|
|
What is the blue arrow? Black arrow?
|
blue arrow: keratonized part of stratified squamous epithelium
black arrow is the entire stratified squamous epithelium tissue (keratonized) |
|
what type of tissue?
|
endothelium (epithelium in blood and lymph vessels)
|
|
what type of tissue and where is it found?
|
transitional epithelium
found in the urinary bladder |
|
What is in the red circle? What is the green line due to?
|
Desmosome joining two cells
The green line is the INTERMEDIATE LINE, due to an increase in glycalyx also note the increase in cytoplasmic density around the desomosome due to lots of microfilaments present to strengthen the junction. |
|
What are the red arrows pointing to?
|
microvilli
|
|
what are the black arrows pointing to?
|
cilia
|
|
what are the black arrows pointing to?
What are the red arrows pointing to? |
black=cilia
red=microvilli |
|
what are these? what is the blue arrow pointing to?
|
cilia! note 9 sets of doublets and 2 central singlets.
blue arrow=plasmalemma, which surrounds each cilia |
|
What type of tissue is this? What makes it distinct?
|
Embryonic connective tissue, MESENCHYME
the DARK nucleouslus is a destinct characterstic |
|
what type of cells are circled in yellow?
|
mast cells
|
|
what are the blue and black arrows pointing to?
|
black=mast cell
blue=collagen fibers |
|
what are the yellow arrows pointing to?
|
elastic fibers
|
|
What is the red arrow and what is there in life?
|
adipocyte.
in life it is filled with one fat globule, but the fat is removed during processing for microscopy. |
|
What types of cells are these and how can you tell? What is their function?
|
Plasma Cells
Darkly stained b/c very basophilic b/c lots of rER. chromatin clumps around periphery of nucleus giving it a "cart wheel" appearance. Synthesize and secrete humoral antibodies. |
|
What does the blue line denote?
|
the separation between the dermis and epidermis of the skin.
Epidermis=stratified squamous keratonized epithelium Dermis=dense irregular connective tissue |
|
What is this tissue?
|
Dense connective tissue
|
|
what type of tissue is this? what are it's unique characteristics and what are the main cells?
|
Dense Regular Connective Tissue
-parallel collagen fibers - cells are mostly fibroblasts |
|
What type of cells are present in this slide?
|
N = neutrophil (light purple, 3-5 nuclei lones)
E = eosinophil (2 nuclie lobes, pink) B = basophil L = lymphocyte (same size as rbcs, dark nucleus) M = monocytes (big, light irregular shape nucleus P = platelets (small fragments of cytoplasm surrounded by plasmalemma) |
|
What type of tissue is this? What cells are on the right and on the left?
|
Embryonic Hyaline Cartilage
Left: Chondroblasts (in the process of secreting matrix) Right: Mesenchymal cells |
|
What are the black arrows pointing to?
Red Arrows? Green arrows? |
black is pointing to periphery of hyaline cartilage, the newer, smaller lacunae which contain chondroblasts.
red is pointing to chondrogenic layer, containing chondroblasts that have not yet secreted matrix green is pointing to FIBROUS LAYER, containing collagen fibers, fibroblasts and mesenchymal cells |
