Skeletal Muscle Anatomy

92.5K
Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

Bone Markings01:26

Bone Markings

7.8K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.6K
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...

Gross Anatomy of Skeletal Muscles

The connective tissues play a significant role in arranging the muscle fibers into a hierarchical structure that forms a complete muscle. Consider a muscle like the bicep brachii, commonly called the bicep. This muscle comprises thousands of muscle fibers enclosed by a protective layer of connective tissue called the endomysium. The endomysium is primarily composed of reticular fibers, a type of thin collagen fiber. It allows the exchange of nutrients and waste products at the fiber level,...

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...

Microscopic Anatomy of Skeletal Muscles

Skeletal muscle cells, also called muscle fibers, are distinctly elongated, multi-nucleated, slender biological units. They are packed with specialized structures designed to facilitate their primary function, which is contraction.
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...

Summary

This review covers common vascular tumors in bone, including hemangiomas and aggressive neoplasms. It details their appearance using multiple imaging methods for diagnosis.

Area of Science:

  • Musculoskeletal Radiology
  • Oncology
  • Vascular Biology

Background:

  • Vascular lesions of bone are common neoplasms.
  • Accurate diagnosis is crucial for appropriate management.
  • Multimodality imaging is essential for characterizing these lesions.

Purpose of the Study:

  • To review the imaging appearance of various musculoskeletal vascular lesions.
  • To highlight the utility of multimodality imaging in diagnosing these conditions.
  • To provide a comprehensive overview of benign and malignant vascular bone tumors.

Main Methods:

  • Literature review of musculoskeletal vascular lesions.
  • Analysis of imaging characteristics across different modalities (e.g., MRI, CT, Ultrasound).
  • Discussion of associated syndromes and differential diagnoses.

Main Results:

  • Detailed descriptions of imaging findings for osseous hemangioma, glomus tumors, and angiomatosis.
  • Review of rare conditions like Gorham disease and tumor-induced osteomalacia.
  • Characterization of aggressive vascular neoplasms such as hemangioendothelioma, hemangiopericytoma, and angiosarcoma.

Conclusions:

  • Multimodality imaging is key to diagnosing diverse vascular bone lesions.
  • Understanding the imaging spectrum aids in differentiating benign from malignant entities.
  • Recognition of associated syndromes improves diagnostic accuracy and patient care.
