Summary
In vivo skull studies in monkeys challenge traditional ideas about jaw muscles and facial structure. New findings suggest current models of craniofacial architecture need revision based on experimental data.
Area of Science:
- Primatology
- Biomechanics
- Craniofacial Biology
Background:
- Conventional explanations link upper facial morphology to masticatory function using static models.
- Previous studies often rely on theoretical frameworks rather than in vivo experimental verification.
Purpose of the Study:
- To investigate skull biology and geometry using in vivo measurements in growing African green monkeys.
- To analyze the relationship between bite force, bone strain, and jaw muscle function.
Main Methods:
- In vivo measurements of bite force and bone strain were conducted on African green monkeys.
- Data analysis focused on strain values and distributional patterns during forceful jaw elevation.
Main Results:
- Strain patterns observed were inconsistent with conventional explanations of craniofacial architecture.
- The study found discrepancies between experimental data and theoretical models of masticatory function.
Conclusions:
- Experimental in vivo data necessitate a reevaluation of static analysis models for skeletal geometry.
- Conventional ideas on force generation and dissipation by jaw elevator muscles require revision.

Overview 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...

Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
