Manual Flashcards
T/F protein staining
At a given pH, if the reactive carboxyl group is dominant over the reactive amino group, the structure will be stained by the basic dye
T
T/F nucleic acid staining
Nucleic acids will stay negatively charged (and therefore basophilic) at alkaline, neutral, and moderately acidic pH.
T
Tapos at very acidic pH, unstainable na (non-ionized)
T/F
Mucopolysaccharides and mucoproteins will stay negatively charged (and therefore basophilic) at alkaline, neutral, and moderately acidic pH.
T
Same as nucleic acids
Why are mucopolysaccharides and mucoproteins very acidic?
Sulfate groups
Which biomolecules require special staining (accdg to the manual)?
Fats and carbohydrates
Which cells have no nuclei?
Rbcs
Keratinized cells
4 main types of tissue
Epithelial
Connective
Muscle
Nervous
T/F
Epithelial tissue is derived from all germ layers
T
Classifications of epithelial cells based on shape
Squamous
Cuboidal
Epithelial
Classifications based on number of cell layers
Simple
- pseudostratified
Stratified
Transitional (idk under which siya baka iba)
Which layer of the epithelium is used for classification
Most superficial layer
T/F
In any stratified epithelium, basal cells are either cuboidal or columnar
T
Why does pseudostratified epithelium appear stratified?
Different nucleus heights
Other structural features that can be used to classify epithelium
Cilia
Goblet cells
Keratinization
Two types of glands and their differences
- Exocrine - empties onto body surface
2. Endocrine - secretes via intercellular portion of connective tissue to the blood or lymph
