Molecules can move between cells if they are nearby
Cells can use electrical impulses (neural)
Cells can use chemical messengers (hormones)
The Endocrine System
Hormones are chemical messengers that are produced in special types of cells (secretory cells)
and can have their effect;
o Within the same cell (autocrine)
o On nearby cells by moving into the tissue fluid and then interacting with neighbouring
cells (paracrine)
o Cells far away as they are released into the blood stream and transported around the
body (main type) (endocrine)
Hormones:
In general terms, hormones are;
o Slow to act
o Long lasting
Hormones will only cause a response in a cell that has a specific receptor for that hormone
o Some cells have multiple receptors for multiple hormones
o Some cells that have one receptor for one hormone
o A reaction in the one type of cell to a particular hormone may be different to the
reaction cause in a different type of cell
