muscular disorders Flashcards
myopathy
disorders affecting skeletal muscles= structure channel or metabolisim
muscle fibres dont function properly
hypertrophy
enlargement of muscle cells
atrophy
decline is size of muscle cells
symptoms of myopathy
proximal symetricial limb weakness and preserved reflexes
muscle pain
muscle hypertrophy or atrophy
4 types of inherited myopathy
dystrophies
congenital myopathy
mitacondrial myopathy
metabolic myopathy
acquired myopathy from
drug induced- glucocorticoid steroids
toxic agents
dermatomyositis
polymyositis
inclsuion body myositis
myositis ossification
muscular dystrophy
groups of heritary progressive skeletal muscle weakness defects in muscle protiens causing death in muscle cells
no cure
aerobic exercise
low intensity steroids to treat
muscular dystrophy signs and symptoms of Duchene
wadding gait
calf deformation
muscle spasm
limited ROM
respiraatory diffficulties
progressive weakness
fibromyalgia
muscle and connective tissue pain
fibromyaliga symptoms
pain/ muscle fatigue/ muscle stiffness/ insomina/ blurred vision/difficulty swallowing/ difficukty in bowl and bladder
myasthesia gravis
autoimmune which effects the neuromuscular juction
autoantibodies destory acetylcholine
weakness in muscle
usually in eye lids eye movements
muscle become progressive weaker in the activity
inflammatory muscle diseases
due to immune- mediated muscle injuries
unknown causes
idiopathic
polymyositis
involve inflammation by cytoxic T cells
dermatomyositis
activation of complement cause vascular destruction
infectious myositis
infection in muscle occur in haemtogenisis leads to ability to spread
and invade
