Cortical bone is covered by a periosteum on its outer surface, and an endosteum on its inner surface. The endosteum is the boundary between the cortical bone and the cancellous bone.
Cancellous bone, also called trabecular or spongy bone,  is the internal tissue of the skeletal bone and is an open cell porous network. Cancellous bone has a higher surface-area-to-volume ratio than cortical bone and it is less dense.
This makes it weaker and more flexible. The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions.
Cancellous bone is typically found at the ends of long bones, near joints and in the interior of vertebrae. Cancellous bone is highly vascular and often contains red bone marrow where hematopoiesis , the production of blood cells, occurs.
The primary anatomical and functional unit of cancellous bone is the trabecula. The trabeculae are aligned towards the mechanical load distribution that a bone experiences within long bones such as the femur.
As far as short bones are concerned, trabecular alignment has been studied in the vertebral pedicle. Within these spaces are bone marrow and hematopoietic stem cells that give rise to platelets , red blood cells and white blood cells.
The words cancellous and trabecular refer to the tiny lattice-shaped units trabeculae that form the tissue. Bone marrow , also known as myeloid tissue in red bone marrow, can be found in almost any bone that holds cancellous tissue.
In adults, red marrow is mostly found in the bone marrow of the femur, the ribs, the vertebrae and pelvic bones. Bone is a metabolically active tissue composed of several types of cells.
These cells include osteoblasts , which are involved in the creation and mineralization of bone tissue, osteocytes , and osteoclasts , which are involved in the reabsorption of bone tissue.
Osteoblasts and osteocytes are derived from osteoprogenitor cells, but osteoclasts are derived from the same cells that differentiate to form macrophages and monocytes.
These cells give rise to other cells, including white blood cells , red blood cells , and platelets. Osteoblasts are mononucleate bone-forming cells.
They are located on the surface of osteon seams and make a protein mixture known as osteoid , which mineralizes to become bone.
Osteoid is primarily composed of Type I collagen. Osteoblasts also manufacture hormones , such as prostaglandins , to act on the bone itself.
The osteoblast creates and repairs new bone by actually building around itself. First, the osteoblast puts up collagen fibers.
These collagen fibers are used as a framework for the osteoblasts' work. The osteoblast then deposits calcium phosphate which is hardened by hydroxide and bicarbonate ions.
The brand-new bone created by the osteoblast is called osteoid. When the osteoblast becomes trapped, it becomes known as an osteocyte. Osteocytes are mostly inactive osteoblasts.
Osteocytes have many processes that reach out to meet osteoblasts and other osteocytes probably for the purposes of communication. Osteoclasts are very large multinucleate cells that are responsible for the breakdown of bones by the process of bone resorption.
New bone is then formed by the osteoblasts. Bone is constantly remodelled by the resorption of osteoclasts and created by osteoblasts.
These lacunae are the result of surrounding bone tissue that has been reabsorbed. Upon arrival, active enzymes, such as tartrate-resistant acid phosphatase , are secreted against the mineral substrate.
Bones consist of living cells embedded in a mineralized organic matrix. This matrix consists of organic components, mainly type I collagen —"organic" referring to materials produced as a result of the human body—and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.
These effects are synergistic. The inorganic composition of bone bone mineral is primarily formed from salts of calcium and phosphate , the major salt being hydroxyapatite Ca 10 PO 4 6 OH 2.
Collagen consists of strands of repeating units, which give bone tensile strength, and are arranged in an overlapping fashion that prevents shear stress.
The function of ground substance is not fully known. Woven bone is produced when osteoblasts produce osteoid rapidly, which occurs initially in all fetal bones, but is later replaced by more resilient lamellar bone.
In adults woven bone is created after fractures or in Paget's disease. Woven bone is weaker, with a smaller number of randomly oriented collagen fibers, but forms quickly; it is for this appearance of the fibrous matrix that the bone is termed woven.
It is soon replaced by lamellar bone, which is highly organized in concentric sheets with a much lower proportion of osteocytes to surrounding tissue.
Lamellar bone, which makes its first appearance in humans in the fetus during the third trimester,  is stronger and filled with many collagen fibers parallel to other fibers in the same layer these parallel columns are called osteons.
In cross-section , the fibers run in opposite directions in alternating layers, much like in plywood , assisting in the bone's ability to resist torsion forces.
After a fracture, woven bone forms initially and is gradually replaced by lamellar bone during a process known as "bony substitution.
Lamellar bone also requires a relatively flat surface to lay the collagen fibers in parallel or concentric layers. The extracellular matrix of bone is laid down by osteoblasts , which secrete both collagen and ground substance.
