Chapter 6 pt. 2 Flashcards
ossification (osteogenesis)
the process of bone tissue formation
endochondral ossification
- makes cartilage that is then replaced by bone
- long bones made this way
intramembranous ossification
- make fibers that then produce bones
- skull and clavicles
mesenchymal cells
cells that help form fibrous connective tissues that are used during intramembranous ossification to form the skull and clavicles
bones increase thickness by…..
appositional growth
T or F: hematopoiesis refers to the formation of blood cells within the red marrow cavities of certain bones
true
T or F: short, irregular, and flat bones all consist of thin plates of spongy bone covered by compact bone
True
T or F: the periosteum is a tissue that only serves to protect the bone because bones not supplied with nerves or blood vessels
False
T or F: the term osteoid refers to the organic part of compact bone matrix without calcium mineralization
True
T or F: closure of the epiphyseal plate stops all bone growth for the rest of life
False
Yellow bone marrow contains a large percentage of ——

osteoblast
What tissue kind is the forerunner of making long bones in an embryo?
hyaline cartilage
A fracture in the shaft of a bone would be a break in the ——-
diaphysis
Ossification of the ends/epiphyses of long bones—–
is produced by secondary ossification centers
