Skeletal System

Osteoporosis is a disease caused by the loss of bone calcium, leading to bones becoming weak and brittle, making them more prone to fractures. It is most commonly seen in postmenopausal women and the elderly. Regular weight-bearing exercise and sufficient dietary calcium and vitamin D intake can help prevent or manage osteoporosis.

Capillary refill refers to how quickly the color returns to the external capillary bed following pressure that has been applied to an area. A brisk capillary refill means that the color returned to the capillary bed rather quickly.

The tough fibrous sheath around the bone is called the periosteum. It is essential for bone growth, repair, and nutrition.

Long bone: the ends are called the epiphysis, the shaft is called the diaphysis. There is articular cartilage on either ends. The long bones distally and proximally have red marrow. There is yellow marrow in the diaphysis. The yellow marrow is mostly fat. On the surface of the bone is a periosteum which covers the endosteum. The center is called the medullary cavity.
The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone. It is connected to the bone shaft by the epiphyseal cartilage, or growth plate, which aids in the growth of bone length and is eventually replaced by bone.

The stapes bone in the middle ear contains an apex (which connects to the incus bone) and a base (which connects to the oval window of the inner ear).

Common disorders that may affect the bones of the hand include fractures, osteoarthritis, carpal tunnel syndrome, and trigger finger. These conditions can cause pain, stiffness, swelling, and limited range of motion in the hand. Proper diagnosis and treatment by a healthcare professional are important for managing these disorders effectively.

Yes, bone remodeling affects both compact and spongy bone tissues. It involves the removal of old bone by osteoclasts and the formation of new bone by osteoblasts, leading to changes in bone structure and density. The process helps maintain bone strength and repair microdamage.

Hydroxyapatite is a mineral compound that plays a crucial role in providing the hardness and stiffness to bones. It contributes to bone strength and density, making it an essential component for overall bone health and structure. Moreover, hydroxyapatite also serves as a reservoir for important minerals like calcium and phosphorus, which are essential for various biological processes in the body.

There are a number of conditions that can result in pain associated with the rib cage. The possible conditions range from less serious, but very uncomfortable, muscle spasms (intercostals, serratus ant. or post., iliocostalis, etc.) or inflamatory disorders (costochondritis) to more serious primary pulmonary pathologies. Your best option would be to make an appointment with an osteopathic or chiropractic physician who will be able to determine the appropriate course of action for your specific condition.

Yes, the calcaneus is considered part of the appendicular skeleton. It is the largest bone in the foot and is located in the hindfoot, contributing to the structure and support of the foot and ankle.

It is known as the iliac crest. It is located at the superior (upper) edge of the ilium. In females, the iliac crest is longer, and curves outward (laterally) more so than in males. This is part of the wider structure of the ilium in females, than in males, which accounts for wider hips as a norm.

Overactive bone marrow refers to a condition where the bone marrow produces an excessive number of blood cells. This can lead to conditions such as polycythemia vera, where there is an overproduction of red blood cells, or essential thrombocythemia, characterized by an excess of platelets. Treatment aims to regulate blood cell production to prevent complications such as blood clots or bleeding disorders.

1995 Merck put it out. It is said to re-build bone. It does NOT re-build bone. To explain it simply as possible; there are two types of bone cells that live in our bones that regulate the building and dissolving of our bones. Purpose; is when a bone is put under stress (carrying something heavy, jogging etc.) it stimulates the osteoblast to build bone or strengthen that area under stress. So it takes minerals out of our blood stream ( mainly calcium ) and deposits them in our bones, so strenghtening that area of bone. If there is not enough minerals in your blood stream to do this than the ostoeblasts can not do its job of re-building the bone. Or if you never put your bones under stress it doesn't signal these osteoclast to go to work, causing bones to weaken.

Our bones also has cells that dissolve bone. There is a purpose for them too. They help dissolve the old or dying bone cells. Also if our blood levels of calcium get too low they go to work dissolving bone so it can then be picked up by the blood stream and used where needed in the body. Every time you move a muscle and every heart beat (muscle) calcium is needed for the body to preform these functions. Our heart couldn't beat with out enough calcium in our blood. Fosamax and similar drugs KILL these osteoclasts. At first it seems to be working in building bone, because none is removed even the worthless dead cells. Dead bone cells have no strengh, they crumble under pressure. When the dead and dying cell begin to build up you end up with dead debre, being a perfect host to bacterium and other harmful things. Plus you loose strengh. Xrays APPEAR to us as if there is more bone. Well there is, dead bone.

Intramembranous ossification produces flat bones of the skull, face, and clavicles. This process involves the direct ossification of mesenchymal cells without a cartilage precursor.

Capillary transport mechanisms refer to the movement of fluids through capillaries by processes such as diffusion, filtration, and osmosis. These mechanisms help to transport nutrients, gases, and waste products to and from cells in the body. The exchange of substances across capillaries is essential for maintaining proper tissue function.

short bones are mostly spongey bones and help hold shape and keep structure strong, flat bones usually protect or help with movementeg. the skull, sternum and scapula, long bones are also sponget bones that hold the shape of the body so that joints can function and move and irrregular bones are the miscelanious type of bone that varies in function, each one is different, eg. mandable and vertebrae.

The collarbones are also known as clavicles. They are long, slender bones that run horizontally across the front of the chest, connecting the shoulder blades to the sternum.

No, not all Canadians have an extra bone in their hands. The presence of an extra bone in the hand, called the os centrale, is considered a normal anatomical variation that can be found in some individuals, regardless of their nationality.

No, bones are not considered internal organs. They are a part of the skeletal system and provide structural support, protect organs, and aid in movement. Internal organs are typically soft tissues located inside the body cavities.

The appendicular skeleton has more bones than the axial skeleton. The axial skeleton includes the skull, spine, and rib cage, which have a total of 80 bones. In contrast, the appendicular skeleton includes the bones of the limbs, shoulders, and hips, totaling 126 bones.

the upper legs of a frog have less power than the back legs and they are different in lenth.

The spine of the scapula is located on the posterior aspect of the scapula, dividing it into the supraspinous fossa and infraspinous fossa. It is a prominent ridge that runs horizontally across the bone and serves as an attachment site for muscles that move the arm and shoulder.

A knee can be dislocated as a result of a sudden impact and force directly on the knee. For example: a direct hit on the knee from a fall. It can be dislocated as a result of an awkward running position as well. Dislocations can also occur from medical problems associated with disease.
