endocrine system communication :(((

is this even on the test idk

types of cell communication

cell to cell contact, short distance communication, long distance communication

cell to cell contact

plasmodesmata in plant cells and gap junctions in animal cells provide pores through which signaling molecules can pass materials, used by the immune system

short distance communication

cells release chemical signals for nearby cells, neurotransmitters are released by neurons and accepted by other neurons, plant immune response and quorum sensing in bacteria

quorum sensing

bacteria release signaling molecules that coordinate gene expression, once a certain threshold level of signaling molecule concentration is reached, gene expression occurs at the same time, bioluminescence and biofilms

long distance cell communication

cells of the endocrine system release signaling molecules that travel long distances and elicit responses from other cells and tissues (hormones)

human growth hormone (HGH)

stimulates growth of bone and muscle tissue, produced by anterior pituitary of the brain

insulin

causes cells to take glucose from the blood, produced by the pancreas

testosterone

produces male sex characteristic, produced by testes

estrogen

produces female sex characteristics (menstrual cycle), produced by ovaries
