Structure
The spleen has a slightly oval shape. It is covered by a weak capsule that protects the organ whilst allowing it to expand in size.
The outer surface of the spleen can be anatomically divided into two:
- Diaphragmatic surface – in contact with diaphragm and ribcage.
- Visceral surface – in contact with the other abdominal viscera.
It has anterior, superior, posteromedial and inferior borders. The posteromedial and inferior borders are smooth, whilst the anterior and superior borders contain notches.
In enlargement of the spleen (known as splenomegaly), the superior border moves inferomedially, and its notches can be palpated.
