Abstract:
We report the case of an unusual presentation of myasthenia gravis with tongue atrophy and fasciculation. Myasthenia gravis is an autoimmune condition associated with weakness and fatigability of voluntary muscles. In >50%, the initial symptoms and signs are related to extraocular muscle weakness, such as diplopia or ptosis [Tsung K, Seggev JS. An unusual cause of dysphagia. West J Med 1995; 163: 159-60]. Rarely, it is known to affect bulbar muscles and can lead to dysphagia and respiratory compromise.

Chemical Synapses
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...

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...
