tissue.

I. The Skeletal SystemA. List and define the 2 types of bone

tissue.1. Compact bone: 2. Spongy bone:

I. The Skeletal SystemA. List and define the 2 types of bone

tissue.1. Compact bone: functions as supportive tissue.2. Spongy bone: less dense calcium network

I. The Skeletal SystemB. Where are the 2 types of bone

tissue found?1. Compact bone: outside most bones.2. Spongy bone: inside bones, ends of long bones, most

short bones.

I. The Skeletal SystemC. Define cartilage and its purpose.• flexible connective tissue found in

many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs.

• Cartilage acts as a cushion between the bones.

I. The Skeletal SystemD. Define ligaments and their

purpose.• fibrous tissue that connects bones

to other bones• Ligaments hold the bones of many

joints together.

II. The SkeletonA. Color and label

the axial skeleton and appendicular skeleton

B. Define the axial skeleton and give examples of bones from this section

C. Define the appendicular skeleton and give examples of bones from this section.

II. The SkeletonB. Define the axial skeleton : Provides structure and protects

some organs. EX: Skull, ribs, spinal column, pelvisC. Define the appendicular skeleton: allows movement. EX: Shoulder, arms, legs.

D. List the 4 changes the skeleton makes.

1. Infancy2. Childhood3. Adolescence4. Adulthood

E. Describe what happens at each stage.

1. Infancy: spaces between bones in skull close.

2. Childhood: growth occurs at bone plates

3. Adolescence: at end of adolescence, bones stop growing.

4. Adulthood: old bone broken down and new bone formed

F. Joints of the Human BodyOpen Sciencesaurus to 086 and

complete the chart.Joint Type Where

FoundMovement Example

The Muscular Systemhttp://kidshealth.org/PageManager.jsp?lic=1&article_set=54040&cat_id=20607

I. The Muscular SystemA. List the 3 functions that muscles

perform.1. Movement2. Maintaining body temperature3. Maintaining posture

I. The Muscular SystemB. Define homeostasis.Process that organism maintains

internal conditions needed for health and functioning.

I. The Muscular SystemC. Why is homeostasis important?Because we need to maintain the

correct body temperature

I. The Muscular SystemOpen Sciencesaurus to 087 and

answer D, E, F, and G.D. List the 3 types of muscles and

where each type of muscle is found.

E. Which muscle is voluntary and which muscle is involuntary?

F. What attaches skeletal muscles to bone?

G. How do muscles produce movement?

I. The Muscular SystemD. List the 3 types of muscles and

where each type of muscle is found. 1. Skeletal muscles: attached to

bones2. Smooth muscles: found inside

some organs.3. Cardiac muscle: heart

I. The Muscular SystemE. Which muscle is voluntary and

which muscle is involuntary?1. Voluntary: skeletal.2. Involuntary: smooth and cardiac.

I. The Muscular SystemF. What attaches skeletal muscles to

bone?– tendons

G. How do muscles produce movement?– Skeletal muscles act in pairs.

When one contracts, the other relaxes, and vice versa.

I. The Muscular SystemH. What do skeletal muscles have to

do as infants and adolescences grow?– Develop and strengthen.

I. What is the relationship between exercise and muscles?– When you exercise regularly,

your muscles get bigger.
