Primary osteoporosis is mainly a disease of the elderly, the result of the cumulative impact of bone loss and deterioration of bone structure that occurs as people age (Seeman 2003). This form of osteoporosis is sometimes referred to as age-related osteoporosis.

What bone disorders result from loss of calcium and phosphorus?

Rickets is a preventable bone disease that affects infants and young children and causes soft and weakened bones. Rickets is caused by a lack of vitamin D, calcium or phosphorus.

What bone Do you have the greatest number of in your body?

Coming out on top are your hands and feet. Each hand has 27 bones, and each foot has 26, which means that together the body’s two hands and two feet have 106 bones. That is, the hands and feet contain more than half of the bones in your entire body.

Which of the following bones would be likely to contain red marrow?

Adults have on average about 2.6kg (5.7lbs) of bone marrow, with about half of it being red. Red marrow is found mainly in the flat bones such as hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous (“spongy”) material at the proximal ends of the long bones femur and humerus.

What skeletal structure is located in the skull *?

The neurocranium consists of two temporal bones situated to the base and side of the skull, and two parietal bones that make up the roof of the skull. A single occipital bone forms the base of the skull, and the frontal bone forms the forehead.

Which is a condition that result from the loss of calcium in the bones?

Osteoporosis is more likely to occur in people who have: Low calcium intake. A lifelong lack of calcium plays a role in the development of osteoporosis. Low calcium intake contributes to diminished bone density, early bone loss and an increased risk of fractures.

What are bone disorders?

metabolic bone disease, any of several diseases that cause various abnormalities or deformities of bone. Examples of metabolic bone diseases include osteoporosis, rickets, osteomalacia, osteogenesis imperfecta, marble bone disease (osteopetrosis), Paget disease of bone, and fibrous dysplasia.

What bone disorder results from a loss of bone density that is frequently seen with aging?

Overview. Osteoporosis, literally “porous bone,” is a disease that thins the framework inside bones so much that even a minor fall or bump against a car door or piece of furniture may cause a fracture. A break can happen at any spot on your skeleton, but fractures of the wrist, hip and spine are among the most common.

What is the most commonly broken bone?

The collarbone, otherwise known as the clavicle, is the most commonly broken bone, thanks in large part to where it’s positioned. Located between the shoulder blade and upper ribcage, it attaches the arm to the rest of the body.

Which bones contain bone marrow?

In adults, active marrow is found inside the spine, hip and shoulder bones, ribs, breastbone, and skull. However, bone marrow found in the spine and hip has the richest source of bone marrow cells. Bone marrow is contained within bones.

What bones do not contain red bone marrow?

Thereafter, fat tissue gradually replaces the red marrow, which in adults is found only in the vertebrae, hips, breastbone, ribs, and skull and at the ends of the long bones of the arm and leg; other cancellous, or spongy, bones and the central cavities of the long bones are filled with yellow marrow.

What is red bone marrow and yellow bone marrow?

There are two types of bone marrow: red and yellow. Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow bone marrow is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells.

What is appendicular skeletal system?

The appendicular skeleton is one of two major bone groups in the body, the other being the axial skeleton. The appendicular skeleton is comprised of the upper and lower extremities, which include the shoulder girdle and pelvis.

What are the cranial bones of the skull?

There are eight cranial bones, each with a unique shape:

• Frontal bone. This is the flat bone that makes up your forehead.
• Parietal bones. This a pair of flat bones located on either side of your head, behind the frontal bone.
• Temporal bones.
• Occipital bone.
• Sphenoid bone.
• Ethmoid bone.

What are the 3 bone groups of the skull?

It supports the structures of the face and forms a cavity for the brain. Like the skulls of other vertebrates, it protects the brain from injury. The skull consists of three parts, of different embryological origin— the neurocranium, the sutures, and the facial skeleton (also called the membraneous viscerocranium).
