What is the primary genetic mutation responsible for Duchenne Muscular Dystrophy?
Mutations in the DMD1 gene
Alterations in the MYOD gene
Mutations in the DMD gene
Defects in the ACTN3 gene
How does Becker's Muscular Dystrophy differ from Duchenne Muscular Dystrophy in terms of severity?
Becker's Muscular Dystrophy is more severe than Duchenne Muscular Dystrophy.
Becker's Muscular Dystrophy is equally severe in all cases compared to Duchenne.
Becker's Muscular Dystrophy is less severe than Duchenne Muscular Dystrophy.
Becker's Muscular Dystrophy has the same severity as Duchenne Muscular Dystrophy.
What are the common clinical features of Myasthenia Gravis?
Skin rashes and itching
Severe headaches and nausea
Common clinical features of Myasthenia Gravis include ptosis, diplopia, generalized muscle weakness, and difficulty swallowing and speaking.
Joint pain and swelling
Which neurotransmitter is primarily affected in Myasthenia Gravis?
Acetylcholine
Norepinephrine
Dopamine
Serotonin
What is the role of dystrophin in muscle function?
Dystrophin regulates blood flow to the muscles during activity.
Dystrophin helps in the contraction of muscle fibers during exercise.
Dystrophin is responsible for energy production in muscle cells.
Dystrophin plays a crucial role in maintaining muscle cell integrity and function.
Describe the inheritance pattern of Duchenne Muscular Dystrophy.
Autosomal dominant inheritance
X-linked recessive inheritance
Mitochondrial inheritance
Y-linked inheritance
What are the potential complications associated with Becker's Muscular Dystrophy?
Potential complications include respiratory issues, scoliosis, cardiomyopathy, and reduced mobility.
Increased appetite and weight gain
Improved cardiovascular health and stamina
Enhanced muscle strength and endurance
How do smooth muscle disorders typically present clinically?
Manifestations including headaches, dizziness, and vision problems.
Symptoms like joint pain, fatigue, and skin rashes.
Signs such as fever, weight loss, and muscle weakness.
Symptoms such as abdominal pain, dysphagia, urinary retention, and respiratory issues.
What is the mechanism of action of acetylcholinesterase inhibitors in Myasthenia Gravis treatment?
They inhibit acetylcholinesterase, increasing acetylcholine availability at the neuromuscular junction.
They block acetylcholine receptors at the junction.
They enhance acetylcholine breakdown at the synapse.
They increase dopamine levels in the neuromuscular system.
Explain the significance of genetic counseling in families affected by muscular dystrophies.
Genetic counseling provides a cure for muscular dystrophies and eliminates symptoms.
Genetic counseling is significant as it aids families in understanding muscular dystrophies, their inheritance, and provides support for informed decision-making.
Genetic counseling is primarily focused on physical therapy for muscular dystrophies.
Genetic counseling is only relevant for individuals diagnosed with muscular dystrophies.
