irregular connective tissue that surounds cartilage is called ________
the perichonfrium, it resists outward expansion
The perichondrium brings ____________ that bring the nutrients to the cartilage
What are the three types of cartilage and where are they found
Hyaline - covers the end of long bones, ribs, larynx, nose
Elastic - external ear and epiglotis
Fibrocartilage - menisci of the knee and invertebral discs
What are the two ways collagen grows?
Describe appositional cartilage growth
cells in the ichondrium secrete matrix against the external face of existing cartilage
Explain interstitial cartilage growth
Lacunae-bound chondrocytes inside the cartilage divide and secrete new matrix, expanding the cartilage from within
Calcification of cartilage occurs during
normal bone growth in young people and old age

Appendecular skeleton-bones of the upp and lower limbs, shoulder and hip

Support-form the framework that supports te body and cradles soft tissue
Protection-provides a protective case for the brain, spinal cord and vital organs
Movement-provide levers for muscles
Mineral Storage-resevoir for minerals, especially calcium and phosphorus
Blood cell formation-hematopoisis occurs within the marrow cavities and bones
Osteogenesis and ossification is
the process of bone formation
Intramembranous ossification is when
bone developes from a fibrous membrane
When bone forms by replacing hyaline cartilage it is called
The formation of most of the flat bones/frontal, parietal and occipital is called
What are the stages of intramembranous ossification?
An ossification center appears in the fibrous connective tissue membrane
Bone matrix is secreted within thhe fibrous membrane
Woven bone and perioseum form
Bone collar of compact bone form and red marrow appear
