What does the disorder PANDAS mean?
PANDAS stands for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections. It is a condition in which a streptococcal infection triggers an autoimmune response that affects the brain, leading to sudden onset of symptoms such as obsessive-compulsive disorder (OCD) and tics in children. Treatment typically involves antibiotics and immunomodulatory therapy.
An autoimmune disorder in which joints are affected bilaterally and which involves pannus formation and gradual joint immobilization is?
Sounds like Rheumatoid Arthritis.
What is a neuromuscular disorder characterized by relapsing weakness of skeletal muscles?
Myasthenia gravis is a neuromuscular disorder characterized by muscle weakness and fatigue, typically worsening with activity and improving with rest. It is caused by an autoimmune response that targets acetylcholine receptors at the neuromuscular junction, leading to impaired communication between nerves and muscles. Treatment often involves medications that help improve nerve impulse transmission and reduce symptoms.
Why the release of acetylcholine at the neuromuscular junction is not considered a hormonal event?
The release of acetylcholine at the neuromuscular junction is not considered a hormonal event because it involves the transmission of a neurotransmitter (acetylcholine) between nerve cells and muscle cells, which occurs locally and rapidly. Hormones are typically produced by endocrine glands, circulated through the bloodstream, and have slower and longer-lasting effects on target cells throughout the body.
Autoimmune disorder with extensive demyelination?
Multiple sclerosis is an autoimmune disorder characterized by extensive demyelination of the nerve fibers in the central nervous system. The immune system mistakenly attacks the myelin sheath, leading to impaired nerve function and potential neurological symptoms such as weakness, numbness, and vision problems. Treatment often involves medications to reduce inflammation and modify the immune response.
What is the transmission of the stimulus at the neuromuscular junctions involves?
The transmission of the stimulus at the neuromuscular junction involves the release of acetylcholine from the motor neuron, binding to acetylcholine receptors on the muscle cell membrane, causing depolarization of the muscle cell, and ultimately leading to muscle contraction.
Which of these is the neurotransmitter associated with laughter?
Endorphins : "Humor involves the brain's reward system, which mainly uses dopamine as its neurotransmitter."
What is Disorder that involves mood swings that interfere with everyday living?
polar disorder
What type of immune response is always disadvantageous to a person?
An autoimmune response is always disadvantageous to a person, as it involves the immune system attacking the body's own healthy cells and tissues. This can lead to chronic inflammation, tissue damage, and various autoimmune diseases.
Impulse disorder which involves setting fires?
Pyromania.
What is ciliacs disease?
Celiac disease is an autoimmune disorder where consuming gluten triggers an immune response that damages the small intestine. This can lead to various symptoms like bloating, diarrhea, and fatigue. The treatment involves a strict gluten-free diet.
What causes Goodpasteur's syndrome?
Goodpasture syndrome is a rare disease that involves rapidly progressive kidney failure along with lung disease. some forms of this disease can involve just the lung or kidney but not both. This is an autoimmune disorder where the immune system mistakenly attacks the body and destroys healthy body tissue.
