Tissue preparation and staining — Flashcards

Flashcard 1: The intermediate filament Desmin is found in _____ cells

Answer: muscle

Flashcard 2: Which skin layers (2) contain nerve endings, blood vessels, lymphatics, and adnexal structures (e.g. hair follicles, glands)? _____

Answer: Dermis and hypodermis

Flashcard 3: Deep partial thickness burns involve which layers of the skin?_____

Answer: Epidermis, Superficial Dermis, Deep Dermis

Flashcard 4: The intermediate filament Vimentin is found in _____ tissue

Answer: mesenchymal

Flashcard 5: Can microglia be distinguished by Nissl stain histologically? _____

Answer: No

Flashcard 6: Which type of filament is predominantly involved in maintainence of cell structure? _____

Answer: Intermediate filaments (e.g. desmin, cytokeratin)

Flashcard 7: Langerhans cells are specialized _____ cells predominantly found in skin

Answer: dendritic

Flashcard 8: Embryological origin of the dermis?

Answer: Mesoderm (and Neural Crest) :: mostly derived from Mesoderm (lateral plate and paraxial), but facial dermis is from Neural Crest.

Extra: The dermis has a dual origin: 1. Paraxial mesoderm (dermatome): Dermis of the back. 2. Lateral plate mesoderm: Dermis of the ventral body wall and limbs. 3. Neural crest cells: Dermis of the face and anterior neck.

Flashcard 9: What organelles are stained with Nissl substance?

Answer: RER

Flashcard 10: What type of cytoskeletal element is most associated with cell structure?

Answer: intermediate filaments
