Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.0K
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...

Myasthenia Gravis: Overview and Treatment

1.8K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Gastrointestinal Motility Disorders

548
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Myasthenia Gravis: Diagnostic Tests

1.2K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Layers of Connective Tissue Proper

2.0K
Fascia, a thin layer of fibrous connective tissue, is distributed throughout the body. It demarcates and forms a supportive covering over skeletal muscles, bones, blood vessels, and organs. There are three main types of facia— superficial fascia, deep fascia, and subserous fascia. These are all present at different depths in the body. Fascia reduces the friction and permits muscles, joints, and organs to easily slide against each other, facilitating movement of the body and preventing...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

2.4K
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...

Area of Science:

  • Orofacial Pain Management
  • Myofascial Pain Syndromes
  • Neuromuscular Dentistry

Background:

  • Masticatory myofascial pain disorders (MMPD) are prevalent orofacial pain conditions.
  • Common comorbidities include headaches, cervical disorders, chronic widespread pain, and psychosocial issues.
  • The multifactorial nature of MMPD necessitates a comprehensive treatment strategy.

Purpose of the Study:

  • To describe a complex case of MMPD.
  • To review current literature on MMPD classification and pathophysiology.
  • To discuss evidence-based treatment planning for MMPD.

Main Methods:

  • Case study presentation.
  • Comprehensive literature review.
  • Analysis of classification, pathophysiology, and treatment modalities.

Main Results:

  • The presented case exhibited typical MMPD characteristics.
  • Literature supports a multifactorial pathophysiology for MMPD.
  • Multimodal and interdisciplinary treatment is recommended.

Conclusions:

  • Effective MMPD management requires addressing pain, disability, mandibular function, and quality of life.
  • An integrated approach combining various therapeutic strategies is crucial.
  • Further research into evidence-based treatment planning is warranted.
