Skeletal System

Bone thickens as compact bone is deposited on the outside, just beneath the periosteum. As this compact bone forms on the surface, osteoclasts erode other bone tissue on the inside. The resulting space becomes the medullary cavity of the diaphysis, which later fills with marrow.

Bones often don't hurt at first because your body shuts the pain out in the shock of it all. After while a small bone would hurt the least because there are fewer nerves damaged. Perhaps the small finger in the hand you use least or the toes.

A bone marrow match is when a person's human leukocyte antigen (HLA) tissue type matches that of a patient in need of a bone marrow transplant. This matching is crucial to reduce the likelihood of rejection and improve the success of the transplant. Finding a compatible donor is essential for the patient's body to accept the new bone marrow and start producing healthy blood cells.

Cartilage and compact bone are both types of connective tissue found in the body. They both provide structural support and protection to various body parts. Additionally, both cartilage and compact bone contain cells embedded in a matrix of proteins and minerals.

It is unlikely that laying on your wrist all night would directly cause a broken wrist. However, prolonged pressure or awkward positioning could lead to discomfort or nerve compression in the wrist, but it typically would not result in a fracture without additional force or trauma.

The frontal bone forms the forehead and the upper part of the eye sockets, protecting the brain and supporting the structures of the face. It also provides attachment sites for various muscles that control facial expressions and eye movements. Additionally, the frontal bone plays a role in determining the shape of the skull.

The maturation of noncalcified bone matrix typically takes about 6-8 weeks. During this process, osteoblasts secrete collagen fibers which gradually mineralize into hydroxyapatite crystals, leading to the formation of mature bone tissue.

Bone marrow is part of the body's skeletal and lymphatic organ systems. It produces lymphocytes vital to the immune system.

The tailbone, or coccyx, is made up of 3 to 5 fused vertebrae.

The mandible (lower jaw bone) is the essential bone involved in the process of eating. It is responsible for the movement of the jaw during chewing and helps to break down food for digestion.

When osteoblasts begin to differentiate within a connective tissue, the process is called osteogenesis or ossification. This process involves the formation of new bone tissue through the secretion of extracellular matrix components by osteoblasts.

to protect interior organs

Periosteum is the hard strong layer of bone

The rib cage offers better protection than the skull because it surrounds vital organs like the heart and lungs. The skull primarily protects the brain, whereas the rib cage provides a larger area of coverage for crucial organs.

A fetal skull has six fontanels: two anterior (sagittal and frontal) and four posterior (two squamous and two mastoid). These membranous gaps eventually close as the skull bones fuse together during infancy.

The odontoid process, also known as the dens, is the bone feature of the second cervical vertebrae that articulates with the first cervical vertebrae. This connection forms the atlantoaxial joint, which allows for rotation of the head.

It is not recommended to use a hot tub with broken ribs as the heat can worsen inflammation and pain in the affected area. It's best to consult with a doctor for proper guidance on managing broken ribs.

The primary mineral found in bone matrix is hydroxyapatite, a crystalline form of calcium phosphate. It gives bone its strength and rigidity by providing a framework for bone structure.

"Arrow to the knee" is a reference to a line from the video game "The Elder Scrolls V: Skyrim," where non-playable characters mention being adventurers who took an arrow to the knee, signifying they are no longer able to adventure due to injury. The phrase became a popular internet meme and is often used humorously to signify someone giving up on a particular goal or dream.

The process that occurs when pore spaces in bone or wood are filled with silica is called silicification. During this process, silica-rich fluids permeate the material, replacing the organic matter and filling the pore spaces, which leads to the preservation of the original structure.

Straightening out a limb involves extending it so that it is in a linear or straight position, typically increasing the angle between the limb and the joint. This movement is controlled by the muscles and tendons surrounding the joint.

In bone, there are osteoblasts (cells which build bone) and osteoclasts (cells which break down bone). In the bone marrow and spongy bone, there are hematopoietic cells (cells which make blood). Bone is a type of connective tissue that is made of specialized cells that all work together for a common function. Their cellular and extracellular matrix is what makes bone cells so unique.

hyaline cartilage is present in the end of long bones.

The vitamin that promotes healthy bones is: Calcium. It does not only help promote healthy bones, but strong teeth too. Food sources can be dairy products, dark green vegetables, and dried legumes. :D

In your skull there are 29 bones. The main ones that make up the forehead are the Frontal bone and the frontal sinus although the forehead is just referred to as the Frontal. The two bones that make up the skull are the Cranium and the Mandible although both of these contain other bones.
