Summary
This special issue explores the zygoma (cheek bone), detailing its development, structure, and function in mammals, particularly primates. It highlights the zygoma
Area of Science:
- Anatomy and Morphology
- Paleontology
- Evolutionary Biology
Background:
- The zygoma, or cheek bone, is a critical element of the craniofacial skeleton.
- It serves as a connection between midfacial and cranial structures.
- It is integral to masticatory muscle origins and facial buttressing.
Discussion:
- This volume presents studies on the development, structure, and function of the zygoma in mammals, with a focus on primates.
- The zygoma's role in phylogenetic relationships and aesthetic significance in humans is also considered.
- Clinical literature on zygoma restoration after trauma is extensive.
Key Insights:
- The zygoma's multifaceted role in craniofacial biomechanics and evolution is emphasized.
- Studies cover its developmental pathways and structural integrity.
- Functional significance in mastication and facial support is a key theme.
Outlook:
- Future research will explore zygoma variation and evolution across all vertebrates in Volume 2.
- Understanding zygoma development and function provides insights into craniofacial evolution.
- Further investigation into its phylogenetic importance is warranted.

01:08Overview of the Skull
8.5K
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...

01:14Muscles for Facial Expressions
5.4K
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...

01:27Cranial Bones: Lateral View
7.7K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...

01:29Bone Formation by Intramembranous Ossification
12.6K
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 ...

01:12The Hyoid Bone
5.9K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

01:22Sutures of the Skull
13.9K
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...
