Endocrine system — function?
Regulates physiological processes via hormones.
Hormones — function?
Chemical messengers regulating physiology.
Hormone classes — primary types?
Peptides, steroids, and amines.
Negative feedback — role?
Maintains hormone balance and homeostasis.
Feedback mechanisms — key role?
Maintain hormonal balance through regulation.
Hydrosoluble hormones — receptor type?
Bind to membrane receptors.
Liposoluble hormones — effect?
Alter gene transcription, slower response.
Pulsatile secretion — importance?
Maintains receptor sensitivity.
Hypothalamic-pituitary axes — example?
HPA, HPT, HPG, GH-IGF-1, prolactin.
Hormone transport — liposoluble?
Bound to carrier proteins.
