Explanation:  The interface between the neural and endocrine systems is the hypothalamus, which through the pituitary gland controls the function of the peripheral endocrine glands. The hypothalamus, as a component of both the neural and endocrine systems, monitors the hormones secreted by the endocrine system, i.e. endocrine glands, to provide feedback that goes to the brain for processing. The pituitary gland, as one of the endocrine glands, is also controlled by the hypothalamus, meaning that the hypothalamus controls the secretion of hormones into the blood based on the needs determined by the processed brain data.
