How Do You Spell SINUS TARSI?

1. Sinus tarsi is a term used in anatomy to describe a small hollow cavity located on the outer side of the foot, specifically between the talus bone of the ankle and the calcaneus bone of the heel. The term "sinus tarsi" is derived from Latin, with "sinus" meaning a hollow or cavity, and "tarsi" referring to the part of the foot between the ankle and the heel.

   The sinus tarsi is located within a bony groove formed by the talus and calcaneus bones. It is an important anatomical structure as it provides a passage for numerous ligaments, tendons, and nerves that support the foot and enable its movement and sensation.

   This hollow cavity is covered by a protective layer of connective tissue known as the interosseous talocalcaneal ligament. The sinus tarsi also contains a small amount of fatty tissue, which provides cushioning and support to the surrounding structures.

   Disorders or injuries involving the sinus tarsi can cause pain, inflammation, and restricted movement of the foot. These conditions may include sinus tarsi syndrome, which is characterized by tenderness, swelling, and instability in the area. Treatment for such conditions typically involves rest, physical therapy, and in severe cases, surgical intervention may be necessary to address any underlying causes.

   Overall, the sinus tarsi is a crucial anatomical feature in the foot that ensures proper movement, stability, and overall function of the lower limb.

2. Tarsal s., a hollow or canal formed by a broad groove in the talus, just anterior to the posterior articular facet (sulcus tali), and a corresponding groove in the calcaneus (sulcus calcanei).

Common Misspellings for SINUS TARSI

The term "sinus tarsi" has its roots in Latin.

The word "sinus" in Latin referred to a cavity, hollow, or a bend. In this context, it refers to the hollow space found on the lateral (outer) side of the ankle joint.

The word "tarsi" comes from the Latin word "tarsus", which denotes the bones forming the back part of the foot. These are the bones located between the leg and the metatarsal bones (bones that make up the front part of the foot).

Therefore, "sinus tarsi" refers to the hollow space found between the tarsal bones, particularly on the lateral side of the ankle joint.
