Surrounding the external surface of all bones is a layer of connective tissue termed the periosteum. In addition, lining the marrow cavity of long bones is another, considerably thinner layer of connective tissue, the endosteum. The periosteum is divided into two layers: an outer fibrous layer and an inner osteogenic layer.

Gross Anatomy of Bone Figure 1. Anatomy of a Long Bone. A typical long bone shows the gross anatomical characteristics of bone. The structure of a long bone allows for the best visualization of all of the parts of a bone (Figure 1). A long bone has two parts: the diaphysis and the epiphysis.

Your brain is another organ that needs a lot of protection. The thick bone layer of your skull protects your brain. For this purpose, being "thick-headed" is a very good thing. Movement: Many of your bones fit together like the pieces of a puzzle. Each bone has a very specific shape which often matches up with neighboring bones.

Gross Anatomy of Bone The structure of a long bone allows for the best visualization of all of the parts of a bone ( Figure 6.7 ). A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone.

The walls of the diaphysis are composed of dense and hard compact bone. Figure 6.4.1 6.4. 1: \ Anatomy of a Long Bone A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.

Within a cortical bone shaft, shown in cross-section (Panel A) are osteons surrounded by interstitial bone and many osteocytic lacunae distributed around the central haversian canal (Panel B.

If you cut a cross-section through a bone, you would first come across a thin layer of dense connective tissue. This is known as the Periosteum. It consists of two layers; an outer 'fibrous layer' containing mainly fibroblasts, and an inner 'cambium layer' containing progenitor cells.

More importantly, the cross sections were "easier to read" and they "better define the outlines and limits to better understand the MRI". Stated more succinctly, cross-sections are essential. Vertebral body of L3 (MRI image) So far, it appears that cross-sections tick the boxes of preference and understanding.

Bone tissue is a mineralized tissue of two types: compact bone (cortical) and spongy bone (trabecular or cancellous). Above: A cross section of bone tissue shows the outer layers are composed of compact bone and the inner layers are composed of spongy bone.

1/7 Synonyms: Dorsal thalamus, Thalamencephalon , show more. Cross-sections are two-dimensional, axial views of gross anatomical structures seen in transverse planes. They are obtained by taking imaginary slices perpendicular to the main axis of organs, vessels, nerves, bones, soft tissue, or even the entire human body.

There are three distinct types of fibula shapes when viewed as a cross-section along the shaft: triangular, quadrilateral, and irregular. Each fibula can contain more than one type of cross-section shape, and the combinations differ between males and females. The fibula is the most slender long bone in the body as a ratio of width to length.

In a cross-section, the fibers of lamellar bone can be seen to run in opposite directions in alternating layers, much like in plywood, assisting in the bone's ability to resist torsion forces. When the same lamellar bone is loosely arranged, it is referred to as trabecular bone. Trabecular bone gets its name because of the spongy pattern it.

INTRODUCTION O STEOPOROSIS IS defined by abnormalities in both the amount of bone and the architectural arrangement of bone tissue, leading to decreased skeletal strength and increased fragility and fracture risk. 1 The role of low bone density in fracture risk in various skeletal regions is well established.
