Q

What is Acrylic Resins

A

harder than paraffin wax and are used in cuting harder tissues such as fingernails and undecalcified bone and can use a wider range of stains

Q

What is Epoxy Resins (harder than acrylic resins)

A

harder than __________ and are used in EM (electron microscopy) sections. special glass knives are used to make very thin cuts. Toluidine blue is often the staiin used in these cuts

Q

what is Frozen section

A

used for urgent intra-op diagnosis. tissue is biopsied/excised sent on ice, snap frozen, cut with cryostat, stained, and diagnosis rendere`d and sent back to OR. takes between 15-30 minutes from biopsy to diagnosis

Q

Location and function of glandular epithelium

A

Secretion into a duct

Salivary gland, pancreas, liver, prostate

20
Q

Location and function of transitional epithelium

A

Appearance (basal are cuboidal, surface are dome shaped)

Function: stretches to permit the distension of the organ

Location: lines urinary bladder, ureters, and part of the urethra

21
Q

Location and function of stratified squamous

A

Protection

Skin (keratinized)

Linings of the esophagus, mouth and vagina

22
Q

Stratified cuboidal location and function

A

Secretion

(Typically two cell layers thick)

Rare: found in some sweat and mammary glands

23
Q

Stratified columnar location and function

A

Secretion

Found in the pharynx, male urethra, lining of some glandular ducts, (transition areas between two other types of epithelium in oral cavity and esophagus)

24
Q

Hyaline location and matrix type

A

Soft matrix

Trachea, rib-sternum cartilage

25
Elastic location and matrix type
Elastin matrix Pinna of ears
26
Fibrocartilage matrix and location
Collagen matrix Intervertebral disc
27
Bone matrix includes
Calcium, phosphorus and collagen
28
Cananiculi
Small tubes in bone for nutrients to osteocytes
29
Haversian canal
Central canal
30
Blood contains what 4 things
RBCs WBCs Platelets Plasma
31
RBC's other name and amount in blood and function
Erythrocytes 4.5-6 million/ml Carry oxygen
32
WBCs other name, amount in blood, and function
Leukocyte 4800-10800/ml Fight infection
33
Platelets other name, amount in blood and function
Thrombocytes 150,000-450,000/ml Involved with blood clotting
34
Plasma components/function
Carries dissolved gasses, hormones, nutrients and waste throughout the body
35
Two types of Leukocytes
Granulocytes and Agranulocytes
36
Types of granulocytes and percentage makeup of total leukocytes
50-70% neutrophils - body security and bacteria slayers 2-4% eosinophils - parasites and cleanup of allergic reaction <1% basophils - contain histamine, involved with allergic reaction
37
Types of agranulocytes and subtypes and percentage makeup of leukocytes
3-8% Monocytes - macrophage 25% lymphocytes - T-Lymphocytes: A: Cytotoxic - natural born killers B: Memory - remembers the foreign substance C: Suppressor - stops immune response of T cells B-Lymphocytes: transform into plasma cells - produce antibodies specific to the invader
38
Leukocyte infection level in blood - bacteria or viral
``` 12,000-15,000/ml = viral 15,000+ = bacterial or bad virus ```
39
Connective tissue proper subtypes
Dense: regular, irregular, elastic Loose: areolar, adipose, reticular
40
Neutrophils description and function and %
3 nuclei, light purple interior Body security and bacteria slayers 50-70%
41
Eosinophils description and function and %
Purple/orange, lots of little balls Parasites and cleanup of allergic reaction 2-4%
42
Basophils description, function and %
Blue/purple, one massive colored ball Contain histamine, involved with allergic reaction <1%
43
Monocytes description, function and %
U shaped nucleus, some purple dots Becomes a macrophage 3-8%
44
Lymphocytes description, function and %
Huge nucleus, doesn't take up the whole thing though, larger than basophils Become T and B cells 25%
45
Types and functions of T and B cells
B cells - become plasma cells - produce antibodies specific to the invader T cells - Cytotoxic - natural born killers (bounty hunter) Memory - remembers the foreign substance Suppressor - stops immune response of T cells
46
