Which of the anatomical feature is the sustentaculum tali?
The sustentaculum tali is a horizontal shelf that arises from the anteromedial portion of the calcaneus. The superior surface is concave and articulates with the middle calcaneal surface of the talus. The inferior surface has a groove for the tendon of flexor hallucis longus.
What is the function of sustentaculum tali?
Anatomical Parts At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali, which gives attachment to a slip of the tendon of the Tibialis posterior.
What structure passes under the sustentaculum tali?
deltoid ligament (medial surface)
What muscle runs under sustentaculum tali?
flexor hallucis longus
The flexor hallucis longus is a muscle arising in the calf. Its tendon passes behind the medial malleolus of the ankle, and enters the sole on its medial side. It lies in the bony groove on the inferior surface of sustentaculum tali of the calcaneus as it enters the sole (see Fig.
Is the sustentaculum tali part of calcaneus?
The sustentaculum tali is part of the medial aspect of the calcaneus.
Where is the sustentaculum tali located?
calcaneus
The sustentaculum tali is a triangular projection found on the medial surface of the calcaneus, with its base facing posteriorly and apex (Fig 3a) anteriorly. The superior surface contains the middle calcaneal facet.
What is sustentaculum tali fracture?
Fractures of the sustentaculum tali are rare injuries that often occur in conjunction with ipsilateral foot and ankle injuries. Displaced sustentacular fractures can be safely approached from the medial aspect of the heel, retracting the neurovascular bundle distally.
What does Tali mean in anatomy?
(tā′lŭs) plural.tali [L., ankle] The ankle bone. It is an irregular, stubby cylinder and articulates with the tibia, fibula, calcaneus, and navicular bone. In front its head has a broad, rounded articular surface that meets the navicular bone.
Which bone of the foot or ankle has the sustentaculum tali as a component?
The middle facet lies on a medially projecting process of the calcaneus called the sustentaculum tali (see the image below). It articulates with the middle calcaneal facet on the under surface of the talus.
What does Sustentaculum mean?
Medical Definition of sustentaculum : a body part that supports or suspends another organ or part.
Is the sustentaculum tali a joint?
There are two joints under the talus (Fig. 6.76). Posteriorly the upper surface of the calcaneus articulates with the talus and anteriorly the head of the talus articulates with the sustentaculum tali of calcaneus, the navicular and the intervening spring ligament.
What is the role of Sertoli cell?
Sertoli cells are the somatic cells of the testis that are essential for testis formation and spermatogenesis. Sertoli cells facilitate the progression of germ cells to spermatozoa via direct contact and by controlling the environment milieu within the seminiferous tubules.
What is meaning of Sertoli cell?
Definition of Sertoli cell : one of the elongated striated cells lining the seminiferous tubules that support and apparently nourish the spermatids.
Where is Sertoli cells located?
Sertoli cells are present in the seminiferous tubules of the male gonads, the testes. They were first observed in 1865 by a young Italian physician Enrico Sertoli and named after him.
Which hormone is secreted by Sertoli cells?
peptide hormone inhibin B
Sertoli cells produce and secrete the peptide hormone inhibin B into the circulation as a response to FSH stimulation.
