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
