[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 ...
Alternatively, the term may have been influenced by the Greek τροχαντήρ (trochantḗr), which referred to the protrusions on the stern of triremes that served as attachment points for ropes and sails. In a similar manner, the anatomical trochanters are prominent bony projections that serve as key attachment sites for muscles. Later ...
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.
The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word malleolus ( / m ə ˈ l iː ə l ə s , m æ -/ [ 1 ] [ 2 ] ), plural malleoli ( / m ə ˈ l iː ə ˌ l aɪ , m æ -/ ), comes from Latin and means "small hammer ".
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.
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 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 first points backwards in most species while the second, third and fourth digits point forwards. The fifth toe is lost completely except in some birds where it has become a spur. A number of birds have spurs on their feet or legs, usually formed from the lower portion of the tarsometatarsus bone.
