Cross-bridge Cycle01:26

Cross-bridge Cycle

125.8K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Chemical Synapses01:26

Chemical Synapses

12.9K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Disorders of the Skeletal Muscle

2.4K
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 ll: Pathophysiology

14
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...

Myasthenia Gravis: Overview and Treatment

3.7K
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...

Area of Science:

  • Neurology
  • Peripheral Nervous System Disorders

Background:

  • Neuralgic amyotrophy (NA) is a distinct peripheral nervous system (PNS) disorder.
  • Characterized by sudden neuropathic pain and muscle weakness in the upper extremities.

Observation:

  • Lesions commonly affect the upper brachial plexus (BP) and its branches.
  • Causes remain unknown, but triggers include infection, trauma, and exercise.
  • NA presents a spectrum of atypical cases, including lower BP or lumbosacral plexus involvement.

Findings:

  • Functional prognosis is often less favorable than previously assumed.
  • Specific therapies for NA are yet to be established.

Implications:

  • Highlights the need for further research into NA pathogenesis.
  • Emphasizes the importance of recognizing atypical presentations.
  • Underscores the urgent requirement for developing targeted therapies for NA patients.
