MICROANATOMY

Detailed explanation-1: -Tuberosity-A moderate prominence where muscles and connective tissues attach. Its function is similar to that of a trochanter. Examples include the tibial tuberosity, deltoid tuberosity, and ischial tuberosity. Tubercle-A small, rounded prominence where connective tissues attach.

Detailed explanation-2: -There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).

Detailed explanation-3: -The body of ischium is rough and broad with three bony surfaces, which include the medial (pelvic), lateral (femoral) and posterior surfaces.

Detailed explanation-4: -Ischial tuberosity-a bony process on the ramus of the ischium at the lower end of the lesser sciatic notch. Ischial spine-a bony prominence found on the ramus of the ischium between the greater and lesser sciatic notches.
