• The smallest is the stirrup bone in the ear which can measure 1/10 of an inch.

Your face has 14 bones.

One fourth of your bones are located in your feet .

1.
Describe the functions of the skeleton.
• Gives body shape & support

• Protects internal organs

• Attaches to muscles to help bones move

• Produces blood cells

• Stores calcium and phosphorus

2. Which life process does the skeletal system help carry out?
• LOCOMOTION

3.
Describe the two types of bone marrow.

• Yellow marrow = fat cells

• Red marrow = produces blood cells

4. Identify the systems that regulate locomotion.
• Nervous and endocrine systems

5. Describe the function of ligaments.
• Tough band of tissue that holds bones together

6. Describe the function of tendons.
• Tough band of tissue that connects muscles to bones

7.
Describe 4 characteristics of cartilage.
• Smooth and slippery
• Flexible

• Acts as a shock absorber

• Makes movement easier by reducing friction that would be caused by bones rubbing together

• Does not contain blood vessels
Nutrients delivered by nearby blood vessels

• Give shape to certain body parts (ears, nose)

• Skeleton of newborn made mostly of cartilage

8. Identify some locations of cartilage in your body.

• In between vertebrae

• At ends of bones

• In joints

TOPIC: Locomotion
Aim: Explain the structure and functions of the 3 types of muscles.
Do Now: Take out endocrine system ISN and skeletal system notes.
HW: Ditto – Nervous System Review
CL Nervous and Endocrine Systems due
Thursday

1. Identify each labeled gland in the diagram. Leave space under each gland.
2. Under each gland, write the hormone(s) released and the function of the hormone(s).
3. In a complete sentence, identify how hormones are transported throughout the body.
4. In a complete sentence, identify the types of cells that are affected by hormones.
5. In a complete sentence, identify the proteins that hormones attach to on these types of cells.

8. Identify some locations of cartilage in your body.

• In between vertebrae

• At ends of bones

• In joints

Scapula (shoulder blades)

Sternum = breast bone

Vertebrae = backbone
(spinal column)

Scoliosis

Humerus = upper arm bone
Ulna & radius = lower arm

Femur = thigh bone (longest & strongest)

Carpals = wrist bones
Metacarpals = hand bones

Phalanges = fingers & toes

Did You Know?
Humans and giraffes have the same number of bones in their necks? A
Giraffe ’ s neck vertebrae are just much, much longer!

The only bone not broken so far during any ski accident is one located in your inner ear.

If you break your wrist as an adult it will take you 8 weeks to heal.
A five year old child who breaks their wrist only takes 3 weeks to heal.

Babies are born without the patella (knee bone) it develops between ages 2 and 5.

Let ’ s summarize…
1. Identify structures that make up your skeletal system.
2. Identify the functions of your skeletal system.
3. Describe the difference between tendons and ligaments.
4. Explain the function of cartilage.
5. Where is cartilage found?
