6.3 Bone Structure Learning Objectives By the end of this section, you will be able to: Describe the microscopic and gross anatomical structures of bones Identify the gross anatomical features of a bone Describe the histology of bone tissue, including the function of bone cells and matrix Compare and contrast compact and spongy 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.

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. 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. Gross Anatomy of Bone The structure of a long bone allows for the best visualization of all of the parts of a bone ( [link] ). 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. 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.

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. The walls of the diaphysis are composed of dense and hard compact bone. Figure 6.3.1 6.3. 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. 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. 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.

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. A cross section of the bone shows compact bone and blood vessels in the bone marrow. Also shown are red blood cells, white blood cells, platelets, and a blood stem cell. Anatomy of the bone. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone.
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.

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. 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.
