Study Notes
Musculoskeletal System Overview
- The musculoskeletal system comprises muscles, tendons, ligaments, and bones, working with the nervous and endocrine systems for coordinated movement.
- Healthy nerve signals, muscle tissue, and endocrine function are crucial for strong, coordinated movements.
- The nervous system controls muscle contraction and relaxation, enabling actions like using a spoon.
- The human skeleton has 206 bones, providing structure and mineral storage.
- Calcium is vital for nerve, bone, and muscle function. Adequate calcium storage is necessary for preventing bone fractures.
Calcium Regulation
- The endocrine system regulates calcium levels.
- Calcitonin, produced by the thyroid gland, promotes calcium retention in bones.
- Parathyroid hormone (PTH), from the parathyroid glands, increases blood calcium levels, drawing calcium from bones.
- Imbalances in these hormones can lead to bone abnormalities and altered muscle function.
- Other minerals like magnesium and potassium also affect musculoskeletal function.
Musculoskeletal Medications
- Medications to treat musculoskeletal disorders are categorized into muscle and bone treatments.
- Muscle disorders range from brain-originated conditions (cerebral palsy, stroke) to muscle tissue issues (muscle spasms, dystonia, muscular dystrophy, myasthenia gravis, fibromyalgia).
- Muscle relaxants (e.g., cyclobenzaprine) and antispasmodics (e.g., metaxalone) relax muscles and relieve spasms by acting on the central nervous system. Some are benzodiazepines, like diazepam.
- Newer treatments, like duloxetine, address chronic pain by targeting the stress associated with it.
- Botulinum toxin type A (Botox) directly weakens muscles by blocking acetylcholine release.
- Myasthenia gravis involves a loss of acetylcholine receptors, causing muscle weakness and fatigue, treated by cholinesterase inhibitors like neostigmine.
- Fibromyalgia is chronic muscle and soft tissue pain treated by physical therapy, antidepressants, and anti-inflammatories.
- Treatment for low calcium (hypocalcemia) includes calcium supplements and sometimes vitamin D to aid absorption.
- Risk factors associated with hypocalcemia include smoking, lack of exercise, alcohol consumption, anorexia, hormonal deficiencies, poor nutrition, and obesity. Calcitonin (Miacalcin) is a nasal or injectable option to boost calcium in bones.
Bone Disorders and Medications
- Osteoporosis (porous bones) and osteomalacia (soft bones) are linked to calcium deficiency.
- Osteoporosis results in weakened bones prone to fractures.
- Estrogen replacement therapy (ERT) can inhibit bone resorption but has potential risks, including cancer and blood clots.
- Bisphosphonates (e.g., alendronate) are a similar alternative to ERT with fewer side effects.
- Paget's disease involves excessive bone resorption, leading to weak, deformed bones susceptible and painful fractures. Treatment involves calcitonin and bisphosphonates, with potential supplementary calcium and vitamin D.
Arthritis and Related Conditions
- Arthritis includes osteoarthritis (bone degeneration at joints) and rheumatoid arthritis (autoimmune joint inflammation).
- Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, are common treatments for both types.
- Gout is characterized by uric acid buildup in joints, often the big toe, with sudden pain. Initially, NSAIDs (high doses during attacks, lower for prevention) or colchicine are used to alleviate the acute phase.
- Long-term management of gout involves antigout medications such as allopurinol or febuxostat to lower uric acid.
- COX-2 inhibitors (like celecoxib) target specific inflammation enzymes to reduce ulcers and bleeding while managing arthritis pain.
- Disease-modifying antirheumatic drugs (DMARDs) suppress the immune system's harmful response in rheumatoid arthritis. Examples include methotrexate and gold-based treatments.
Other Relevant Conditions
- Corticosteroids (like dexamethasone) reduce inflammation by mimicking the body's natural hormone, but they are short-term solutions due to immune system interference.
- Capsaicin topical medications offer pain relief by affecting nerve signals in conditions like diabetic neuropathy.
- Phantom limb pain is experienced as pain in a missing limb, and is usually managed with tricyclic antidepressants, anticonvulsants, or narcotics.
