15 Cards in this Set

  • Front
  • Back
forms an interocious membrane, found between radius and ulna, more fibrous conn tissue than a suture
immovable interlocking joints keeping cranial bones together.
-post. fontanel closes 3 mos after birth
-inf. fontanel closes 18-24 mos after birth
muscle fiber contractile units made of repeating segments called sacromere
-thick myosin
-thin actin
sarcoplasmic reticulum surrounds.
filaments slide overeachother every contraction
Sarcoplasmic Reticulum
surrounds every myofibrile, responsible for storing/releasing calcium.
T-tubules on every side delivering impulse to deepest myofibrile
Synvoial Membrane
loose connective tissue found between 2 articulating bones is articular cartilage
-preventing rubbing wear and tear causes erosion.
-egg white consistancy
-delivers nutrients to chondrocytes and gets rid of waste and microbes w/ hylauronic acid
Cardiac Tamponade
too much fluid around heart, leads to failure
white blood cells squeezing through tiny spaces between forming capillaries
connecting material in a broad flat disc of fibrocartilage
connects 2 bones together, made of hyaline cartilage
-eg. epiphyseal plate
Pericardial Fluid
heart contracts, layers do not rub due to fluid preventing friction
neurotransmitter, chemical from nervous system
-every muscle fiber has nerve
-paralysis is nerve cut off, no contracting
-neuromuscular junction is point of contact between muscle/nerve (releasing of nerve)
-impulse spread all over muscle, go down T-tubule
-red blood cells formed in red bone marrow
-formed through erythropoiesis
-lifespan of 120 days
-removed from circulation by macrophages in liver
-began as pre, maturing to erythroblast synthesizing hemoglobin
-has nucleus until blast stage
-depression allows for oxygen holding
Reticulocyte Count
rate of formation
-releasing when deepest myofibrile is stimulated
-initiates muscle contraction
-makes actin and myosin contract
-binds to troponin tropomyosin complex, opens once binded
Saphenous Vein
-venous valves help push blood in veins back to heart preventing backflow
-16 to 18 valves located in leg
-when calph muscle contracts squeezes into valves push blood up
-faulty w/ age becoming weak/distorted called 'varicose'
