  • In a newborn

there are 300!!!!!

How many bones are there?
  • In an adult, that are 206!!!
  • That is almost 100 fewer than infants. What happened?

All About Bones

do now1
DO NOW
  • Can you name any skeletal disorders?
  • What do you know about them?
  • What would you like to know?
activity
Activity
  • Create a foldable (like the one we did for the organ systems) that details the different types of fractures.
  • Name the fracture
  • Give the definition of the fracture
  • Draw it
  • Classify the difficulty to heal (how do bones heal, what process?)
  • There are 9 different fractures

  • Which fracture do you think are the hardest to mend? Why?
  • Which fracture do you think are the easiest to mend? Why?
males vs females

Males vs. Females

All About Bones

do now2
DO NOW
  • How can you distinguish between males and females?
  • Don’t just make a list, describe the differences.
activity1
Activity
  • You are a world-renowned bone expert.
  • You just received an urgent call from your Supervisor. He has informed you that a jogger has discovered a body in the woods. The body is nearly decayed and the police need to know if the victim is male or female.
some clues
Some clues
  • There are distinct difference in the bones that distinguish males from females
the pelvis
The Pelvis
  • Female Pelvic bones
    • Broader sciatic notch
    • Raised auricular surface
  • Males Pelvic Bones
    • Narrower sciatic notch
    • Flat auricular surface
skull1
Skull
  • Male skulls
    • Larger than females
    • Larger brow ridge
      • Sloping, less rounded forehead
    • Larger projections behind ears
    • Square chin
    • Greater definition of muscle attachment areas on the back of the head
skull2
Skull
  • Female
    • Smoother bone surfaces where muscles attach
    • Less pronounced brow ridges
      • More vertical forehead
    • Sharp upper margins of the eyes orbits
    • Smaller projections behind the ears
    • Chin more pointed
      • Larger, obtuse angle of the jaw
checklist for examining the skull
Checklist for examining the skull
  • For each category, describe what you see and determine male or female for that feature.
  • Brow ridge
  • Neck muscle attachments
  • Mastoid Process
  • Upper eye orbit margin
  • Angle of jaw
  • Chin
  • From there you can make a better estimate as to the sex.

  • What is the easiest way to determine the gender (using the skeleton) of an individual, and why?
off you go
Off you go!!
  • Work in small groups to determine the sex of the skeleton.
  • Turn in work individually!
do now3
Do Now
  • Which bones do you think would be the best for determining the height of an individual. Defend your answer.
  • You must pick one bone.
determining height from bone length
Determining Height from Bone Length
  • It is possible to determine the height of an individual based on the length of one bone.
  • This is useful because sometimes all that police recover is a few bones.
activity2
Activity
  • In this activity you will look at the bones in the arm.
    • Which are?
  • And the bones in the leg.
    • Which are?
activity3
Activity
  • Break into groups of 4.
    • 2 of you will measure the arm bones
    • 2 of you will measure the leg bones
    • Then compare your results
  • How accurate are you to the actual height of the person?
  • Which equation is more accurate?
important equations arms
Important Equations: Arms
  • Males
    • Height = (length of radius x 3.3) + 34
    • Height = (length of humerus x 2.9) + 27.8
  • Females
    • Height = (length of radius x 3.3) + 32
    • Height = (length of humerus x 2.8) + 28.1
important equations legs
Important Equations: Legs
  • Males
    • Height = 2.42 x (tibia length in cm) + 81.93
  • Female
    • Height = 2.90 x (tibia length in cm) + 61.53
  • Using the femur and tibia
    • Height = 1.31 x (length of femur in cm + length of tibia in cm) + 63.05

  • In some cases all that a forensics team has to go on is a bone.
  • What are your conclusions regarding the level of accuracy you can obtain in predicting height based on one or two bones?
