intramembranous ossification

Intramembranous ossification forms the flat bones of skull, clavicle and mandible.

The steps in intramembranous ossification are:

The mesenchyme above the meninges undergoes intramembranous ossification forming the neurocranium.

This is called intramembranous ossification.

In a fracture that is rigidly immobilized the fracture heals by the process of intramembranous ossification.

Intramembranous ossification is also an essential process during the natural healing of bone fractures and the rudimentary formation of bones of the head.

Intramembranous ossification is one of the two essential processes during fetal development of the mammalian skeletal system by which bone tissue is created.

The formation of bone during the fetal stage of development occurs by two processes: Intramembranous ossification and endochondral ossification.

Mesenchymal stem cells within mesenchyme or the medullary cavity of a bone fracture initiate the process of intramembranous ossification.

Its lateral end is formed by intramembranous ossification while medially it is formed by endochondral ossification.

Unlike intramembranous ossification, which is the other process by which bone tissue is created, cartilage is present during endochondral ossification.

Like meningocoele, meningohydroencephalocoele is caused by defects in bone ossification; in particular, the intramembranous ossification related to the closure of infantile fontanelles.

Endochondral ossification is the formation of long bones and other bones (except from intramembranous ossification) This requires a hyaline cartilage precursor.

A dermal bone (membrane bone) is a bony structure that is part of the intramembranous ossification (the bone that helps fetus development in mammals).

In the fetus, the formation of the Calvaria involves a process known as intramembranous ossification, although the base of the skull (underlying the brain) develops through endochondral ossification.

A dermal bone or membrane bone is a bony structure derived from intramembranous ossification forming components of the vertebrate skeleton including the skull, jaws, gills, fins and exoskeleton (of tortoises and turtles).

Intramembranous ossification mainly occurs during formation of the flat bones of the skull but also the mandible, maxilla, and clavicles; the bone is formed from connective tissue such as mesenchyme tissue rather than from cartilage.

There are two processes resulting in the formation of normal, healthy bone tissue: Intramembranous ossification is the direct laying down of bone into the primitive connective tissue (mesenchyme), while endochondral ossification involves cartilage as a precursor.
