What is regional anatomy?

Answer 4

Structures in a particular region of the body are examined at the same time (muscles, bones, blood vessels, and nerves)

Question 5

What is systemic anatomy?

Answer 5

Body structures that are studied system by system.

Question 6

What is surface anatomy?

Answer 6

The study of internal structures as they relate to the overlying skin surface (ex: identifying bulging muscles underneath a body builder’s skin)

Question 7

What is microscopic anatomy?

Answer 7

Structures that are too small to be seen with the naked eye

Question 8

Name two subdivisions of microscopic anatomy.

Answer 8

1) Cytology- cells of the body

Question 9

What is developmental anatomy?

Answer 9

It traces structural changes that occur throughout the life span

Question 10

Name a subdivision of developmental anatomy.

Answer 10

Embryology- concerns developmental changes that occur before birth

Question 11

True or False. Anatomical terminology is used so that people can name its parts and describe how they are related so that other people will have no trouble understanding you.

Answer 11

True

Question 12

What are the 3 subdivisions of physiology? Describe what each subdivision does.

Answer 12

1) Renal Physiology: concerns kidney function and urine production
2) Neurophysiology: explains the workings of the nervous system
3) Cardiovascular Physiology: examines the operation of the heart and blood vessels

Question 13

True or False. Physiology often focuses on events at the cellular or molecular level.

Answer 13

True

Answer 24

True

Question 25

Name the 2 subdivisions of movement.

Answer 25

1) Skeletal System

Answer 27

Digestion

Question 28

What are chemical reactions that occur within the body cells called? (Hint: “it is a state of change”)

Answer 28

Metabolism

Question 29

What is the difference between catabolism and anabolism?

Answer 29

Catabolism- breaks down substances into simpler building blocks
Anabolism- synthesizes more complex substances from simpler building blocks

Question 30

What is the process of removing wastes from the body called?

Answer 30

Excretion

Question 31

What levels do reproduction occur at?

Answer 31

Cellular and Organismal Level

Question 32

True or False. Growth is a decrease in the size of a body part of organism as a whole

Answer 32

False.
Growth is an INCREASE in the size of a body part or organism as a whole

Question 33

What is the ultimate goal of the body systems?

Answer 33

To maintain life via survival needs

Question 34
