Dec 21, 2022 · Medullary cavity, also known as the marrow cavity or the medulla, is a hollow space located within the long bones of the body, such as the humerus, femur, and tibia. It is filled with a soft, spongy tissue called bone marrow, which plays a vital role in the production of red and white blood cells.
Oct 30, 2023 · The medullary cavity (marrow cavity) is the hollow central space found within the shaft (diaphysis) of long bones. Its walls are formed by a thin layer of spongy bone, which is itself surrounded by a thick layer of compact bone comprising the diaphysis.

Section Review. Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.

Lining the inside of the bone adjacent to the medullary cavity is a layer of bone cells called the endosteum (endo- = “inside”; osteo- = “bone”). These bone cells (described later) cause the bone to grow, repair, and remodel throughout life.

The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard compact bone. Figure 1. Anatomy of a Long Bone.

Nov 15, 2016 · The zygomata are the origins for masticatory muscles, in particular the masseter muscles. The bones have interesting variations throughout mammalian and primate evolution that possibly reflect functional adaptations of the midfacial skeleton, and include both cortical and trabecular bone structures.
