Human Body Worksheet

1. Explain the difference between anatomy and physiology.

Anatomy- The study of the structures that make up the human body.

Physiology- The study of the functions of the structures that make up the human body.

2. Please organize the following structures in order from smallest to largest: system, tissue, organ, and cell.

Cell, tissue, organ, and system

3. In the term physiology the suffix -logy means what?

The suffix -logy means "the study of".

4. What is the type of membrane that lines all of the passages leading the exterior?

Epithelial membrane

5. What do you call a mass of cells that all perform the same function?

It is called an organ.

6. What type of tissue is specialized for the conduction of nerve impulses?

Nervous tissue

7. The term epidermis contains a prefix and a root term. What is the root in this word and what does it mean? What is the prefix in this word and what does it mean?

Epi- is a prefix that means "upon" and dermis is a root which means "skin".

8. The term cavity appears frequently in this lesson. What does it mean?

It means "any hole or hollow area". This word is usually used for parts of the body such as the Thoracic cavity of like a cavity in a tooth.

9. Name the four main types of tissue and describe their function.

Epithelial- covers the body
Connective- supports and protects teh strucure(s) of the body
Muscle- specialized for contraction/movement
Nerve- specialized for the conduction of neural impulses

10. A cell is made of cytoplasm except for the nucleus which is made of protoplasm.


11. What type of membrane lines joint cavities and outer surfaces of bones?

Fibrous tissue

12. What is an organ system?

An organ system is the most complex organization of cells before and organism. it is composed of many different functioning groups of specialized cells that work together.

13. Name the five types of membranes and where each is located.

Cutaneous- it is the skin and anywhere to protect the body
Mucous- lines all the passageways that lead to the exterior of body
Secous- lines closed cavities and organs inside the body
Fibrous- lines all joint cavities and covers outer surface of bones
Fascia:

• Superficial- thin and tough membrane that covers muscles and lies right beneath the dermis
• Deep- much denser than superficial. covers glands, blood vessels and nerves. lies right below superficial

14. What is the function of the cell membrane? The nucleus?

Cell Membrane- regulates what enters and exits the cell. protects the cell and gives it a shape
Nucleus- controls all the actions of the cell

15. The cutaneous membrane is made of two distinct layers. Name each of these layers and describe what they are made of.

Epithelial- is made of many layers of cells which originate from a growth layer and move upwards from there. they die once they get too far from the growth layer.

Connective- (NovaNet did not have the asnwer to this question)
