Document Summary

Control of blood glucose and other nutrients. Sits in the sella turcica: of the sphenoid bone. Posterior pituitary (neurohypophysis: originates in neural tissue, secretes 2 hormones (neurohormones) Anterior pituitary (adenohypophysis: originates from the embryonic oral cavity, secretes 9 hormones. Controls the pituitary gland: anterior 7 hormones (5. Releasing, 2 inhibiting: posterior action potentials. Influences on the hypothalamus: hormones, sensory information and emotions. Reaches the anterior pituitary: through the. Releasing hormones: secretes anterior pituitary hormones, travels through the circulation to target tissue. Inhibiting hormones: prevents anterior pituitary hormone secretion. Hypothalamic neurons: receives stimulus, changes the ap frequency. Hypothalamus synthesizes the hormones: stored in the axon ends, travels through the circulation to target tissue. Increased ap frequency: releases posterior pituitary hormones. Decreased ap frequency: prevents posterior pituitary hormone release. Osmolality changes: baroreceptors senses bp changes. Overhydration/ increased bp: decreases adh secretion, decreases water reabsorption. Target tissues: ureters and mammary glands. Stimulus: uterus stretching, breast nipple stimulation.
