Musculoskeletal system class Flashcards
What is the musculoskeletal system comprised of?
Muscle, Bones, Joints, Tendons, Ligaments, cartilage
What is the purpose of the Musculoskeletal system?
- Support for the body structure by stabilizing the joints
- Protecting internal organs
- framework for body
What are Bones
Rigid connective tissue- provides the skeleton structure
What are muscles
Bundle of cells that contract and produce movement
What are joints
Location where the bones make contact- provide movement and mechanical support
What are tendons
Bands of fibrous tissue that connects muscle to bones
What are ligaments
Fibrous tissue that connect bones OR cartilage; supports and strength joints
What is cartilage
connective tissue at the end of bones that reduce friction between the bones
What are the two main component of the musculoskeletal system
Bones and muscles
What are medical conditions that related to the musculoskeletal system
Rheumatoid arthritis Gout Myasthenia gravis Osteoporosis Osteomalacia Muscle spasms
What are the major drug groups in the musculoskeletal system
NSAID Corticosteroids COX II inhibitor DMARDs Bone Therapy Gout Non- opioid Analgesics Muscle relaxants
What are NSAIDs
Non steroidal Anti- Inflammatory drug that blocks prostaglandin production.
What is the route of administration for NSAIDs
PO and PR
What are Corticosteroids
Steroids that occur naturally in the body which block prostaglandins and depress accumulation of WBC
What is the route of administration of corticosteroids
Injection. Usually directly into the affected site
What hormone is blocked by NSAIDs
Prostaglandin
Corticosteroids block which hormones?
Prostaglandin and WBC (white blood cells)
What is a intrathecal injection
injection Into the space around the spinal cord
What is a intra articular inject
injection directly into the joint
what is the difference between blocking a COX I versus a COX II enzyme
COX I sometimes leads to stomach irritation
what are antipyretics
Fevers
What are DMARDS?
Drugs that can potentially modify disease progression
What do DMARDs do
Work to decrease pain and inflammation, to reduce/ prevent joint damage, and to preserve the structure/ function of the joints
What is an axillary label for DMARDs?
Avoid prolonged or excessive exposure to direct and/or artificial sunlight
