Pd. 6 – Lab partners
Get together with your partner. Each pair needs
◦ Calculator◦ Chapter 13 packet◦ Worksheet (Activity 13-4/Activity 13-1)◦ Estimation of Body Size from Individual Bones:
Cross out “humerus” in DIRECTIONS (Questions section)
Turn to pg. 371 in packet, and take out your notes – we will do some examples!
Bones and Height
Skull Suture Marks◦ Coronal Suture – closes around age 50◦ Lamboidal Suture
Closing ~21 Accelerates closing ~26 Fully closed ~30
Age Determination
5 y. o. skull vs. 60 y. o. skull
Long Bones – Femur or Humerus ◦ Fused by ~20 – before this, cartilage at ends
Pelvis◦ Fused by ~30 – different areas start as separate
bones More detailed information in packet
Age Determination
Age in X-rays
Child’s Hand Adult Hand (~20 y. o.)
Turn over to Activity 13-1
Use the Chapter 13 packet to find further information.
