Muscles that Move the Head

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Articulations of the Vertebral Column

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Cranial Bones: Superior and Posterior View

Cranial 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,...

Sutures of the Skull

Sutures 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...

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis

Summary

This study found no link between head posture and temporomandibular disorders (TMD) in dental students. Abnormal head postures were common in both individuals with and without TMD.

Background:

Temporomandibular disorders (TMD) are common, and head posture is a potential contributing factor.
Understanding the relationship between head posture and TMD is crucial for diagnosis and treatment.

Purpose of the Study:

To investigate the correlation between head posture (frontal and sagittal planes) and the prevalence of TMD in dental students.
To determine if specific head postures are associated with an increased risk of developing TMD.

Main Methods:

A cross-sectional study involving undergraduate dental students.
TMD diagnosis using Research Diagnostic Criteria (RDC)/TMD axis I.
Head posture assessment using craniovertebral angle (sagittal) and interpupillary line (frontal) via SAPO software.

Main Results:

No significant association was found between head posture in the frontal or sagittal planes and the occurrence of TMD.
Abnormal head postures were prevalent in both individuals with and without TMD.
No sex-based differences were observed in the association between head posture and TMD.

Conclusions:

Head posture in the frontal and sagittal planes, as evaluated, is not associated with TMD diagnosis in this student population.
Further research may be needed to explore other potential factors influencing TMD development.
