Flashcards in Topic 1: Introduction to Anatomy Deck (17):
1

What is Anatomy?

-Study of internal & external body structures
-Relationships between structures
example: bone + muscle

2

What is Gross Anatomy

visible to the naked eye

example: heart, lungs, kidney, bones

3

What is microscopic anatomy?

-Deals with structures too small to be seen with the naked eye

4

What are the subdivisions of microanatomy?

Cytology and Histology

5

What is Cytology?

Study of the internal structures of individual cells

6

What is Histology?

Study of tissues (groups of cells)

7

What are the levels of organization? (simple to complex)

1. Chemical
2. Cellular
3. Tissue
4. Organ
5. Organ system
6. Organism

8

What is the chemical level?

atoms
e.g. H + O atoms

atoms form to join molecules
example: water

9

What is the cellular level?

-Molecules form organelles which form cells

-Cells are the smallest unit of living things

-All cells contain chemicals but their functions may differ
example: red blood cells, neurons, muscle cells

10

What is the tissue level?

-Groups of similar cells that have a common function.

-There are 4 major types

11

What are the 4 major types of tissue levels?

CMEN

Connective Tissue
Muscle
Epithelium
Nervous system

12

What is the Organ level?

2 or more tissues working together for a common function

-e.g. stomach
- all 4 major tissue types
- function = digestion

13

What is the organ system level?

Organs that work together to accomplish a common purpose

e.g.
respiratory system
- lungs, trachea, etc
function = respiration

14

What is the Organism level?

all systems function together together to maintain life!

15

Which organ system includes the bones and cartilages?

The skeletal system

16

Which organ system includes the nasal cavity, lungs, and trachea?

Respiratory system organs

17

basic unit of structure and function

cell
