Bone development

Question 1

intramembranous ossification

Answer 1

takes place at embryonic connective tissue membrane–mesenchyme–>condenses around brain and forms bone

Question 2

intramembranous ossification forms what bones

Answer 2

skull bones, mandible, diaphysis of clavicle

Question 3

T/F: when remodeled, intramemrbanous bone indistinguishable from endochondral

Answer 3

true

Question 4

centers of ossifcation

Answer 4

locations in embryonic membrane where ossification begin

Question 5

fontanels

Answer 5

unossified–large membrane covered spaces in developing skull bones
usually close by age 2

Question 6

endochondral ossification

Answer 6

bones ossified by hyaline cartilage model
cartilage formation begins and end of fourth week of development
some at end of 8th week
some not until 18-20 years old

Question 7

bones formed by endochondral ossification

Answer 7

base of skull, parts of mandible, epiphysis of clavicle, most of remaining bones of skeletal system
