Questions fréquentes

What is an organ part and how does it differ from an organ subunit?
An organ part is a multicellular structure that is a component of an organ but does not necessarily constitute a complete modular functional unit. Unlike organ subunits (which are repeating functional modules), organ parts may be anatomically distinct regions or structural components of an organ — for example, the head, body, and tail of the pancreas, or the apex and base of the heart. These parts are defined by their spatial position or structural identity rather than being repeating functional modules.
What are examples of organ parts in the human body?
Examples of organ parts include: the cortex and medulla of the kidney (anatomically and functionally distinct regions within one organ), the fundus and pylorus of the stomach, the ascending and descending colons (regional parts of the large intestine), the right and left atria of the heart, and the anterior and posterior lobes of the pituitary gland. Each is a definable multicellular region within a larger organ.
Why is distinguishing organ parts important clinically?
Many diseases or injuries affect specific organ parts selectively rather than the entire organ. Renal cell carcinoma may arise specifically in the cortex, while transitional cell carcinoma arises in the renal pelvis — two organ parts of the same kidney requiring different management. Gastric ulcers in the pylorus versus the fundus have different acid-secretory causes and consequences. Organ-part specificity guides targeted diagnosis, biopsy, and treatment.
