It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including mesenchymal stem cells , which give rise to bone and fat cells, as well as hematopoietic stem cells which give rise to a variety of ...
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
Many bones in the body contain an epiphysis, a region critical for growth and articulation. The humerus, for example, is situated between the shoulder and elbow and contributes significantly to upper limb movement. Below the elbow are the radius and ulna, two bones that run parallel to each other.
Linear growth takes place in the epiphyseal growth plates (EGP) of long bones. [23] In the growth plate, chondrocytes proliferate, hypertrophy and secrete cartilage extracellular matrix. New cartilage is subsequently remodeled into bone tissue, causing bones to grow longer. [24]
Epiphysiodesis is a pediatric orthopedic surgery procedure that aims at altering or stopping the bone growth naturally occurring through the growth plate also known as the physeal plate. There are two types of epiphysiodesis: temporary hemiepiphysiodesis and permanent epiphysiodesis.
Plato explains how we are always many steps away from the idea or Form. The idea of a perfect circle can have us defining, speaking, writing, and drawing about particular circles that are always steps away from the actual being. The perfect circle, partly represented by a curved line, and a precise definition, cannot be drawn.
According to Max Heindel's Rosicrucian writings, [9] the etheric body, composed of four ethers, is called the "Vital Body" since the ether is the way of ingress for vital force from the Sun and the field of agencies in nature which promote such vital activities as assimilation, growth, and propagation. It is an exact counterpart of our physical ...
Plato was the first known person in the history of western philosophy to believe that the soul was both the source of life and the mind. [4] In Plato's dialogues, we find the soul playing many disparate roles.
