How would you anatomically describe the location of the talus on the human body?
The talus is a very compact and hard bone making up a part of the ankle joint where the tibia (shin bone) and fibula meet the foot. It is found at the top of the foot and is one of seven tarsal bones.
What part of the body is the talus?
The talus is the bone that makes up the lower part of the ankle joint (the tibia and fibula make up the upper part). The ankle joint allows your foot to move up and down. The talus also sits above the heel bone (calcaneus).
What supports the head of the talus?
The contact force of the calcaneonavicular ligament against the talus was found to be much smaller than those of other talar articulations; however, its medially oriented direction must contribute to stabilization of the head of the talus against medial displacement.
What is attached to the talus?
Muscle and ligamentous attachments. No muscles are attached to the talus but many ligaments are attached to the bone, creating stability in the ankle, subtalar and calcaneonavicular joints. On the lateral side, the joint is held together by the posterior talofibular and anterior talofibular ligaments.
What are the anatomical structure of talus?
The talus has been described as having three main components: head, neck, and body. It is an irregular saddle-shaped bone. The talar body has a curved smooth trochlear surface also termed the talar dome, which is covered with hyaline cartilage and convex from front to back.
Where is the head of talus?
The talar head is the part that articulates with the navicular bone. On its inferior aspect, this is continuous with three articular facets that are separated by smooth ridges. There are anterior and middle facets which articulate with corresponding facets on the calcaneus.
What is the medial talus?
The medial, situated in front of the middle calcaneal facet, is convex, triangular, or semi-oval in shape, and rests on the plantar calcaneonavicular ligament; the lateral, named the anterior calcaneal articular surface, is somewhat flattened, and articulates with the facet on the upper surface of the anterior part of …
What is Trochlea of talus?
The trochlea of talus is a convex articular surface for the proximal part of articulation with tibia and fibula (only with tibia in horses). The trochlea presents a sagittal groove that articulates with the sagittal ridge of cochlea of tibia.
What is tarsal and metatarsal?
metatarsal: A bone from the center of the foot that articulates with the tarsals and phalanges. tarsal: A bone forming part of the ankle or heel.
