Microanatomy of immune system Flashcards
immune privileged sites
immune system has different role (ex: no immune response)
* eye (inside)
* brain (has immune response, just seperate, microglia)
* testes
* placenta/fetus
innate immune system
general
immediate
diffuse (scattered around)
adaptive immune response
specialized
delayed
focused
innate immune response cells
- neutrophils
- macrophages
- complement
- NK cells
- gamma delta T cells
innate immune response cells
- neutrophils
- macrophages
- complement
- NK cells
- gamma delta T cells
adaptive immune response cells
T cells (cytotoxic and helper)
B cells (antibody)
structures associated with adaptive immunity
- lymph node (lymph)
- spleen (blood)
- tonsil (oropharyngeal)
- mucosa associated lymphoid tissue
- thymus
- bursa of Fabricius (bone marrow)
afferent
coming in
efferent
going out
lymph node
periarteriolar lymphoid sheath (PALS)
in spleen
follicles with proliferating lymphocytes
germinal center
lymph node label:
follicle
* outer rim
* proliferative zone
subscapular sinus
cortex
What is this?
medulla of lymph node with medullary sinus
What organ?
Label:
* blood vessel
* smooth muscle
* PALS (white pulp)
spleen
What is this?
label:
* proliferative center
* blood vessel
spleen white pulp/follicle/PALS
