Document Summary
Hypothalamus info goes into hypothalamus which sends signaled to the pituitary. Phih (dopamine) (prolactin hormone inhibitory hormone) inhibits prl release. Trh and a possible phrh (prolactin hormone releasing hormone) stimulate prl release. Neurotransmitters an act as hormones because they can go into the blood. When they travel through blood to a target cell they are classified as a hormone. 22 kda protein, 198 amino acids: over 300 functions fluid balance, milk production, controls fluid inside womb, all about fluid balance inhibited by dopamine (phih) Then pituitary prl breast sucking from baby cns back to start as this is a stimuli. Only positive feedback loops in humans are involved in reproduction. Stimulates the release of lh/fsh: target organs are gonads ovaries and testes. Lh luteinizing hormone: affects growth and development of eggs/sperm, stimulates steroidogenesis, producing steroids that are needed by reproductive system. Fsh follicle stimulating hormone: follicular growth in females (how eggs are produced, sperm development in males.
