Bone resorption is
building of the bone tissue by osteoclasts
building of the bone tissue by osteoblasts
breakdown of bone tissue by osteoblasts
breakdown of bone tissue by osteoclasts
The chondrocytes near the center of the shaft enlarge and then die forming the beginning of the medulary cavity.
Step 1 & 2
Step 3
Step 4
Step 5
Blood vessels enter the medulary cavity and cartilage starts to form bone.
Step 1 & 2
Step 5
Step 3
Step 4
The medullary cavity is completely formed, diaphysis enlongates and thickens, and the epiphysises start to ossify.
Step 5
Step 4
Step 3
Step 1 & 2
Epiphysises are completely ossified, cartilage is only left at the ends and epiphyseal plates.
Step 5
Step 3
Step 4
Step 1 & 2

bone collar
epiphyseal line
osteoporosis
Bone breaks incompletely, occurs most commonly during the infantile stages of life.

length
mass
width
weight
Mechanical stress increases the ____________ of bones. Walking, exercising, or traction stimulate this.
length

composition
flexibility
What is happening in this stage of bone healing?
Hematoma forms.
Hard callus forms, osteoblast cells create new bone
Remodeling, osteoclasts remove extra bone until its completely healed
Soft callus forms, forming fibrous material producing the initial "bridge" between the bones
What is happening in stage 1 of bone healing?
Hematoma forms bringing blood to the area to promote healing.
Hard callus forms, osteoblast cells create new bone
Remodeling, osteoclasts remove extra bone until its completely healed
Soft callus forms, forming fibrous material producing the initial "bridge" between the bones
What is happening in stage 3 of bone healing?
Hematoma forms bringing blood to the area to promote healing.
Hard callus forms, osteoblast cells create new bone
Remodeling, osteoclasts remove extra bone until its completely healed
Soft callus forms, forming fibrous material producing the initial "bridge" between the bones
What hormones stimulates bone destruction in response to low blood calcium levels
Calcitonin
Parathyroid hormone
Cortisol
Thyroid hormone
