The anterior border is rough, for the attachment of the anterior fibers of the deltoid ligament of the ankle-joint. The posterior border presents a broad groove, the malleolar sulcus, directed obliquely downward and medially, and occasionally double; this sulcus lodges the tendons of the tibialis posterior and flexor digitorum longus.
In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges and the carpal bones (wrist bones), which articulate with the forearm. The metacarpal bones are homologous to the metatarsal bones in the foot.
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The talus (/ ˈ t eɪ l ə s /; Latin for ankle [1] or ankle bone; [2] pl.: tali), talus bone, astragalus (/ ə ˈ s t r æ ɡ ə l ə s /), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3]
posterior talofibular ligament; The posterior talofibular ligament runs horizontally between the neck of the talus and the medial side of lateral malleolus calcaneofibular ligament; The calcaneofibular ligament is attached on the posteromedial side of lateral malleolus and descends posteroinferiorly below to a lateral side of the calcaneus.
The intermetacarpal joints are in the hand formed between the metacarpal bones. The bases of the second, third, fourth and fifth metacarpal bones articulate with one another by small surfaces covered with cartilage. The metacarpal bones are connected together by dorsal, palmar, and interosseous ligaments.
The talocrural joint is the only mortise and tenon joint in the human body, [9]: 1418 the term likening the skeletal structure to the woodworking joint of the same name. The bony architecture of the ankle consists of three bones: the tibia, the fibula, and the talus.
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, and includes histology (the study of the organization of tissues), and cytology (the study of ...
