Ch 5 Lec 1 - Skeletal System Flashcards
how many bones
206
2 divisions of skeletal system
axial, appendicular
2 types of bone tissue
compact, spongy
dense smooth bone
compact
bone with open spaces within
spongy
skeleton makes up blank percent of body mass
20
four components of skeletal system
ligaments, tendons, bone, cartilage
three functions of skeletal system
support, movement, storage, blood cell production, protection
cartilage has a blank and blank
cells, extracellular matrix
these are found in compartments called lucunae in cartilage cells
chondrocytes
collagen and elastic fibers are in the blank
extracellular matrix
this is the ground substance of chondroitin sulfates
extracellular matrix
no arteries, veins, or lymphocytes in blank
cartilage
three types of cartilage
hyaline, elastic, fibrocartilage
cartilage heals blank
slowly
cartilage that is the most common but is the weakest
hyaline
structure of this cartilage is chondrocytes, chondroitin sulfate, some collage, water
hyaline
location of this cartilage is in the embryonic skeleton, articular surfaces, respiratory passages, nasal septum, between ribs and sternum
hyaline
structure of this flexible cartilage is in chondrocytes, intermediate amount of chondroitin sulfate, densely packed elastic fibers
elastic
location of this cartilage is in auricle, tip and lateral walls of nose, epiglottis
elastic
structure of this cartilage is chondroctyes, small amount of chondroitin sulfate, densely packed collagen fibers
fibrocartilage
very strong cartilage
fibrocartilage
location of this cartilage is in intervertebral disc, interpubic disc, articular cartilage in knee
fibrocartilage
