Definition of ossification
1a : the natural process of bone formation. b : the hardening (as of muscular tissue) into a bony substance. 2 : a mass or particle of ossified tissue. 3 : a tendency toward or state of being molded into a rigid, conventional, sterile, or unimaginative condition.
What is ossification in biology?
Ossification (or osteogenesis or bone mineralization..) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation.
What is ossification in anatomy?
bone formation, also called ossification, process by which new bone is produced.
What is ossification and its types?
Osteoblasts are bone-forming cells, osteocytes are mature bone cells and osteoclasts break down and reabsorb bone. There are two types of ossification: intramembranous and endochondral.
What is a cartilage?
Cartilage a strong and smooth substance made up of “chondrocytes,” or specialized cartilage cells, that produce a matrix of collagen, proteoglycans (a special type of protein) and other non-collagenous proteins. These materials help cartilage attract water and give it its shape and specific properties.
What is another name for ossification?
In this page you can discover 13 synonyms, antonyms, idiomatic expressions, and related words for ossification, like: fossilization, hardening, induration, bone formation, ostosis, osteoblast osteoclast, conformity, endochondral, osseous, calcification and resorption.
What is calcification and ossification?
Metastatic and dystrophic calcification, defined as deposition of calcium salts in normal and abnormal tissues, respectively, can manifest in the lungs. Pulmonary ossification refers to bone tissue formation (calcification in a collagen matrix), with or without marrow elements, in the lung parenchyma.
Where does ossification occur?
Primary ossification center forms in the diaphyseal region of the periosteum called the periosteal collar. Secondary ossification centers develop in the epiphyseal region after birth.
What are osteoclasts?
Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/ monocyte lineage that circulate in the blood after their formation in the bone marrow.
What is the difference between osteogenesis and ossification?
Ossification, or osteogenesis, is the process of bone formation by osteoblasts. Ossification is distinct from the process of calcification; whereas calcification takes place during the ossification of bones, it can also occur in other tissues.
What are ligaments?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
Which came first bones or muscle?
Good point – yes – if you interpret the question evolutionarily, then animals with muscle tissue arose before animals with muscle and bone. In a developmental sense then they differentiate simultaneously in a developing (vertebrate) embryo.
What are epiphyseal plates?
A growth plate, also called an epiphyseal plate, is a section of cartilage located at the ends of the long bones of children and teenagers. It is here that new bone develops to add length as the child grows.
Which hormone is responsible for ossification of bones?
PTH stimulates bone formation as well as resorption.
What is the Centre of bone?
Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.
What is a joint?
A joint is the part of the body where two or more bones meet to allow movement. Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.
What are 3 types of cartilage?
There are three types of cartilage:
Hyaline – most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone.Fibro- is found in invertebral discs, joint capsules, ligaments.Elastic – is found in the external ear, epiglottis and larynx.
Is skin a connective tissue?
Skin is made up of connective tissue that consists of cellular components and an extracellular matrix. The extracellular matrix contains two main types of macromolecules: polysaccharide glycosaminoglycans and collagens.
