  2. Talus bone - Wikipedia

    en.wikipedia.org/wiki/Talus_bone

    The talus is the second largest of the tarsal bones; [4] it is also one of the bones in the human body with the highest percentage of its surface area covered by articular cartilage. It is also unusual in that it has a retrograde blood supply, i.e. arterial blood enters the bone at the distal end.

  3. Tarsus (skeleton) - Wikipedia

    en.wikipedia.org/wiki/Tarsus_(skeleton)

    Together, the talus and calcaneus form the hindfoot. [1] The five irregular bones of the midfoot—the cuboid, navicular, and three cuneiform bones—form the arches of the foot which serves as a shock absorber. The midfoot is connected to the hind- and forefoot by muscles and the plantar fascia. [1]

  4. Arches of the foot - Wikipedia

    en.wikipedia.org/wiki/Arches_of_the_foot

    Its weakest part (i.e., the part most liable to yield from overpressure) is the joint between the talus and navicular, but this portion is braced by the plantar calcaneonavicular ligament a.k.a. spring ligament, which is elastic and is thus able to quickly restore the arch to its original condition when the disturbing force is removed.

  5. Calcaneus - Wikipedia

    en.wikipedia.org/wiki/Calcaneus

    Between these superior articulations and the equivalents on the talus is the tarsal sinus (a canal occupied by the interosseous talocalcaneal ligament). [ citation needed ] At the upper and forepart of the medial surface of the calcaneus, below the middle talar facet, there is a horizontal eminence, the talar shelf (also sustentaculum tali ). [ 2 ]

  6. Ankle - Wikipedia

    en.wikipedia.org/wiki/Ankle

    The muscle spindle gives feedback to the CNS system on the current length of the muscle it innervates and to any change in length that occurs. It was hypothesized that muscle spindle feedback from the ankle dorsiflexors played the most substantial role in proprioception relative to other muscular receptors that cross at the ankle joint.

  7. Superior tarsal muscle - Wikipedia

    en.wikipedia.org/wiki/Superior_tarsal_muscle

    The superior tarsal muscle receives its innervation from the sympathetic nervous system.Postganglionic sympathetic fibers originate in the superior cervical ganglion, and travel via the internal carotid plexus, where small branches communicate with the oculomotor nerve as it passes through the cavernous sinus. [1]

  8. Cuneiform bones - Wikipedia

    en.wikipedia.org/wiki/Cuneiform_bones

    It occupies the center of the front row of the tarsal bones, between the intermediate cuneiform medially, the cuboid laterally, the navicular posteriorly and the third metatarsal in front. The tibialis posterior inserts at the lateral cuneiform, while the flexor hallucis brevis originates from it.

  9. Navicular bone - Wikipedia

    en.wikipedia.org/wiki/Navicular_bone

    The navicular bone in humans is one of the tarsal bones, found in the foot. Its name derives from the human bone's resemblance to a small boat, caused by the strongly concave proximal articular surface. The term navicular bone or hand navicular bone was formerly used for the scaphoid bone, [1] one of the carpal bones of the wrist.