These synthesise collagen within the cell, and then secrete collagen fibrils. The collagen fibers rapidly polymerise to form collagen strands. At this stage they are not yet mineralised, and are called "osteoid".
Around the strands calcium and phosphate precipitate on the surface of these strands, within days to weeks becoming crystals of hydroxyapatite.
In order to mineralise the bone, the osteoblasts secrete vesicles containing alkaline phosphatase. This cleaves the phosphate groups and acts as the foci for calcium and phosphate deposition.
The vesicles then rupture and act as a centre for crystals to grow on. More particularly, bone mineral is formed from globular and plate structures.
There are five types of bones in the human body: long, short, flat, irregular, and sesamoid. In the study of anatomy , anatomists use a number of anatomical terms to describe the appearance, shape and function of bones.
Other anatomical terms are also used to describe the location of bones. Like other anatomical terms, many of these derive from Latin and Greek. Some anatomists still use Latin to refer to bones.
The term "osseous", and the prefix "osteo-", referring to things related to bone, are still used commonly today.
Some examples of terms used to describe bones include the term "foramen" to describe a hole through which something passes, and a "canal" or "meatus" to describe a tunnel-like structure.
A protrusion from a bone can be called a number of terms, including a "condyle", "crest", "spine", "eminence", "tubercle" or "tuberosity", depending on the protrusion's shape and location.
In general, long bones are said to have a "head", "neck", and "body". When two bones join together, they are said to "articulate". If the two bones have a fibrous connection and are relatively immobile, then the joint is called a "suture".
The formation of bone is called ossification. During the fetal stage of development this occurs by two processes: intramembranous ossification and endochondral ossification.
Intramembranous ossification mainly occurs during formation of the flat bones of the skull but also the mandible, maxilla, and clavicles; the bone is formed from connective tissue such as mesenchyme tissue rather than from cartilage.
Its function is to transmit sound vibrations from the eardrum to the incus. The malleus is only found in mammals. The incus is an anvil-shaped bone that connects the malleus to the stapes.
Its function is to transmit sound vibrations from the malleus to the stapes. The oval window is nothing but an opening to the inner ear, and it is covered with a membrane.
The function of the stapes is to transmit sound vibrations from the incus to the labyrinth of the inner ear. It is the smallest bone in the human body.
The shoulder is made of two bones that together allow the attachment of the arm to the body. The bones of the shoulder are as given below.
The scapula is a flat, triangular bone that forms the posterior part of the shoulder girdle. It connects the humerus upper arm with the clavicle.
It is commonly referred to as the shoulder blade. There are two such bones, one on each side of the shoulder.
It is commonly called the collarbone, and is a pair of small long bones that join the scapula to the sternum.
Put in simple words, it is the bone that attaches the arm to the body. An interesting fact about the clavicle is that it is the only long bone that lies horizontally.
The thorax is the part of the body between the neck and the abdomen. It is the portion below the neck that encloses the heart and the lungs.
This is a long T-shaped bone. It lies in the central portion of the rib cage, and is attached to the ribs via cartilage.
Together with the ribs, it forms the anterior part of the rib cage. It consists of three parts, and the topmost part is the manubrium, to which the clavicle is attached.
This is followed by the body to which the ribs are attached , and the xyphoid process. There are 12 pairs of ribs in all. The first seven pairs are directly attached to the sternum through cartilage.
The next three are attached to the sternum through a common cartilaginous extension. The last two pairs are known as the floating ribs because although they start from the thoracic vertebrae, they do not attach to the sternum.
The vertebral column, or the spinal column, is made up of 24 small bones, each of which is known as a vertebra.
In addition to the vertebrae, there are two other bones that form a part of the vertebral column: the sacrum and the coccyx.
The vertebrae give the vertebral column its flexibility due to which we can bend forwards and sideways. The various vertebrae are grouped as given below.
Cervical vertebrae 7 Thoracic vertebrae 12 Lumbar vertebrae 5 Sacrum 1 Coccyx 1. The cervical vertebrae are the first 7 vertebrae that are also the smallest of the true vertebrae.
They are different from those in the thoracic and lumbar regions for the fact that they have a hole or foramen in each transverse process for the vertebral artery to pass through.
The skull is supported by the first cervical vertebra, which is known as the atlas. After menopause, bone loss in women greatly exceeds that in men.
However, by age 65, women and men tend to lose bone tissue at the same rate. Although men do not undergo the equivalent of menopause, production of the male hormone testosterone may decrease, and this can lead to increased bone loss and a greater risk of developing osteoporosis.
Osteoporosis is preventable for many people. Prevention is important because although there are treatments for osteoporosis, a cure has not yet been found.
A comprehensive program that can help prevent osteoporosis includes:. Would you like to order publications on bone disorders to be mailed to you?
