Disorders of the Skeletal Muscle

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

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,...

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cranial Bones: Lateral View

Cranial Bones: Lateral View

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...

Naming Skeletal Muscles

Naming 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:

Muscles for Facial Expressions

Muscles 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...

Summary

This summary is machine-generated.

Rarer than usual, muscular tumors like rhabdomyoma are seldom found in jaws. Diagnosis relies on histopathology, with surgical excision as the primary treatment for these jaw tumors.

Area of Science:

Oncology
Pathology
Oral Surgery

Context:

Muscular tumors are exceptionally rare in the jaw.
Rhabdomyoma, a specific type of muscular tumor, has not been previously reported in the jaw.
Clinical and radiological presentations of these tumors are often non-specific.

Purpose:

To discuss the diagnostic challenges and treatment strategies for muscular tumors in the jaw.
To highlight the rarity of rhabdomyoma in this anatomical location.
To differentiate between benign and malignant muscular tumors of the jaw.

Summary:

Muscular tumors rarely occur in the jaw, with rhabdomyoma being an unreported entity in this site.
Histopathological examination is crucial for diagnosis, especially for distinguishing leiomyosarcoma.
Treatment varies from conservative excision for benign tumors (leiomyoma) to radical surgery for malignant counterparts.

Impact:

This review emphasizes the importance of considering rare muscular tumors in jaw lesion differential diagnoses.
It clarifies the diagnostic and therapeutic approaches for oncologists and oral surgeons.
Understanding the prognostic differences between benign and malignant muscular tumors aids in patient management.
