The tarsal bones contain several joints, including the talocrural, talocalcaneal, talonavicular, calcaneocuboid, and navicularcuboid joints.
The question "Which joint is present in tarsals?" is somewhat broad because the tarsus (ankle) contains multiple bones that articulate with each other and with bones of the lower leg and foot. Here's a more detailed breakdown:
Tarsal Bones and Their Joints
The tarsus is composed of the following bones: talus, calcaneus, navicular, and cuboid. These bones form several important joints:
- Talocrural Joint (Ankle Joint): This joint connects the talus with the tibia and fibula of the lower leg, facilitating dorsiflexion and plantarflexion of the foot.
- Talocalcaneal Joint (Subtalar Joint): Located between the talus and calcaneus, this joint enables inversion and eversion of the foot.
- Talonavicular Joint: This joint connects the talus with the navicular bone, contributing to foot flexibility and movement.
- Calcaneocuboid Joint: Found between the calcaneus and cuboid bones, this joint aids in lateral foot movement and stability.
- Navicularcuboid Joint: The navicular and cuboid bones articulate with each other.
Here's a table summarizing the joints of the tarsals:
| Joint Name | Bones Involved | Function |
|---|---|---|
| Talocrural Joint | Talus, Tibia, Fibula | Ankle flexion and extension |
| Talocalcaneal Joint | Talus, Calcaneus | Inversion and eversion of the foot |
| Talonavicular Joint | Talus, Navicular | Foot flexibility and movement |
| Calcaneocuboid Joint | Calcaneus, Cuboid | Lateral foot movement and stability |
| Navicularcuboid Joint | Navicular, Cuboid | Connects the navicular and cuboid bones |
