Quick Answer: What Muscles Insert On The Calcaneus?

Function. Three muscles insert on the calcaneus: the gastrocnemius, soleus, and plantaris. These muscles are part of the posterior compartment of the leg and aid in walking, running and jumping.

What muscle inserts into the posterior calcaneus?

The calcaneus is the largest bone in the foot. It projects posterior to the tibia and fibula and acts as a short lever for the calf muscles ( gastrocnemius and soleus ) which insert onto its posterior surface via the Achilles tendon.

Which of the following tendons inserts onto the calcaneus?

The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon at the back of the lower leg, and is the thickest in the human body. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone.

What muscle inserts at the heel?

The gastrocnemius calf muscle is the most superficial of the calf muscles. It inserts onto the heel bone via the Achilles tendon. The gastrocnemius muscle flexes the foot at the ankle joint — that is it acts to point the foot downwards by bending it at the ankle joint, such as when you stand on your toes.

What is attached to calcaneus?

The posterior surface of the calcaneus has a circular convex structure with three distinct facets. The middle facet serves as the attachment site for the calcaneal tendon (Achilles tendon), while the superior facet is separated from the calcaneal tendon by the retrocalcaneal bursa.

Which muscle attaches to the femur and calcaneus?

Gastrocnemius: The gastrocnemius, a two-headed muscle, is the most superficial of the muscles in the posterior compartment. Attachments: Both heads originate from the femur. The fibers converge to form the calcaneal tendon which attaches to the heel.

Does the Achilles tendon attach to the calcaneus?

Overview and anatomy The Achilles tendon is a thick tendon located in the back of the leg. It connects the gastrocnemius and soleus muscles in the calf to an insertion point at the calcaneus (heel bone). It is the strongest tendon in the body and allows people to push off while walking, running and jumping.

Which muscle inserts to the calcaneus via the Achilles calcaneal tendon?

Gastrocnemius muscle originates from the femoral condyles and attaches to the posterior calcaneus via Achilles tendon. It is the prime plantar flexor of the ankle joint.

Where does the calcaneal tendon insert?

Achilles tendon, also called calcaneal tendon, strong tendon at the back of the heel that connects the calf muscles to the heel. The tendon is formed from the gastrocnemius and soleus muscles (the calf muscles) and is inserted into the heel bone.

What is the soleus muscle?

Located in superficial posterior compartment of the leg Soleus is a powerfull lower limb muscle which along with gastronemius and plantaris forms the calf muscle or triceps surae. It runs from back of knee to the ankle and is multipennate.

What muscle is the Achilles tendon?

The Achilles tendon is the strongest and largest tendon in the body. It is the conjoined tendon of the gastrocnemius and the soleus muscles, and may have a small contribution from the plantaris.

What are the four hamstring muscles?

The semitendinosus, semimembranosus, and biceps femoris muscles comprise the hamstring muscle group.

What is the muscle behind the ankle called?

The large tendon (Achilles tendon) of the calf muscle passes behind the ankle and attaches at the back of the heel. A large tendon of the leg muscle (posterior tibial tendon) passes behind the medial malleolus.

Which muscle inserts into the navicular bone?

The only muscle attachment on the navicular is the tendon of the tibialis posterior. This a muscle located within the deep compartment of the posterior aspect of the tibia and the tendon extends inferiorly around the medial malleolus to insert on the navicular tuberosity.

What ligaments are attached to the calcaneus?

Cervical ligament. Talocalcaneal interosseous ligament, Lateral, intermediate, and medial roots of the inferior extensor retinaculum. Bifurcate ligament.

What inserts on the Sustentaculum Tali?

Several ligamentous structures attach to the sustentaculum tali:

  • plantar calcaneonavicular ligament (anterior surface)
  • deltoid ligament (medial surface)
  • medial talocalcaneal ligament.
