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
Types of exocrine glands
- Unicellular - secretory unit is one cell only distributed among normal epithelial cells
Only example in man - goblet cell
- Multicellular - many cells
Types of multicellular exocrine glands
Secretory epithelial sheet - lining of epithelia is secretory
Intraepithelial gland - cells are aggregated in small groups
Specialized invagination of the lining epithelium - GAGO andami nito basahin niyo nalang HAHAHAH p. 19 of manual
T/F endocrine glands have no ducts
True
3 types of connective tissue based on density of fibers
- Loose
- Dense
- Modified loose
Type of connective tissue where fibers are far apart and consist mainly of collagenous fibers
Ordinary loose connective
Type of connective tissue where fibers are far apart, but the tissues have varying histologic characteristics
Modified loose connective tissue
Daming types read on it
Types of modified loose connective tissue
Mucous connective tissue
Reticular connective tissue
Adipose tissue
Pigment tissue
Lamina propria
type of connective tissue supporting epithelium of gastrointestinal and respiratory tracts
Dense connective tissue
Types of dense connective tissue based on pattern of fibers
Dense regular CT
Dense irregular CT
