sonography, as it allows for better interpretation of images and identification of pathologies such as gallstones or inflammation. The neck of the gallbladder, on the other hand, is more superior and connects to the cystic duct, while the body is the central portion that lies between the fundus and the neck. Knowing the positions of these parts aids in procedural approaches and diagnoses during ultrasound examinations.
