Dynamics Of Bone Growth

Question 1

Process by which bone forms, or by which tissue changes into the bone

Answer 1

Ossification

Question 2

Loosely organized undifferentiated mostly mesodermal cells that give ries to such structures as connective tissues, blood, lymphatics, bone and cartilage

Answer 2

Mesenchymal cells

Question 3

Cells responsible for the synthesis and mineralization of bone during both bone formation and bone remodeling

Answer 3

Osteoblasts

Question 4

An unmineralized organic tissue secreted by osteoblasts that eventually undergo calcification and is deposited as lamellae or layers in the bone matrix

Answer 4

Osteoid

Question 5

Cells in the cartilage that secrete extracellular matrix to form the cartilage model for bone

Answer 5

Chondrocytes

Question 6

Two types of bone ossification

Answer 6

Intramembranous and endochondral ossification

Question 7

This Ossification Involves the DIRECT conversion of mesenchyme to bone

Begins when the neural crest derived mesenchymal cells differentiate into specialized, bone-forming cells called osteoblasts

Answer 7

Intramembranous ossification

Question 8

This process involves the replacement of hyaline cartilage with bone

Answer 8

Endochondral ossifcation

Question 9

Primary ossification center forms in the diaphyseal region of the periosteum called the ___

Answer 9

Periosteal collar

Question 10

Secondary ossification centers develop in the epiphyseal region after ___

Answer 10

Birth

Question 11

Bones that are formed via intramembranous ossification

Answer 11

Flat bones of the face, cranial bones
Clavicles ( colarbone )

Question 12

Bones that are formed via endochondral ossification

Answer 12

Long bones of the axial skeleton ( vertebrae, ribs ) and the appendicular skeleton (limbs)
