Summary
Mechanical forces significantly influence craniofacial development by triggering molecular signaling pathways essential for tissue differentiation. Understanding this link is key to unraveling morphogenesis and its underlying biological, chemical, and physical laws.
Area of Science:
- Developmental Biology
- Morphological Sciences
- Molecular Signaling
Context:
- Craniofacial development involves complex molecular signaling pathways.
- Cells respond to mechanical stimuli through biochemical signaling.
- This research revives the developmental mechanics approach, emphasizing physical forces in morphogenesis.
Purpose:
- To review the link between mechanical forces and molecular signaling in craniofacial development.
- To connect contemporary knowledge of tissue differentiation with mechanical aspects of developmental biology.
- To focus on cartilage, bone, and muscle formation in response to specific forces.
Summary:
- Mechanical forces arising from cell and tissue interactions trigger molecular cascades during development.
- Specific forces like pressure (cartilage), shearing (bone), and dilation (muscles) are crucial.
- Detailed morphological knowledge and 3D imaging are vital for understanding force exertion and signal timing.
Impact:
- Highlights the role of mechanical forces as mediators, not creators, of biological form.
- Underscores the need for advanced imaging and force measurement techniques in developmental biology.
- Provides a foundation for future research into the physical regulation of morphogenesis.

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
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,...
