4
Q
These are stored nutrients in the cell that may or may not be present in a cell.
A
Inclusion bodies
5
Q
Identify the inclusion body
- yellow-brown pigment composed of residues of lysosomal digestion
- represents cellular age (senescence)
- tends to accumulate in cells that are not undergoing mitosis
A
Lipofuscin
6
Q
Identify the inclusion body
- storage form of glucose
- stored in skeletal muscles and liver
- not stained with H&E (appears like clear areas)
- requires special stain such as Periodic Acid Schiff (Red in color)
A
Glycogen
7
Q
Identify the inclusion body
- appears brownish
- indigestible residue of hemoglobin
- can be normally found in the red pulp of the spleen (red pulp for veins btw).
- Often results from bleeding when red cells and hemoglobin are degraded by macrophages
- alveolar macrophage if there are hemorrhages in the alveoli.
A
Hemosiderin
8
Q
Identify the inclusion body
- Adipose cells
- Accumulates through time in adipocytes displacing all organelles and nucleus into periphery.
- Extracted by solvents during tissue preparation, thus appears “hole in the cytoplasm”
A
Adipose or Lipids
9
Q
Identify the inclusion body
- brown pigment
- found on the basal layer of the epidermis (stratum basale)
A
Melanin
10
Q
outermost boundary of the cell that regulates the passage of molecules
A
Cell membrane
11
Q
what do you call something that consists of hydrophobic and hydrophilic parts?
A
amphipathic
