Rotation is the movement around a longitudinal axis.
The continued erosion and replacement of bone tissue is called bone remodeling. This process is balanced by osteoclasts breaking down old bone and osteoblasts forming new bone. It is essential for maintaining bone health and strength.
Hydroxyapatite. This is a mineral that gives bone its strength and hardness. It consists of calcium and phosphate ions that combine to form crystals within the bone matrix.
§The initial stage in bone production is the secretion of collagen molecules and ground substance by osteoblasts. §The collagen monomers polymerize rapidly to form collagen fibers. §The resultant tissue becomes osteoid §As the osteoid is formed, some of the osteoblasts become entrapped in the osteoid and become quiescent osteocytes. §Within a few days after the osteoid is formed, calcium salts begin to precipitate on the surfaces of the collagen fibers. §The precipitates first appear at intervals along each collagen fiber, forming minute nidi that rapidly multiply and grow over a period of days and weeks into the finished product, hydroxyapatite crystals. hope thats good enough :)
There are no 'nutrients' in calcium. Calcium is a nutrient. It's essential to muscle movement and it composes most of the mass in bones.
Lead is denser than bone. Lead has a density of 11.34 g/cm³, while bone has a density ranging from 1.7 to 2.0 g/cm³ depending on its composition and density.
The longitudinal axis of a bone is an imaginary line that runs along the length of the bone from one end to the other. It helps to define the orientation and direction of forces acting on the bone, such as during movement or weight-bearing activities. Understanding the longitudinal axis is important in biomechanics and in the study of bone structure and function.
Osteons in compact bone tissue are aligned along the axis of stress to provide structural support and strength to the bone. This alignment helps to distribute mechanical forces and resist bending or twisting during movement.
yes
irregular bone
The atlas and axis bones are found in the neck region of the spine, known as the cervical spine. The atlas bone is the topmost cervical vertebra that holds up the skull, while the axis bone is located just below the atlas and allows for rotational movement of the head.
The atlas is the very top vertebra in your spine. The head or skull rests on it, and is allowed to move in many directions. The atlas sits upon the axis vertebra - between them, they allow much more rotational movement than do other vertebrae. Also, the actual brain stem extends down into the atlas/axis pair. The spinal cord begins at the bottom of the axis bone.
No, the axis is located in the neck.
This is also knows as the Dens.. It is located with the Atlas (c1) and the Axias (c2) it helps with the rotation of the head.
transverse fracture
Tendons are the elastic bands that connect muscle to bone, while ligaments are the bands that connect bone to bone. Both are made of connective tissue that is composed of collagen.
That cracking sound is the result of crepitus, which is the result of bone on bone movement or bone on ligament movement.
Rotation involves, Rotation of the head, neck and lower limb and circumduction, abduction is the angular movements: abduction, adduction and circumduction of the upper limb at the shoulder
