The term "sustentaculum lieni" is a Latin phrase that translates to "support of the spleen" in English. It refers to a bony structure found in the human body specifically within the tarsal region of the foot.
Anatomically, the sustentaculum lieni is part of the calcaneus bone, the largest tarsal bone that forms the heel of the foot. It is a thick, bony platform that projects from the medial (inner) side of the calcaneus. Positioned superiorly and forwards, it creates a concave area between itself and the talus bone, a major bone in the ankle joint.
The primary function of the sustentaculum lieni is to provide support and stability to the spleen, one of the vital organs in the human body. The ligaments that maintain the position of the spleen attach to the sustentaculum lieni, keeping it in place and preventing it from excessive movement.
In addition to its role in supporting the spleen, the sustentaculum lieni also plays a crucial role in weight-bearing and load distribution during walking, running, and other weight-bearing activities. It forms a significant part of the medial arch of the foot, contributing to its strength and resilience.
Overall, the sustentaculum lieni is an anatomical structure that is essential for the proper functioning of the foot as well as the support and secure positioning of the spleen within the abdominal cavity.
The word "sustentaculum lieni" is derived from Latin.
1. "Sustentaculum" comes from the Latin verb "sustentare", which means "to sustain" or "to support". It is a combination of "sus-" (meaning "under") and "teneo" (meaning "I hold"). Therefore, "sustentaculum" can be translated as "something that holds or supports from below".
2. "Lieni" is the genitive form of "lien", which comes from the Latin word "liene", meaning "spleen", referring to the organ in the human body.
So, "sustentaculum lieni" can be translated as the "supporting structure of the spleen".
