The cartilaginous viscerocranium, comprising the splanchnocranium In comparative anatomy of vertebrates, viscerocranium usually refers specifically to the splanchnocranium (as opposed to the endocranium and dermatocranium) This disambiguation page lists articles associated with the title Viscerocranium. During the 6th week, the skull begins to develop, consisting of the neurocranium, which encloses the brain, and the viscerocranium, which supports the face and upper airway. This forms the ear bones and hyoid bone. a dense connective tissue composed of a matrix produced by cells called chondroblasts, which become embedded in the matrix as chondrocytes.It is a semiopaque grey or white substance, consisting chiefly of chondroitin sulphate, that is capable of withstanding considerable pressure.There are three types: hyaline cartilage, elastic cartilage, and fibrocartilage.

Synchondrosis is a type of cartilaginous joint in which the cartilage is usually converted into bone before adult life. The skull formation was in mesenchymal form at 26 days. The bones that make up the skull thus form either by intramembranous ossification or endochondral ossification. The mandibular and hyoid arches collectively make up the facial skeleton, also known as the viscerocranium. A combined, undivided effort or undertaking involving two or more individuals. The membranous viscerocranium is formed by a process of intramembranous ossification, whereas the cartilaginous viscerocranium utilizes the endochondral ossification to form bones.
