Adrenal Gland Layers
Glomerulosa, Fasciculata, Reticularis
Glomerulosa
Aldosterone (Na+/H2O)
Fasciculata
Cortisol (stress)
Reticularis
Androgens
Tropic Hormones
Act on the gland, trigger another hormone
Effector Hormones
Act on peripheral tissue
Anterior Pituitary Gland
Adenohypophysis
Posterior Pituitary Gland
Neurohypophysis (oxytocin, ADH)
Direct Feedback
Only the endocrine system, the endocrine gland acts both as the integrating center and as a tissue that communicates with the target organ
First-Order Feedback
One step (a neuron that releases a neurotransmitter or a neurohormone) between the integrating center and the target organ
Second-Order Feedback
Two steps (a neuron and an endocrine gland) between the integrating center and the target organ
Third-Order Feedback
Loops contain an additional endocrine gland in the pathway, providing a third point of feedback regulation
First-Order Hormones
Oxytocin, ADH
Second-Order Hormones
GH, Prolactin, Melanocyte Stimulating
Third-Order Hormones
HPA, HPI, HPG
