What is the common name for calcaneus?
The calcaneus, also known as the heel bone, is found at the back of the foot near the ankle, just below the talus, tibia, and fibula bones of the lower leg.
What connects to the calcaneus?
Three muscles join together to form the Achilles tendon and connect to the calcaneal tubercle. Additionally, six muscles originate from the calcaneal surface and disperse to the areas where they function.
What is a calcaneus in anatomy?
The calcaneus is a roughly rectangular prism-shaped bone located inferior to the talus and posterior to the midfoot. The long axis of the prism extends approximately along the mid-line of the foot. To understand the calcaneus structure, it is necessary to examine its six surfaces separately.
What is the bottom of your heel called?
The plantar fascia is the thick tissue on the bottom of the foot. It connects the heel bone to the toes and creates the arch of the foot. When this tissue becomes swollen or inflamed, it is called plantar fasciitis.
What is your heel bone called?
Overview. The calcaneus is the large bone at the heel of the foot. It is usually fractured after a fall from a great height or in a motor vehicle accident.
What is the calcaneus muscle?
The Achilles tendon is a tough band of fibrous tissue that connects the calf muscles to the heel bone (calcaneus). The Achilles tendon is also called the calcaneal tendon. The gastrocnemius and soleus muscles (calf muscles) unite into one band of tissue, which becomes the Achilles tendon at the low end of the calf.
What is the function of the tarsals?
In humans the tarsals, in combination with the metatarsal bones, form a longitudinal arch in the foot—a shape well adapted for carrying and transferring weight in bipedal locomotion. In the human ankle there are seven tarsal bones.
Is the calcaneus a joint?
The calcaneus is located in the hindfoot with the talus and is the largest bone of the foot. It is commonly referred to as the heel. It articulates with the talus superiorly and the cuboid anteriorly and shares a joint space with the talonavicular joint, appropriately called the talocalcaneonavicular joint.
