	Hormones “orchestrate” responses in other tissues, including other endocrine organs, and these overall effects can be similar or different in different tissues. These signaling pathways are often described as "axes" the two major types are the: '''HPA''' ('''H'''yothalamus-'''P'''ituitary-'''A'''drenal) and '''HPG''' ('''H'''ypothalamus-'''P'''ituitary-'''G'''onad). These hormone effects (like music) can be rapid, slow, brief, diurnal, or long-term. Hormone effects can be mimicked, stimulated, and blocked by therapeutic drugs, nutritional and environmental chemicals. Importantly, fetal endocrine development is required for normal fetal growth and differentiation.
