Intro to anatomy Flashcards
1
Q
What is Anatomy?
A
- study of internal and external body structures
- relationships between structures (eg. bone and muscle)
2
Q
Subdivisions of Anatomy
A
- Gross Anatomy
2. microanatomy
3
Q
Gross Anatomy
A
- visible to the eye
eg. bones
4
Q
Microanatomy
A
microscope required
- cytology
- histology
5
Q
Cytology
A
the study of internal structures of individual cells
6
Q
histology
A
study of tissues
7
Q
tissues
A
groups of cells
8
Q
levels of organization
simple to complex
A
- chemical level
- cellular level
- tissue level
- organ level
- organ system level
- organism (top of hierarchy)
(this is a hierarchy-each level contains those below)
9
Q
chemical level
A
basic level
- atoms
- atoms join to form molecules
10
Q
cellular level
A
-molecules form organelles which form cells
11
Q
cell
A
basic unit of structure and function
- all cells contain chemicals but their functions may differ
eg. red blood cells (rbc), neurons, muscle cells
12
Q
tissue level
A
a group of structurally similar cells with a common function
-there are four major types
13
Q
four major types of tissues
A
- epithelial
- connective tissues
- muscles
- nervous
14
Q
organ level
A
- 2 or more tissues working together for a common function
eg. stomach- all four major tissues
- function = digestion
15
Q
organ system level
A
several related organs that work together to accomplish a common purpose
eg. respiratory system
- lungs, trachea, etc.
- function = respiration
