AND CORRECT ANSWERS (VERIFIED
ANSWERS) |AGRADE
3 types of Cartilage - Answers -✔✔ hyaline, elastic, fibrocartilage
hyaline cartilage - Answers -✔✔ most abundant cartilage
bone started as __________, so the __________ at the end of bones just never turned
into bone` - Answers -✔✔ hyaline cartilage, hyaline cartilage
Examples of hyaline cartilage - Answers -✔✔ larynx, rings of the trachea, end of the
nose
elastic cartilage examples - Answers -✔✔ external ears and epiglottis
fibrocartilage examples - Answers -✔✔ vertebral discs, menisci in the knee
appositional growth - Answers -✔✔ growth of cartilage is due to the perichondrium
secreting new matrix - leads to more ground substance and fibers - leads to more
cartilage being made
intersitial growth - Answers -✔✔ chondrocytes within the matrix of the cartilage divide -
these chondrocytes are matured fibroblasts - cells are actively dividing, so more cells -
more cartilage
skeletal divisions - Answers -✔✔ axial and appendicular
Axial Skeleton - Answers -✔✔ skull, ribs, and vertebral column
Main job of Axial Skeleton - Answers -✔✔ protection from trauma and support of the
appendicular skeleton
appendicular skeleton - Answers -✔✔ Bones of the upper and lower limbs and the
pectoral and pelvic girdles
Major function of Appendicular Skeleton - Answers -✔✔ locomotion
Classifications of bones - Answers -✔✔ long, short, sesamoid, flat, irregular
, long bones - Answers -✔✔ longer than wide, all bones of the limbs except for carpals
and tarsals and patellar
short bone - Answers -✔✔ wider than long, carpals and tarsals , sesamoid bone (short
bone that grows in tendon) ex. patella
sesamoid bone - Answers -✔✔ bones that are embedded within a muscle or tendon,
ex. patella
flat bones - Answers -✔✔ flat, ex. ribs and shoulder blades
irregular bones - Answers -✔✔ does not fit into the other categories, ex: vertebrae and
pelvis bones
long bone structure made up of - Answers -✔✔ diaphysis, medullary cavity,. epiphyses,

bone on the outside
membranes of long bone - Answers -✔✔ periosteum and endosteum
periosteum membrane (long bone) - Answers -✔✔ comes from periochondrium,
surrounds the outer portion of the bone, dense irregular connective tissue
