[14] Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another. An example is the foramen magnum in occipital bone. A canal is a long, tunnel-like foramen, usually a passage for notable nerves or blood vessels. An example is the ...
It forms a bony prominence behind and below the ear. [1] It has variable size and form (e.g. it is larger in the male than in the female). It is also filled with sinuses, or mastoid cells. The mastoid process serves for the attachment of the sternocleidomastoid, the posterior belly of the digastric muscle, splenius capitis, and longissimus capitis.
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of
Hyperextension of the wrist can lead to fracture of Lister's tubercle, as pressure is increased from the extensor pollicis longus tendon. [7] An "island-shaped" fracture can also expose the tendon to a rough edge and lead to tendon rupture (usually long after the initial fracture).
In the human skull, the zygomatic bone (from Ancient Greek: ζῠγόν, romanized: zugón, lit. 'yoke'), also called cheekbone or malar bone, is a paired irregular bone, situated at the upper and lateral part of the face and forming part of the lateral wall and floor of the orbit, of the temporal fossa and the infratemporal fossa.
Near the middle of the squamous part of occipital bone is the external occipital protuberance, the highest point of which is referred to as the inion. The inion is the most prominent projection of the protuberance which is located at the posterioinferior (rear lower) part of the human skull. The nuchal ligament and trapezius muscle attach to it.
In the skeleton of humans and other animals, a tubercle, tuberosity or apophysis is a protrusion or eminence that serves as an attachment for skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone. [1] A tuberosity is generally a larger tubercle.
The origin of Galen's term is unclear. Supposedly the sacrum was the part of an animal offered in sacrifice (since the sacrum is the seat of the organs of procreation). [24] Others attribute the adjective ἱερόν to the ancient belief that this specific bone would be indestructible. [22]
