Exam Prep Flashcards
What does muscle insertion refer to?
The muscle insertion is attached to the more mobile bone, usually more distal
What is kyphosis?
Kyphosis is the hunchback of the spine. Kyphosis is defined as a curvature of the spine measuring 50 degrees or greater on an X-ray
What is more superior, the nose or the knees?
Nose
What is inflammation?
Response to tissue damage or threat of invasion by antigens.
What is inflammation triggered by? (4)
- physical trauma
- hormones
- invasion with foreign bodies
- autoimmune activity
What is the purpose of inflammation?
Protect from pathogenic invasion, limit contamination, prepare damaged area for healing
Common causes of tissue damage?
- trauma
- infection
- surgery
- immune responses
- ischemic damage
- chemical/radiation damage
- extreme heat/cold
What is vasoconstriction ?
The constriction of blood vessels, which increases blood pressure.. Vasoconstriction is short lived, and protective
Mast cells?
- located in tissues vulnerable to injury
- release histamines to prolong inflammatory response
Monocytes and macrophages?
WBC’s
Monocytes: large, white, mobile blood cells
Macrophages: permanently fixed monocytes
associated with end stage inflammation, clean up debris
What year did the Society of Trained Masseuses begin?
1895
What year was massage introduced as it’s own profession in the US?
1917
What is vasodilation?
Widening of blood vessels. Caused by chemicals released by endothelium and mast cells.
What does vasodilation do?
- increases permeability of capillaries
- reinforces capillary dilation
- attracts platelets
- slows blood away from the area
What are the components of inflammation?
- vascular: vasoconstriction and vasodilation
- cellular: endothelial cells, platelets, WBC’s
- chemical mediators
Lymphocytes?
- work with macrophages to clean up debris
- promote scar tissue
- angiogenesis (new blood vessels)
Fibroblasts?
- produce collagen
- drawn to local blood clots, proliferate (increase rapidly) to form new scar tissue
Granulocytes?
- smallest, fastest
- neutrophils first on the scene for bacterial infection, musculoskeletal injury
- eosinophils for allergies, parasites
- basophils for allergies and histamine release
What are the 3 types of granulocytes?
- neutrophils
- eosinophils
- basophils
What are the 2 types of healing?
Primary/ 1st intention: occurs when there is some tissue loss, wound edges are approximated
Secondary/ 2nd intention: occurs when there is extensive tissue loss, wound edges do not meet/ cannot be brought together easily. Healing takes longer
What takes longer to heal, Primary/ 1st intention or secondary/2nd intention healing?
Secondary/ 2nd intention healing takes longer
What are the stages of healing? (4)
Acute
Subacute
post acute/ late acute
chronic inflammation
What happens in the acute stage of healing?
- damaged cells release chemicals
- edema develops
- platelets, early WBC’s arrive
- tissue exudate (pus, fluid) begins to form
How long is the acute stage?
Depends on severity, 1-3 days usually
What is the subacute stage also called?
proliferate stage
What happens in the subacute stage?
- cells accumulate to fill in damaged area: endothelial cells fill in to grow new capillaries, fibroblasts create collagen fibers
- slower WBC’s arrive to start cleanup
How long is the subacute stage?
depends, early subacute is usually 2 days to 3 weeks
What happens in the post acute/ late acute stage?
-collagen becomes denser and aligns according to force
What is the post/ late acute stage also called?
maturation stage
How long does the post/ late acute stage last?
generally the 2nd to 3rd week of the subacute stage
What is chronic inflammation?
-Happens when the inflammatory process is not successful
What does chronic inflammation cause?
- pathogens/ irritants are not removed (leads to cysts, abscesses)
- extensive scar tissue interferes with organ function (sinuses of fistula develop)
- musculoskeletal structures never regain full function (tendinosis)
- excessive external scar tissue
How long does chronic inflammation last?
overlaps latter part of subacute and can continue for up to 1-2 years
What are the signs and symptoms of inflammation? (5)
- dolor (pain)
- calor (heat)
- rubor (redness)
- tumor (swelling)
- functio laesa (loss of function)
What is the acronym for signs and symptoms of inflammation?
S: swelling H: heat A: associated symptoms R: redness P: pain
