(controlled by prolactin releasing PRF and prolactin inhibiting PIH hormone from hypothalamus follicle-stimulating hormone (FSH) a protein hormone secreted by the anterior pituitary that stimulates the production of eggs by the ovaries and sperm by the testes luteinizing hormone (LH) this anterior pituitary hormone is a tropic hormone. ![]() Stimulates mammary gland development, milk productiion in females may regulate androgen production in males. growth hormone (GH) a protein of about 200 amino acids that affects a wide variety of target tissues and has both direct effects and tropic effects insulinlike growth factors (IGFs) circulates in blood plasma and directly stimulate bone and cartilage growth prolactin (PRL) an anterior pituitary hormone. it's released in response to rise in blood osmotic pressure of fall in blood volume/pressure. neurohypophysis an extension of the brain also called the posterior pituitary oxytocin hormone that the posterior pituitary releases to contract smooth muscles in the uterus and mammary glands antidiuretic hormone (ADH) a posterior pituitary hormone. inhibiting hormones hormone secreted by the hypothalamus that can suppress secretion of hormones by the anterior pituitary posterior pituitary This part of the pituitary does not produce hormones, but stores and releases oxytocin and ADH. releasing hormones make the anterior pituitary secrete its hormones. It consists of the distal part, intermediate part, and infudibular part. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands anterior pituitary produces and secretes several peptide hormones that regulate many physiological processes including stress, growth, and reproduction adenohypophysis the anterior pituitary gland. ![]() hypothalamus the ventral part of the vertebrate forebrain functions in maintaining homeostasis, especially in coordinating the endocrine and nervous systems secretes hormones of the posterior pituitary and releasing factors, which regulate the anterior pituitary pituitary gland the endocrine system's most influential gland. They are extremely potent mediators of a diverse group of physiological processes signal-transduction pathway a mechanism linking a mechanical or chemical stimulus to a specific cellular response tropic hormone a hormone that has another endocrine gland as a target. Prostaglandins (PGs) a group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway.
