A bone is a rigid organ [1] that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external ...
Lamellar armour is a type of body armour, made from small rectangular plates (scales or lamellae) of iron or steel, leather , bone, or bronze laced into horizontal rows. Lamellar armour was used over a wide range of time periods in Central Asia , Eastern Asia (especially in China , Japan , Korea , Mongolia , and Tibet ), Western Asia , and ...
Laminar armour. Roman lorica segmentata worn with manica. Laminar armour (from Latin: lamina – layer) is an armour made from horizontal overlapping rows or bands of, usually small, solid armour plates called lames, [1] as opposed to lamellar armour, which is made from individual armour scales laced together to form a solid-looking strip of ...
Bone healing. Bone healing of a fracture by forming a callus as shown by X-ray. Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or ...
The primary center of ossification is the area where bone growth occurs between the periosteum and the bone. Osteogenic cells that originate from the periosteum increase appositional growth and a bone collar is formed. The bone collar is eventually mineralized and lamellar bone is formed.
Lamellar structure. A schematic of a lamellar structure for a eutectic system. In materials science, lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. They are often observed in cases where a phase transition front moves quickly, leaving behind two solid products, as ...
Gross features. Bones are commonly described with the terms head, neck, shaft, body and base. The head of a bone usually refers to the distal end of the bone. The shaft refers to the elongated sections of long bone, and the neck the segment between the head and shaft (or body). The end of the long bone opposite to the head is known as the base.
Lamellae can also describe the layers of atoms in the crystal lattices of materials such as metals. In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. In chemical engineering, the term is used for devices such as filters and heat exchangers.
