true hormones are
True hormones are chemical messengers produced in one location and transported via the bloodstream to a second location (target cells) where they cause a response in those cells.
water-soluble hormones include
mostly peptides, and catecholamines, which includes adrenaline and noradrenaline
what causes change in hormone release in the posterior pituitary gland
↑ (or ↓) frequency of action potentials leads to
corresponding change in hormone release
is cortisol lipid soluble or water soluble
lipid soluble
is adrenaline lipid or water-soluble
water
lysozyme does what
breaks down cell wall
whats in the epidermis
keratin and phagocytic cells
big difference between skin and mucosal layers
mucosal are live cells
what does the limited specificity of the innate arm mean
it detects
molecular components
shared by many pathogens)
75% of all leukocytes are
neutrophils
three important macrophage actions
phagocytosis, release chemical messengers, show information about microbes to T cells
where do we find dendritic cells
in the blood and in surfaces that are in contact with the environment
what are the sources of endogenous antigen
virus components that are replicating within the cell, or antigen from the cell itself (cancerous maybe) or it’ll be pathogens that have escaped the phagosome.
CD4 T cells can communicate to the B cells through cytokines and what
CD4 can bind to surface bound ligands on the B cells to communicate
whats the last thing i dont think of that can activate the B cells
complement
