Physiology/Anatomy Flashcards
What are Intrafusal muscle fibers responsible for?
They detect the amount and rate of change of the length in the muscle
-also called muscle SPINDLES
cyclooxygenase isoenzymes
COX-1 and COX-2,
They catalyze the formation of prostaglandins, thromboxane, and levuloglandins.
Medications that inhibit cox1 and cox 2 are antiinflammatories- like molaxicam etc Celebrex
Nonsteroidal anti-inflammatories block prostaglandin production by directly inhibiting which enzyme?
cyclooxygenase isoenzymes
locations of high-risk stress fracture
-femoral neck (tension side),
-patella, anterior tibia,
-medial malleolus,
-talus,
-tarsal navicular,
-proximal fifth metatarsal, and
-great toe sesamoids.
These sites share a characteristic region of high tensile load and low blood flow.
NSAIDS
pain reliever, dec inflammation
side effects: GI- ulcer, bleeding upset
possible delayed bone healing
morphine -
no longer recommended- addictive, respiration depression
acetylsalicylic acid- apirin
reduce inflammation, pain reliever
-nausea, gastric bleeding, prolongs blood clotting times
beta agonists
management f asthma
side effect- racing heart
human growth hormone
-incr lean body mass
-premature closure of bone growth sites
-acromegaly
-diabetes
Creatine monhydrate
-incr lean body mass, enhance recovery,
-mm cramping, diarrhea, incr renal load
nutritional anticatabolics
slow degradation of protein, decrease breakdown of glutamine, leucine, why , casein, protein
what are innervated by axillary nerve?
deltoid and teres minor
What are innervated by suprascapular Nerve?
Supraspinatus
infraspinatus
teres major
subscapularis
what is innervated by sub scapular nerve?
inf portion of subscapularis
teres major
