Endocrine Introduction Part 1
• Endocrinology: basic conceptso Endocrinology is the study of:
▪ The biosynthesis, storage, biochemistry and
physiological function of hormones
▪ The cells of the endocrine glands which secrete
hormones
▪ The pathways involved with the transport of hormones to
their target cells (via CV system)
▪ The extracellular and intracellular pathways associated
with mediating hormone actiono What are the functions of a
hormone?
▪ Essential to human life
▪ Serve as the molecular links to connect organ systems
and biological fluids in the human body
▪ Essential to allow body to response to external stimuli
▪ Required at all stages of development- hormone levels
change within the individual
▪ Regulate the production, storage and utilization of
energy
▪ Crucial to maintaining homeostasis
▪ They tie the whole body together o Classical definition
of a hormone

▪ Molecule produced by a gland and secreted in
small amounts into the blood stream→transported to distant
organs to exert specific effects
▪ Made in one site and used on another site (CV
helps transport)
▪ They are like catalysts
• Small amounts are very potent
• Need to change things very quickly so don’t have time to
make a lot of it
• They trigger cascade/amplification effects= don’t need a
lot of themo The body has several systems to mediate
function
Nervous System
Endocrine System
Cell Type
Neurons
Glandular epithelium
cells
Messenger
Neurotransmitter
Hormone

Document Summary
Endocrine introduction part 1: endocrinology: basic concepts o endocrinology is the study of: The biosynthesis, storage, biochemistry and physiological function of hormones. The cells of the endocrine glands which secrete hormones. The pathways involved with the transport of hormones to their target cells (via cv system) Serve as the molecular links to connect organ systems and biological fluids in the human body. Essential to allow body to response to external stimuli. Required at all stages of development- hormone levels change within the individual. Regulate the production, storage and utilization of energy. They tie the whole body together o classical definition of a hormone. Molecule produced by a gland and secreted in small amounts into the blood stream transported to distant organs to exert specific effects. Made in one site and used on another site (cv helps transport) Need to change things very quickly so don"t have time to make a lot of it.
