- synovial joints
- reinforcement of the respiratory tract
articular cartilage lacks a ____________-
perichondrium
hyaline cartilage from the trachea includes a fibrous ____________
perichondrium
def: intermediate between dense regular CT and hyaline cartilage, conferring both tensile strength and resistance to compression
