|
Syndesmosis
|
forms an interocious membrane, found between radius and ulna, more fibrous conn tissue than a suture
|
|
|
Suture
|
immovable interlocking joints keeping cranial bones together.
-post. fontanel closes 3 mos after birth -inf. fontanel closes 18-24 mos after birth |
|
|
Myofibrile
|
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
|
|
|
Diapedesis/Emigration
|
white blood cells squeezing through tiny spaces between forming capillaries
|
|
|
Symphysis
|
connecting material in a broad flat disc of fibrocartilage
|
|
|
Synchondrosis
|
connects 2 bones together, made of hyaline cartilage
-eg. epiphyseal plate |
|
|
Pericardial Fluid
|
heart contracts, layers do not rub due to fluid preventing friction
|
|
|
Acetylocholine
|
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 |
|
|
Erythrocytes
|
-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
|
|
|
Calcium
|
-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' |
