1. Skeletal System Objectives:
Recognize the interdependence of major systems of an animal’s body;
Describe types of bones and connective tissue along with their function
Classify types of joints in a skeleton
Label bones on a skeleton diagram

2. OBJECTIVE A- Recognize the interdependencies of major systems of an animal’s body
What makes a car run?

3. there are several systems.
OBJECTIVE A- Recognize the interdependencies of major systems of an animal’s body
The secret is…
there are several systems.
If one system fails, the automobile will not function properly or may not function at all. Animals are much like cars in that they are composed of a variety of interdependent systems.

4. What does interdependent mean?
OBJECTIVE A- Recognize the interdependencies of major systems of an animal’s body
What does interdependent mean?
Systems that mutually depend
on each other to work.

5. Why or Why Not? Can only one system function on it’s own?
OBJECTIVE A- Recognize the interdependencies of major systems of an animal’s body
Can only one system function on it’s own?
Why or Why Not?

6. What is the purpose of a skeletal system???
OBJECTIVE B-Describe types of bones and connective tissue along with their function
The Skeletal System
Provides the frame and support for all the other systems and organs.
This system is made up of cartilage, bones, and connective tissue.
What is the purpose of a skeletal system???

7. OBJECTIVE B-Describe types of bones and connective tissue along with their function
Cartilage
is composed of firm tissue that is not as hard as bone and is somewhat flexible.
EXAMPLES: Nose & Ears

8. Long Bones Are the longest bones
OBJECTIVE B-Describe types of bones and connective tissue along with their function
Long Bones
Are the longest bones
Provide support for the body giving it the rigidity (hardness) necessary to stand and move.
EXAMPLES:
Leg Bones

11. Where are short bones located?
OBJECTIVE B-Describe types of bones and connective tissue along with their function
Where are short bones located?

12. Short Bones Are mostly found in the joints and serve as hinges.
OBJECTIVE B-Describe types of bones and connective tissue along with their function
Short Bones
Are mostly found in the joints and serve as hinges.
They help cushion shock and protect long bones by being flexible
Are often as big around as they are long
EXAMPLES: ankles

13. What is an example of an irregular bone?
OBJECTIVE B-Describe types of bones and connective tissue along with their function
What is an example
of an irregular bone?

14. Irregular Bones Function as support and protection
OBJECTIVE B-Describe types of bones and connective tissue along with their function
Irregular Bones
Function as support and protection
Are irregularly shaped.
EXAMPLE: Vertebrae
These bones make up the backbone, which is not a single bone, but a series of irregular bones. They flex and bend to give the animal movement. The vertebrae are divided into several different areas: Cervical, Thoracic, Lumbar, Sacral, and Coccygeal

15. OBJECTIVE B-Describe types of bones and connective tissue along with their function
Cervical Vertebrae-The section in the neck from the skull to the first rib.
Thoracic-extends along the rib cage. Each of these has a rib attached to each side.
For Your Information: Cattle have 13, Horses have 18, and Pigs have dependent on breed.

16. OBJECTIVE B-Describe types of bones and connective tissue along with their function
Lumbar-The area of the spinal column from the last rib to the pelvis. Also referred to as the loin.
For Your Information: If you have ever judged sheep, you may have measured this region with your hand. Animals with a long lumbar region are desirable, as this is where some of the most valuable cuts of meat come from.

17. OBJECTIVE B-Describe types of bones and connective tissue along with their function
Sacral-Extends through the pelvic area. The bones in this region are fused together to form a rigid section called the sacrum- providing an attachment for the pelvis.
Coccygeal- The vertebrae that continue from the pelvis to the end of the tail.
For Your Information: The bones at the top of the tail are larger than the bones at the end. The size tapers until the ones at the end have no channel.

18. are relatively thin and flat They usually help to protect organs
OBJECTIVE B-Describe types of bones and connective tissue along with their function
Flat Bones:
are relatively thin and flat
They usually help to protect organs
Usually multiple bones fused together
EXAMPLE
Skull- is composed of flat bones.
These bones encase the brain and protect it.
Pelvis-

19. On the Cow Skeleton, color the following:
OBJECTIVE B-Describe types of bones and connective tissue along with their function
On the Cow Skeleton, color the following:
Red- Long bones
Green- Short bones
Grey- Flat Bones
Irregular Bones:
Purple- Cervical
Pink- Thoracic
Blue- Lumbar
Orange- Sacral
Yellow- Coccygeal

21. OBJECTIVE C-Classify types of joints in a skeleton
How are joints classified?

22. OBJECTIVE C-Classify types of joints in a skeleton
Joints are connections of bone in the animal’s body to make up the skeletal system.
The connections are held together by bands of tough tissue called ligaments that bind the bone to the joints. Ligaments give the joints flexibility and serve as shock absorbers to protect the ends of bones.
They are classified by the way they move…

23. OBJECTIVE C-Classify types of joints in a skeleton
Classifications of Joints:
Gliding
Hinge
Ball & Socket
Joint Video Clip

24. OBJECTIVE C-Classify types of joints in a skeleton
On the Horse Skeleton,
draw a shape around the following joints:
Triangle- Hinge joint
Circle- Ball & Socket joint
Square- Gliding

26. OBJECTIVE C- Label bones on a skeleton diagram

27. OBJECTIVE C- Label bones on a skeleton diagram

28. OBJECTIVE C- Label bones on a skeleton diagram
