The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia's anterior surface, distal to the medial condyle. It creates a bony prominence just below the patella, and can be easily located with the fingers.
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]
Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: a posterior, rough portion , for the insertion of the tendon of the biceps brachii .
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.
Definition Etymologic memory aid; apophysis: Any of various processes or protuberances on a bone. apo-+ physis, "outward from the growth part; outgrowth" diaphysis: The long, relatively straight main body of a long bone; region of primary ossification. Also known as the shaft. dia-+ physis, "between the growth parts" epiphysis
The deltoid tuberosity is a roughened surface on the lateral surface of the shaft of the humerus and acts as the site of insertion of deltoideus muscle. The posterorsuperior part of the shaft has a crest, beginning just below the surgical neck of the humerus and extends till the superior tip of the deltoid tuberosity.
The pubic tubercle is a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis bone.The inguinal ligament attaches to it. [1]
The parietal eminence (parietal boss, parietal tuber, parietal tuberosity) is a convex, smooth eminence on the external surface of the parietal bone of the skull. It is the site where intramembranous ossification of the parietal bone begins during embryological development .
