Do Now 01/28-29•Which bone is inferior the saccrum?

•Which bone groups are medial the ribs (I can think of two possible responses)?

•What is the term for the long shaft of the bone?

•What are the long bones of the feet called?•What is the term for the bone group composed of flat bones in the skull?

Daily ObjectiveKnowledge:O Types of bone fractureO What happens when a bone breaks.O Stages of bone healing Skills:O Ability to identify types of fracture and possible

causes.O Ability to explain the steps in bone healing and

relate them to bone growth and the parts of the bone.

Big IdeaO Broken bones are one of the most

common problems that doctors have to deal with. Understanding the process of how bones heal and what doctors do to assist will be helpful information for any student going into the medical profession.

Bone FracturesO A fracture is a break in the bone, caused by

spontaneous trauma or pathology.O Classified by nature of the break:

O GreenstickO FissuredO ComminutedO TransverseO ObliqueO Spiral

You have 10 minutes to use page 136 to explain these fractures.

Healing a Broken Bone

Bone healing process:O 1) A hematoma (definition) forms preventing

_________________________. Inflammation brings nutrients and antibodies to the site. (Which system is in charge of this transportation?)

O 2) The Periosteum is repaired first. The hematoma is converted into spongy bone close to the blood vessels by osteoblasts. The hematoma is converted to fibrocartilage by fibroblasts on the more superficial parts of the bone. (Think Spider Man)

O 3) The fibrocartilage is replaced with spongy bone (same as when the bone was growing).

O 4) The spongy bone is replaced with compact bone, the marrow is restored.

Check for understanding

OWhat is the periosteum?

OWhat is the function of marrow?

After osteoblasts build up new bone tissue the bone must then be remodled.

OWhich cells remove excess bony tissue?

Practice this knowledge

OTake a piece of paper and divide it into four regions.

O In each region, they will draw a representation of a step in the healing of a bone.

OThis can be a diagram, a comic, or any other visual way of representing the information for that step.

Do Now: 01/30-31

OProvide two reasons for a bone to fracture.

OWhat is the first part of the bone to heal during bone repair?

OHow long does it take a bone to heal?
