Summary
Muscles attach to developing Meckel
Area of Science:
- Developmental biology
- Anatomy
- Histology
Background:
- Mandibular development is intricately linked with Meckel's cartilage.
- Muscles of mastication and the trigeminal nerve play crucial roles.
Purpose of the Study:
- To investigate prenatal muscular attachments to the developing mandible.
- To understand the relationship between Meckel's cartilage and muscle development.
Main Methods:
- Histological analysis of serial sections.
- Observation of developing human embryos at various stages.
Main Results:
- Meckel's cartilage serves as an initial attachment site for multiple muscles.
- Muscles like stylohyoid, styloglossus, mylohyoid, genioglossus, geniohyoid, pterygoid, and masseter show attachments.
- Temporary muscle attachments to Meckel's cartilage were observed by stage 18.
Conclusions:
- Muscles attach to Meckel's cartilage by the 10th developmental week before transferring to the mandible.
- Muscle attachments to Meckel's cartilage may influence mandibular movements and potentially cause dislocation.

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...
01:22Sutures 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...

01:12The Hyoid Bone
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...
01:26Muscles of the Anterior Neck
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
01:19Naming Skeletal Muscles
The naming of the approximately 700 muscles in the human body is based on a set of criteria designed to provide descriptive information about each muscle, making it easier to identify and remember them.
The key factors used in naming muscles include:

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...
