Week 1: Boney Pelvis Flashcards
Bone develop from what process?
Ossification
What is the definition of ossification
The process which typically involves the formation of bone tissue in either dense connective tissue or cartilaginous tissue
What are the two types of ossification
Intramembranous ossification and intracartilaginous ossification
Where does intramembranous ossification occur?
Connective tissue membrane
Where does intracartilaginous ossification occur
Hyaline cartilage
What ossification type do all the bones of the lower limb and pelvis develop from?
Intracartilaginous ossification
What are the long bones of the lower limb?
Femur, tibia, fibula, metatarsal bones and phalanges
What are the short bones of the lower limb?
Tarsal bones and Patella
What are the irregular bones of the lower limbs
Hip bone, and the sacrum
What is apposition all growth?
Thickness/thickening of the bone
What is longitudinal growth?
Length of the bone
Where does longitudinal growth occur in the long bones?
Epiphyseal plate
Where does appositional growth occur on a long bone
Periosteum
In long bones - Primary of ossification centre is?
Centre zone of bone tissue that develops with the diaphyisi/shaft of the long bone model of cartilaginous tissue
What is the secondary oss centre in long bones?
The zone of bone tissue that is located in the epiphysis of the developing bone
When does primary oss occur in long bones?
Occurs before birth in ALL long bones of the lower limb
How many secondary centres do the metatarsals and phalanges have per bone
One centre
How many secondary centres do the tibia and fibula have
Two centres per bone
How many secondary centres does the femur have
Multiple centres per bone
