Microscopic
- cytology: study of cells
- histology: study of tissues
Gross
- developmental: changes from conception to birth
- embryology: changes prior to birth
- surface: study of internal structures as they relate to the overlying skin surface
- regional: study of the relationship of all structures in a particular region
- systemic: gross anatomy of each organ system
Describe anatomical position. - Answers - Erect
- Face/ Palms/ Feet forward
- Upper limbs at side
- Lower Limbs parallel
Anatomical Planes and Sections - Answers Frontal/Coronal = Front & Back
Saggital = any left or right vertical
Transverse/Horizontal = across body
Median/Midsaggital = middle
Anterior - Answers front
Posterior - Answers Back
Complete the following about epithelium:
Epithelia form the _______ layer of the body.
Epithelia line....
, Epithelia constitute most ______ tissue. - Answers surface
body cavities and hollow organs
gland
The basal surface of an epithelium is fixed to an underlying connective tissue. What structurally
separates the two different tissue types? - Answers a basement membrane
Are epithelial tissues vascular or avascular? - Answers avascular
What about an epithelial layer allows it monitor the environment through sensory input to the nervous
system? - Answers highly innervated
What is pseudo stratified columnar epithelium? - Answers one layer (simple) of tall cells that appears
stratified
What is transitional epithelium? - Answers multiple layers (stratified) of cells that change shape when
stretched
Which type of epithelium can be keratinized or non-keratinized and how do you know? - Answers
Stratified squamous epithelium. If there is no nucleus in the superficial layers it is keratinized
Where might you find transitional epithelium? - Answers urinary tract
What are 2 cell specializations common to simple columnar epithelia? - Answers Cilia and microvilli
Describe cilia - Answers fingerlike, motile projections that help move along debris/other substances
Describe microvilli - Answers non-motile and serve to increase surface area which increases absorption
Compare the role of cilia to that of microvilli. - Answers Cilia keep substances moving while microvilli
help trap them for absorption
What are the 4 types of tissues? - Answers epithelial
connective
muscle
nervous
What are the 3 basic components all connective tissues share? - Answers cells, protein fibers, and
ground substance
What makes up the extracellular matrix of connective tissue? - Answers protein fibers and ground
substance
What are the 3 main types of connective tissue? - Answers Proper, Supporting, Fluid
