What is a neuromuscular junction? Neuromuscular Junctions: Terms used in anatomy and physiology often give clues about what they are describing based on the parts of the words. "Neuro-" refers to the nervous system and the neurons used to transmit signals, while "-muscular" refers to the musc...
The range of diseases affecting the neuromuscular junction (NMJ) is many and varied. Congenital forms due to single gene defects affecting various components of the NMJ include slow channel myasthenic syndrome, choline acetyltransferase deficiency and the recently described DOK-7 mutation.1 Of the ...
Describe how muscle action potentials arise at the neuromuscular junction. (a) Where is soleus located? (b) Explain its action. (a) Where are the internal intercostals located? (b) Explain its action. For the reflex pathway for the milk let-down reflex, what is the e...
beta-Bungarotoxin from the Taiwan banded krait, Bungarus multicinctus is a basic protein (pI = 9.5), with a molecular weight of 21,800 consisting of two different polypeptide subunits. A phospholipase A(2) subunit named the A-chain and a non-phospholipase A(2) subunit named the B-chain,...
(NCSs) and needle electromyography (EMG). EDX tests are often crucial in evaluating symptoms, arriving at a proper diagnosis, and in following a disease process and its response to treatment in patients with neuromuscular disorders...
Nicotinic receptors at the neuromuscular junction activate muscle contraction. 9 Common Curiosities Can both adrenergic and cholinergic receptors be found in the heart? Yes, both types of receptors are present in the heart, but they have opposite effects; adrenergic receptors increase heart rate, while...
EMG and nerve conduction studies are commonly performed together to diagnose whether a neuromuscular disorder is caused by muscle or nerve damage, in order to accurately diagnose and provide appropriate treatment. These tests are generally performed only when physical examination does not reveal the caus...
Autism spectrum disorder (ASD) is a group of complex developmental disorders clinically characterized by behavioral symptoms, such as impaired communication skills, defective social interaction, and the presence of repetitive behaviors [19]. ASD significantly limits the individual’s capacity to live indep...
The reason for this is probably the direct destruction of nerve cells in the nose and the olfactory bulb [19]. Ageusia is, like anosmia, another common cranial nerve disorder that occurs in COVID-19. 2.1.3. Acute Cerebral Vascular Disease Individuals infected with COVID-19 may develop ...
Lambert-Eaton myasthenic syndrome (LEMS) is a rare neuromuscular junction disorder resulting from the development of auto-antibodies against voltage-gated calcium channels (VGCCs) in pre-synaptic terminals (1). Lambert-Eaton Myasthenic Syndrome with A Twenty-Three-Year Delay in Diagnosis More results...
