Rotation is the movement around a longitudinal axis.
What else can I help you with?
The continued erosion and replacement of bone tissue is called?
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.
What are the steps in bone deposition?
§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 :)
In bone the calcium phosphate forms crystals of?
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.
What is the main type of nutrient found in calcium?
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.
Is lead or bone more dense?
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.
What is a longitudinal axis for a bone?
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.
What does osteon compact bone tissue are aligned along?
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.
Does volkmass's canal carry blood vessels along the long axis of a bone?
yes
Is A radius a axial bone?
No, the radius is not classified as an axial bone; it is considered a long bone of the appendicular skeleton. The axial skeleton includes bones such as the skull, vertebrae, and rib cage, which support the central axis of the body. The radius, along with the ulna, is part of the forearm and plays a role in movement and stability of the arm.
What type of bone is the axis?
irregular bone
How many axis Pivot joints permit movement around only?
Pivot joints permit movement around only one axis. They allow for rotational movement where one bone rotates around another, such as in the neck (between the first and second cervical vertebrae) or the forearm (between the radius and ulna). This single-axis movement is essential for functions like turning the head or twisting the wrist.
Where are the atlas and axis bones found?
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.
What is atypical about the atlas bone?
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.
Bone that has the odontoid process?
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.
Does the axis form a joint with the hip bone?
No, the axis is located in the neck.
A bone fracture perpendicular to the bone's axis is called what?
transverse fracture
Tendons and ligaments must withstand tension along the axis of their fibers These structures are composed of?
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.
