The Skeletal System: Unit 4

The Skeletal System: Unit 4

Author: Nate Holz
  • Identify the subdivisions of the skeleton as axial or appendicular
  • Be able to list the functions of the skeletal system
  • Name the four main classifications of bones
  • Identify the structure of bone
  • Describe the process of bone formation and bone remodeling
  • Be able to identify and name the bones and processes of the skull and other axial skeleton bones
  • Identify the parts of a typical vertebra and the regions of the vertebral column
  • Identify the appendicular skeleton and describe the difference between a male and female pelvis
  • Name the three major categories of joints and understand the movement of each

This is a big "scary" unit with a lot of information to understand. This lesson will look at the skeleton in general and then in more detail - our lab will have you learning the names of all bones and many of their markings. We will also look at joints, and injuries of bone; broken bones and diseases.

Unit 4 Class Day Log

  1. Friday (10/7): 2 Handouts: Anatomy of Bone (4-1.02)/Basic Skeleton Label (4-1.01) (both in packet) & Watched the movie, "Contagion."
  2. Monday (10/10): Notes: Intro to Skeleton
  3. Wednesday (10/12): Notes: Bone Markings. 3 Handouts: Formation, Growth & Repair, Types of Bone, Bone Terminology (all three in packet). Also watched Hank Green's video on the skel. system.
  4. Friday (10/14): Notes: The Skull, Lab: Skull. You will complete two papers that will be turned in to the packet; the skull lab (4-1.08) and a paper called Bones of the Skull (4-1.081) that has you label diagrams of the skull. I will also handout a checklist of all the bones and features you need to learn on the skull. This checklist does not have to be in your packet. You will also receive handout 4-1.07 which is a study guide for the skull.
  5. Monday (10/17): Notes on the Axial Skeleton. You will also receive 3 handouts - all three go in your packet. The handouts are: 4-1.09, 4-2.01 (both on the vertebral column), and axial skeleton lab 4-2.02.
  6. Wednesday (10/19): Notes on the Appendicular Skeleton. Another 3 handouts - A 3-page study guide (4-2.03) on the appendicular skeleton, a 2-page hand-out on the pectoral and pelvic girdle, (4-2.05) and a 2-page lab hand-out (4-2.04) entitled "The Appendicular Skeleton." Oh, one more called Medical Imaging - use the internet for this one.
  7. Friday (10/21):  A 3-page "Joints Homework" and a 1 page Joint Organizer were passed out - both go in the packet. Also watched Crash Course #20 on bones and joints, and finished the notes on the appendicular skeleton to be ready for next Wednesday's lab quiz.
  8. Monday (10/24): Completed the notes on Joints. Watched two video clips on surgery on the knee. No papers handed out.
  9. Wednesday (10/26): Video Clip on Bone Fractures and a quick look at my notes on fractures (see in Sophia.) Lab test on the skeletal system.
  10. Friday (10/28): Oral testing starts (finish Monday if needed) and the unit ends today. 
  11. Monday (10/31): Finished oral testing - finished the written on-line test. We start the muscle unit this Wednesday.

Unit 4 Assignments (The Skeletal System)

Check out your assignments here (note - some items may not be assigned but could still be good resources for your study of the skeletal system:

The Skeletal System: Part 1 (Overview to a discussion on bone formation)

A powerpoint that gives an introduction to the skeletal system. Topics discussed:
- functions of the bones
- division of the skeletal system (axial/appendicular)
- classification of bone by tissue type
- classification of bone by size
- a look at bone structure at both the gross and micro level
- bone growth and a look at Rickets

Crash Course Anatomy: The Skeletal System

Today Hank explains the skeletal system and why astronauts Scott Kelly and Mikhail Kornienko are out in space studying it. He talks about the anatomy of the skeletal system, including the flat, short, and irregular bones, and their individual arrangements of compact and spongy bone. He'll also cover the microanatomy of bones, particularly the osteons and their inner lamella. And finally he will introduce the process of bone remodeling, which is carried out by crews of osteocytes, osteoblasts, and osteoclasts.

Bone Markings: Part 2

Every bump, groove, and hole has a name on your bones...I borrowed this ppt from the web and it parallels page 142 in your textbook

The Skull: Part 3

Learn all the bones in the skull and their features; cranial and facial bones

Human skull - exploded skull with bones labelled, based on CT scanning

Human skull animation that yaws, rolls, and explodes into individual bones, which are labeled. The skull (OUVC 10503) was CT scanned at O'Bleness Memorial Hospital in Athens, Ohio. Ryan Ridgely segmented all of the bones in Amira and generated the movies in QuickTime. Jason Bourke did the labeling.

Making a Paper Mache Skeleton

Let's make a full size skeleton out of paper mache! I found the link below and created a ppt from it.

Part 6 - Joints

A ppt that looks at the bodies articulations or joints - where two or more different bones come together. We will look at both classifications of joints; by function and by structure.

Crash Course Anatomy: The Joints

We continue our look at your bones and skeletal system, skipping over the silly kid's song in favor of a more detailed look at your your axial and appendicular skeleton. This episode also talks about the structural and functional classifications of your joints and the major types of body movement that they facilitate.

Why Do Joints Pop and Crack?

SciShow explains what really causes those popping sounds your joints make -- fluid dynamics, people! -- and what you should watch out for if you're a habitual knuckle-popper.

Part 7 - Bone Fractures & Diseases of Bone

A ppt that looks at the various fractures or broken bones that can effect the skeleton, as well as some diseases that affect this system. We also look at some slides from the "Visible Human Project."
