The band of cartilage between the primary and secondary ossification centers is called the epiphyseal plate or growth plate. It is responsible for longitudinal bone growth in children and adolescents.
The primary ossification center is located in endochondral bones (the bones that form as a fetus is growing in the womb). It is in the shaft part of the bone (diaphysis), or the long, skinny part of it. Growth takes place in the epiphysial center of ossification. This primary ossification center is the key location for bone formation.
Primary centers of ossification first appear in the diaphysis of long bones during embryonic development, around the 8th week of gestation. This is where bone tissue begins to replace cartilage through endochondral ossification.
A primary cell cannot be recharged whereas a secondary cell can be recharged. In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is reversible. ... A primary cell is light and less expensive whereas a secondary cell is heavy and expensive.
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
Secondary ossification centers appear in the epiphyses.

The femur is formed through the endochondral ossification process. This is where bone replaces the cartilage. There are six steps in this type of ossification and they are as follows; one the development of cartilage model, two the growth of the cartilage model, three the development of the primary ossification center, four the development of the medullary cavity, five the development of the secondary ossification centers, and six the formation of articular cartilage and the epiphyseal plate.
Ossification of metacarpals occurs primarily through endochondral ossification, where a cartilage model is gradually replaced by bone. Initially, mesenchymal cells differentiate into chondrocytes, forming a cartilage template. As development progresses, blood vessels invade the cartilage, leading to the formation of a primary ossification center where bone tissue begins to replace the cartilage. This process continues until the metacarpals are fully formed and mature, with secondary ossification centers appearing at the ends to allow for growth.
what is the similarities between primary and secondary data
what are the diffrence between primary reserve and secondary reserve?
Hotels and restaurants are examples of primary providers in the hospitality industry. Secondary providers include conference centers and nightclubs.
Yes, primary nodules don't have germinal centers(active B cells) while secondary nodules do.
