Verified step by step guidance

Understand the context: The hypothalamus is a region in the brain that plays a critical role in regulating various physiological processes, including hormone secretion. It is connected to the pituitary gland via a specialized vascular system known as the hypothalamic-hypophyseal portal system.

Learn about the capillary plexuses: The hypothalamic-hypophyseal portal system consists of two capillary networks. The first capillary network, located in the hypothalamus, is referred to as the primary capillary plexus. The second capillary network, located in the anterior pituitary, is called the secondary capillary plexus.

Clarify the function of the primary capillary plexus: The primary capillary plexus is responsible for receiving neurohormones (e.g., releasing and inhibiting hormones) secreted by hypothalamic neurons. These hormones are then transported via portal veins to the secondary capillary plexus in the anterior pituitary.

Differentiate between the terms: The term 'glomerular' refers to a capillary network in the kidneys, not the hypothalamus. The term 'portal' refers to the vascular connection between the hypothalamus and pituitary, but it does not specify the capillary plexus. The correct term for the capillary network in the hypothalamus is 'primary capillary plexus.'

Conclude the explanation: Based on the anatomical and physiological context, the capillary network associated with the hypothalamus is the primary capillary plexus, which is part of the hypothalamic-hypophyseal portal system.
