A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. These bones form in tendons (the sheaths of tissue that connect bones to muscles) where a great deal of pressure is generated in a joint. The sesamoid bones protect tendons by helping them overcome compressive forces.
Anatomical landmarks. On the trunk of the body, the chest is referred to as the thoracic area. The shoulder in general is the acromial, while the curve of the ...
Some paleoanthropologists distinguish between frontal torus and supraorbital ridge. [2] In anatomy, a torus is a projecting shelf of bone that unlike a ridge is rectilinear, unbroken and goes through glabella. [3] Some fossil hominins, in this use of the word, have the frontal torus, [4] but almost all modern humans only have the ridge. [5]
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
It is an important surface landmark for various surgical approaches, such as treatment of hernia. [7] The severity of symptoms of damage to the iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine. [6] Bone may be harvested from the nearby iliac crest for use elsewhere in the body. [5]
The linea aspera is a prominent longitudinal ridge or crest, on the middle third of the bone, presenting a medial and a lateral lip, and a narrow rough, intermediate line. It is an important insertion point for the adductors and the lateral and medial intermuscular septa that divides the thigh into three compartments. The tension generated by ...
The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when the foot strikes the ground. [1] The two ligaments, the patella, and the tibial tuberosity are all superficial, easily palpable structures. [2]
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
