Articulation talocalcaneonavicularis refers to a specific joint found in the human foot. It is also known as the talocalcaneonavicular joint or the TCN joint. This joint is located between the talus bone, the calcaneus bone, and the navicular bone.
The talus bone, which is positioned at the top of the foot, connects the leg bones (tibia and fibula) to the foot bones. The calcaneus bone, commonly referred to as the heel bone, is the largest bone in the foot and is adjacent to the talus bone. Lastly, the navicular bone is located near the middle portion of the foot, connecting the talus bone to the cuneiform bones.
The articulation talocalcaneonavicularis allows for movements and provides stability to the foot during weight-bearing activities such as walking, running, and jumping. It is a synovial joint, meaning it contains a fluid-filled cavity which reduces friction between the bones during movement.
This joint permits a variety of movements, including plantarflexion (pointing the foot downwards), dorsiflexion (bringing the foot upwards), inversion (turning the sole of the foot inward), and eversion (turning the sole of the foot outward).
Dysfunction or injury to the articulation talocalcaneonavicularis can result in foot pain, swelling, or limited range of motion. Proper diagnosis and treatment, often involving physical therapy or orthopedic interventions, are necessary to restore normal joint function and alleviate symptoms.
Articulation between the talus, or astragalus, the calcaneus, or os calcis, and the navicular, or scaphoid bone.

The word "articulation talocalcaneonavicularis" is derived from Latin and Greek roots. Here is the breakdown:
1. "Articulation": This comes from the Latin word "articulus", meaning joint.
2. "Talo-": This is a prefix referring to the talus bone, which is one of the tarsal bones found in the foot.
3. "Calcaneo-": This is a prefix referring to the calcaneus bone, also known as the heel bone.
4. "-navicularis": This suffix is derived from the Latin word "navis", meaning ship, and it refers to the navicular bone, which is another tarsal bone in the foot.
Combined, "articulation talocalcaneonavicularis" refers to the joint formed between the talus bone, calcaneus bone, and navicular bone in the foot.
