Abstract:
Craniofacial morphogenesis is underpinned by orchestrated growth and form-shaping activity of skeletal and soft tissues in the head and face. Disruptions during development can lead to dysmorphology of the skull, jaw, and the pharyngeal structures. Developmental disorders can be investigated in animal models to elucidate the molecular and cellular consequences of the morphogenetic defects. A first step in determining the disruption in the development of the head and face is to analyze the phenotypic features of the skeletal tissues. Examination of the anatomy of bones and cartilage over time and space will identify structural defects of head structures and guide follow-up analysis of the molecular and cellular attributes associated with the defects. Here we describe a protocol to simultaneously visualize the cartilage and bone elements by Alcian blue and Alizarin red staining, respectively, of wholemount specimens in mouse models.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
