Lesson 5 Process of Ossification Flashcards
is a bone-forming cell that has become entrapped within the bone matrix
Osteocyte
multipotent stromal cells that can differentiate into a variety of cell types, including.
Mesenchymal stem cells
are thin columns and plates of bone that create a spongy structure in a cancellous bone, which is located at the ends of long bones and in the pelvis, ribs, skull, and vertebrae
Trabeculae
an unmineralized organic tissue that eventually undergoes calcification and is deposited as layers in the bone matrix
Osteoid
large cell responsible for the synthesis and mineralization of bone during both initial bone formation and later bone remodeling.
Osteoblast
is a type of bone cell that breaks down bone tissue. This is critical in the repair, maintenance and remodeling of the bones of the vertebral skeleton
Osteoclast
cells that produce and maintain cartilaginous matrix, which consists mainly of collagen and proteoglycans
Chondrocytes
a group of mesenchymal cells within a highly vascularized area of the embryonic connective tissue proliferates and differentiates directly into pre-osteoblasts and then into osteoblasts.
intramembranous ossification
can be broken into a series of stages
Endochondral ossification
fuse after puberty, preventing continued growth
epiphyseal growth plates
the process of bone formation
Ossification or osteogenesis
consists of the skeletal, cardiac and smooth muscle tissues. It allows mobility; provides stability of joints; keep the body’s posture; facilitate circulation, breathing or respiration, digestion, urination, child birth, and vision. It also provides organ protection and temperature regulation.
Muscular system
is composed of the bones and cartilages. It supports the body; facilitate movements, protects organs, produce blood cells and stores and releases minerals and fats.
skeletal system
The human body has how many muscles?
620 muscles
The human body has how many bones for adults?
206 bones
