Skeletal System

Collagen is the most important organic component of bone composition, making up around 90% of the organic matrix. Other important organic components include osteocalcin, osteonectin, and glycosaminoglycans. These components provide strength, flexibility, and structure to bones.

No not at present there are experiments at the moment going on in several country's where the aim is to regrow cartilage and bone in a controlled manner to repair joints but nothing has been introduced in that direction yet. one of the big problems wit arthritis is that the bone that is damaged as a result of missing cartilage tries to repair itself leading to ridges of bone forming where they do more harm then good.

there are two 'knee bones'. One on each leg. They are both called patellas. (singular: patella).

The joints between the phalanges are classified as hinge joints. These joints allow movement in one plane, primarily flexion and extension.

Collagen fibers in the periosteum, a dense layer of connective tissue covering bones, help anchor tendons and ligaments to bones. They also contribute to the strength and flexibility of bones by providing structural support and resisting tension and stretching forces.

Open reduction means there is an incision made and the bones are lined up visually and usually also using x-rays or fluorscopy. Closed reduction is done without an incision and with the aid of x-ray or fluoroscopy. Open reduction usually requires instrumentation such as wires, screws, or implants.

Bones in a joint move by the contraction and relaxation of muscles attached to them. The movement is facilitated by the friction-reducing synovial fluid in the joint. The type and range of movement depend on the specific joint and its structure.

Streptococcus bacteria can infect any part of the body, including the knees. Common symptoms of a streptococcal knee infection may include pain, redness, swelling, and difficulty moving the joint. If you suspect a streptococcal infection in your knee, it is important to seek medical attention for proper diagnosis and treatment.

The olfactory nerve tracts, responsible for the sense of smell, could be most easily damaged by a fracture of the cribriform plate of the ethmoid bone. This bone is located at the base of the skull and has small perforations for the olfactory nerve fibers to pass through, making it vulnerable to damage from trauma.

The radius bone helps stabilize the wrist joint by providing a foundation for the hand to move smoothly against the forearm. It supports the carpal bones and contributes to the range of motion in the wrist. The shape and position of the radius bone play a crucial role in maintaining proper wrist alignment and function.

Intramembranous ossification is the process by which osteoblasts lay down bone within a connective tissue membrane, leading to the formation of flat bones such as the skull and ribs.

Yes, fibrocartilage can be found at the connection of the ribs and sternum. This type of cartilage provides strength and support in this area due to its high collagen content and ability to withstand pressure and tension.

The process is called a knee jerk reflex. It is a simple reflex that occurs when the patellar tendon is tapped, resulting in the lower leg kicking forward involuntarily.

A combination of bones and cartilage form the skeletal system in the body, providing support, structure, and protection for internal organs. Bones are hard and rigid, while cartilage is smooth and flexible, helping joints move smoothly and acting as a cushion between bones.

The ulnar groove also known as the ulnar sulcus is a slight depression found at the inferior, posterior, medial side of the humerus bone. The ulnar nerve runs downwards in the ulnar groove to go to the ulna.

The bone found in the lower leg is called the fibula. It is one of the two bones in the lower leg, along with the tibia. The fibula is smaller and thinner than the tibia and mainly assists with providing stability and support to the lower leg.

Osteomalacia is a disease characterized by softening of the bones due to a lack of vitamin D, calcium, or phosphorus in the diet or issues with their absorption. This can lead to bone pain, fractures, and deformities. Treatment often involves vitamin D and mineral supplementation.

No, the diaphragm lies superior to the organs in the thoracic cavity. It is a dome-shaped muscle that separates the thoracic cavity from the abdominal cavity and plays a key role in the process of respiration.

The large soft spot at the junction of the parietal bones and the frontal bone in the infant cranium is called the anterior fontanelle. It allows for the growth and expansion of the skull during infancy.

Muscle spasms on the left side below the rib cage could be caused by muscle strain, dehydration, electrolyte imbalances, or underlying medical conditions such as costochondritis or intercostal muscle strain. It is best to consult with a healthcare provider for a proper diagnosis and treatment plan.

Nonspecific diffusely heterogeneous bone marrow appearance refers to abnormal imaging findings on a bone marrow MRI or CT scan where the marrow shows a mottled or uneven appearance without a specific underlying cause. This can be seen in various conditions such as infection, inflammation, or infiltrative diseases affecting the bone marrow. Further evaluation may be necessary to determine the underlying cause.

Cartilage is a tough, flexible connective tissue that is softer than bone. It provides structure and support to various parts of the body, such as the joints, ears, and nose. Cartilage also helps cushion and protect bones from rubbing against each other.

There are two bones in your arm, but if it's the longer one in your forearm then it's called the ulna.

Yes. The skull sits on the top vertebra of your spine, called the atlas. If there is a strong enough trauma to the head, the skull can be moved off, or dislocated, from the atlas. Unfortunately, with enough force this causes fatal damage to the spinal cord/brain. But if there is a smaller dislocation, it can be survived.

The hyoid bone in your neck is usually broken if a person is strangled.
