Document Summary
Explain homeostasis and how the endocrine system is involved. Know the endocrine glands and associated hormones that are released. Describe how a neurotransmitter differs from a hormone. Understand the different classes of hormones and their unique properties. Explain the relationship between the hypothalamus, anterior and posterior pituitary gland. Describe the function of vasopressin (adh) and how it signals its target cell. Endocrine system uses hormones for cellular signalling to distant sites throughout the body. Hormone chemical signal secreted into the bloodstream to act on a distant tissue. Response requires the presence of a receptor. Target cell cell that has receptor that binds the hormone. Different cells may have different responses to the same hormone. Note: hormones can be produced in glands or within cells of an organ. Pituitary gland site where several hormones are released which control reproduction, body fluid volume, metabolism, growth, etc.
