TIBIALIS POSTICUS Meaning and
Definition
-
The term "Tibialis Posticus" refers to a muscle located in the lower leg, specifically the posterior compartment, which lies deep beneath the calf muscles. It is part of a group of muscles called the deep posterior compartment muscles. The Tibialis Posticus muscle originates from the back part of the tibia bone and the surrounding interosseous membrane, which connects the tibia to the fibula.
Functionally, the Tibialis Posticus acts as a powerful ankle plantarflexor, meaning it is primarily responsible for pointing the foot downwards. Additionally, it plays a crucial role in foot inversion, aiding in turning the sole of the foot inward. This muscle is especially important in maintaining stability and balance during walking, running, and other weight-bearing activities.
The Tibialis Posticus muscle is enclosed within a tough sheath called the tibialis posterior tendon. This tendon extends from the muscle belly down around the inside aspect of the ankle, running underneath the medial malleolus bone, and attaches to several bones in the midfoot. Its attachment to various bones allows it to provide support to the arch of the foot, assisting in maintaining its shape and preventing excessive flattening (pronation) during weight-bearing activities.
In summary, the Tibialis Posticus is a deep posterior compartment muscle of the lower leg that primarily functions to plantarflex the ankle and invert the foot. Its actions are crucial in providing stability and balance during locomotion, while also contributing to maintaining the integrity of the foot's arch.

Etymology of TIBIALIS POSTICUS
The word "Tibialis Posticus" is derived from Latin. Here's a breakdown of its etymology:
1. Tibialis: It comes from the Latin word "tibia", which means "shinbone". The word "tibialis" refers to the muscle located near the tibia or shinbone.
2. Posticus: It is derived from the Latin word "post", meaning "after" or "behind". The suffix "-icus" indicates belonging or related to. Therefore, "Posticus" means "behind" or "situated at the rear".
Put together, "Tibialis Posticus" refers to the muscle situated at the rear of the tibia or shinbone.
