histology Flashcards
-under the skin (hypodermis), and around organs (fascia)
-function: moveable connection between structures
-cell type: fibroblast
areolar conn tiss
-under skin, around organs
-function: store energy, warmth, cushion
-cell type: adipocytes
adipose
-in tendons and ligaments
-function: resist tension in 1 direction
-cell type: fibroblast
dense regular
-less organized and uniform
-nuclei are stretch long and tissue is wavy
-multiple direction tension
-found in dermis, digestive tract, fibrous capsule organs/joints
dense irregular
-joints, nose, located between joints
-function: smooth surface for joint movts and resilience
-cell type: chondrocytes in lacuna
hyaline cart
-in ear lobe, epiglottis
-function: flexible but maintains shape
-cell type: chondrocytes in lacuna
elastic cart
-in intervertebral discs, meniscus
-function: shock absorber
-cell type: chondrocytes in lacuna
fibrocartilage
“floating donuts”
-look for red/white blood cells
blood
“dark hairy eyes”
-look for chondrocytes inside lacuna with dark elastic fibers
-lacuna is tight together
elastic cart
“ghost eyes”
-look for glassy, smooth matrix with scattered chondrocytes in lacuna
-no visible fibers
hyaline cart
“wavy water with eyes”
“ramen noodles”
-look for thick, wavy collagen fibers with small chondrocytes in lacuna
-scattered lacuna
fibrocartilage
“smooth waves”
look for parallel and wavy collagen fibers (all in same direction) with flat nuclei
dense regular
“messy swirl”
“hamburger meat”
-look for collagen fibers in all directions giving swirled appearance
dense irregular
“spider web”
-look for loose network of fibers with lots of open space
areolar
“big bubble wrap”
-look for large empty looking fat cells with nucleus pushed to edge
adipose
