In the infundibulum, the primary capillary network plays a crucial role in transporting releasing hormones from the hypothalamus to the anterior pituitary gland. These releasing hormones are produced by specialized neurosecretory cells in the hypothalamus and are responsible for regulating the release of hormones from the anterior pituitary.
The releasing hormones are released into the primary capillary network, which then transports them to the secondary capillary network in the anterior pituitary. The secondary capillary network is located in close proximity to the endocrine cells in the anterior pituitary and allows for efficient exchange of hormones between the capillaries and the endocrine cells.
The releasing hormones released into the secondary capillary network stimulate or inhibit the release of specific hormones from the endocrine cells in the anterior pituitary. These hormones then enter the systemic circulation and travel to their target organs or tissues, where they exert their physiological effects.
Overall, the primary and secondary capillary networks in the infundibulum and anterior pituitary play a vital role in the regulation and control of hormone release, ensuring proper communication between the hypothalamus and the anterior pituitary gland.
