Which of the following cytokines plays a significant role in hematopoiesis by stimulating production of blood cells from bone marrow?

What is the primary role of the hypothalamus in regulating the HPA axis?

Hormones are only classified chemically as amino acid-based, excluding steroid hormones.

Hormones exert effects solely by altering membrane permeability, not through binding to receptors.

Hormone release is regulated solely by positive feedback mechanisms.

Interactions of different hormones on the same target cell never involve synergism or permissiveness.

The hypothalamus does not play a role in controlling the pituitary gland through releasing and inhibiting hormones.

The hypothalamus secretes hormones that are transported directly to the anterior pituitary gland through a portal system.

The posterior pituitary gland secretes oxytocin and cortisol to regulate body functions.

In the context of hormone interactions, antagonism occurs when one hormone enhances the response of another hormone on a target cell.

High receptor affinity means that a lower hormone concentration is needed to achieve the same biological response.

Increasing the number of receptors on a target cell always leads to an increased cellular response to hormones.

Cortisol, the end product of ACTH action, exerts positive feedback on the HPA axis.

Elevated cortisol levels signal the hypothalamus and pituitary to increase the release of CRH and ACTH.

ACTH secretion follows a random pattern throughout the day, with no specific peak time.

Stress triggers a decrease in ACTH and cortisol release from the adrenal glands.

Understanding hormone receptor affinity is not important when considering the body's adaptation to stress.

The hypothalamus secretes vasopressin to signal the posterior pituitary gland to release antidiuretic hormone (ADH).

A hormone with low receptor affinity would require a higher concentration in the blood to achieve a response compared to a hormone with high receptor affinity.

In the hypothalamic-pituitary axis, positive feedback loops are more common than negative feedback loops.

Multipotent progenitor cells give rise to unipotent progenitor cells in the process of hematopoiesis.

The concentration of a hormone in the blood is solely determined by its rate of secretion and has no relation to its rate of metabolism or elimination.
