In osteology, the osteon or haversian system (/ h ə ˈ v ɜːr. ʒ ən /; named for Clopton Havers) is the fundamental functional unit of much compact bone. Osteons are roughly cylindrical structures that are typically between 0.25 mm and 0.35 mm in diameter . [ 1 ]
Skeletal System of Human Body Long bones are characterized by a shaft, the diaphysis, that is much longer than its width; and by an epiphysis, a rounded head at each end of the shaft. They are made up mostly of compact bone, with lesser amounts of marrow, located within the medullary cavity, and areas of spongy, cancellous bone at the ends of ...
A human skeleton (endoskeleton). Osteology (from Greek ὀστέον (ostéon) 'bones' and λόγος (logos) 'study') is the scientific study of bones, practised by osteologists.
Endochondral ossification is responsible for development of most bones including long and short bones, [4] the bones of the axial (ribs and vertebrae) and the appendicular skeleton (e.g. upper and lower limbs), [5] the bones of the skull base (including the ethmoid and sphenoid bones) [6] and the medial end of the clavicle.

In retail marketing, an endcap, end cap, Free Standing Display Unit (FSDU), or gen-end (general end shelving) is a display for a product placed at the end of an aisle. It is perceived to give a brand a competitive advantage. [1] It is often available for lease to a manufacturer in a retail environment.
Bone is broken down by osteoclasts, and rebuilt by osteoblasts, both of which communicate through cytokine (TGF-β, IGF) signalling.Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts.
Each corpuscle is associated with a myelinated axon; [3] these are some of the largest and fastest-conducting sensory axons arising from the skin. [8]Towards the center of the corpuscle, the axon loses its sheaths, ending as with a slight bulge at the center of the corpuscle.
Psychological Capital Questionnaire (PCQ): The original and validated form of the PCQ. It can be used as a self-assessment and a multi-rater assessment, meaning that the assessment considers the target individual's self-assessment alongside the assessments from others who rate the target individual's PsyCap.
