Med Term - 6: Musculoskeletal System Flashcards
What is the function of the musculoskeletal system?
protection
support
movement
Bones are essential in what?
hematopoiesis
storage of fat in bone marrow

skull
spinal column
breastbone
ribs
What is cartilage?
specialized type of dense connective tissue that is elastic, strong, and can withstand pressure and tension
What are the three types of skeletal muscle?
cardiac
smooth
skeletal
Fascia
covers, supports, and separates muscles
Tendons
attach muscles to bones
Joint
place of union between two or more bones
Where are synovial joints located?
in the cavities between bones
Ligaments
connect bones or cartilage
What diseases have unknown causes?
fatigue syndrome
fibromyalgia
myofibrosis
myasthenia gravis
Fibromyalgia
widespread non-particular pain of torso, extremities, face
Myofibrosis
tissue replaced by fibrous tissue
Myoasthenia gravis
fatgiue and muscle weakness resulting from a defect in nerve impulse conduction
What are the various stress and trauma injuries?
dislocation fracture sprain strain herniated disks paraplegia quadriplegia/tetraplegia paresis paraparesis quadra/tetraparesis
Dislocation
displacement of bone from a joint
Fracture
broken bone
Sprain
injury to joint that causes pain and disability
Strain
excessive use of body resulting in injury or trauma due to contraction or excessive stretch
Herniated Disks
occurs when vertebrae become diseased and rupture
Paraplegia
paralysis of lower portion of body and both legs
Quadri/tetraplegia
paralysis of arms and legs
Paresis
motor weakness or partial paralysis
Paraparesis
partial paralysis of lower limbs
Quadra/Tetraparesis
affects all four extremities
What are the various infections of the musculoskeletal system?
cellulitis
osteitis
osteomyelitis
osteochondritis
Cellulitis
acute, spreading inflammation of deep subcutaneous tissue
Osteitis
inflammation of bone
Osteomyelitis
infection of bone and bone marrow caused by infectious organisms
ostechondritis
inflammation of bone and cartilage that attacks ossification centers
What are the two types of tumors?
primary
secondary
Primary tumor
originates in bone
Secondary tumor
originating in other tissue
Sarcomas
cancers that arise from connective tissue
Chondrosarcomas
composed of masses of cartilages
Fibrosarcoma
malignant tumor that contains fibrous tissue
Leukemias
chronic or acute disease of blood-forming tissues, causing unrestrained growth of leukocytes
How are leukemias classified?
predominant cell types
severity of disease
Multiple myeloma
presence of many masses in bone marrow that is progressive and fatal
Paget Disease
osteitis deformans
skeletal disease of elderly persons
chronic bone inflammation
What are the types of metabolic disturbances of the musculoskeletal system?
osteitis deformans (paget disease)
osteomalacia
spondylomalacia
osteoporosis
Osteomalacia
reversible skeletal disorder caused by a vitamin D deficiency that affects the mineralization of bone
Spondylomalacia
softening of the vertebrae
Osteoporosis
reduced bone mass common in postmenopausal women, sedentary individuals, and those who are using long term steroid therapy
What is common in osteoporosis patients
Dowager’s hump
What are the various congenital defects of the musculoskeletal system?
spina bifida scoliosis kyphosis muscular dystrophy carniocele tarsoptosis
Spina bifida
defective closure of bones of spine
Scoliosis
lateral curvature of spine
Kyphosis
exaggerated curvature of spine from front to back
Craniocele
hernial protrusion of brain through defect in skull
Tarsoptosis
flat foot
What are the various types of arthritis and connective tissue diseases?
arthritis osteoarthritis/degenerative joint disease rheumatoid arthritis spondyloarthritis rheumatoid spondylitis ankylosis polyarthritis arthralgia/arthrodynia bursitis lupus erythematosus gout arthropathy
Arthritis
any inflammatory condition of joints, characterized by pain, heat, swelling, redness, and limited movement
Osteoarthritis
DJD
loss of articular cartilage that is common in joints that bear weight
Rheumatoid Arthritis
second most common connective tissue disease that is chronic, systemic and often results in joint deformities in hands and feet
Rheumatism
acute chronic conditions characterized by inflammation, soreness, and stiffness of muscles, pain in joints and associated structures
Spondyloarthritis
inflammation of vertebrae, arthritis of spine
Rheumatoid spondylitis
causes inflammation of cartilage between vertebrae and may cause neighboring vertebrae to fuse
Ankylosis
immobile and stiff joint that can occur in spine
Polyarthritis
inflammation of more than one joint
Arthralgia/Arthrodynia
painful joint
Bursitis
inflammation of bursa that may not include inflammation of actual joint
LupusErythematosus
autoimmue diease that involves connectie tissue and commonly is first identified by the butterfly rash
Gout
hereditary acute arthritis that causes inflammation of joints (feet, knee)
Arthropathy
any disease of a joint
Reduction
returning fractures to normal positions and may or may not require surgery
External fixation
uses metal pins attached to compression device outside skin surface
Internal fixation
pins, rods, plates, screws etc to immobilize a fracture
Anti Osteoporotic
used along with calcium therapy, vitamin D, and estrogen therapy to treat osteoporosis
