describe Hyaline cartilage

Answer 1

is slippery and strong when compressed, but has little tensile strength (strength against being stretched)

Question 2

Fibrocartilage

Answer 2

tough and strong both when compressed and when stretched (high tensile strength)

Question 3

what is seen in the epiphyseal plates

Answer 3

temporary Cartilaginous Joints - Synchondroses
flexibly joining the epiphysis to the diaphysis of growing long bone.
made of hyaline cartilage that is eventually replaced by bone after growth is completed
