Document Summary

Chemical messengers that are able to travel out to the peripheral. Send messages to different parts of the body. Endocrine hormones in turn have profound effects on brain functioning through feedback systems. Many endocrine glands are influences by the pituitary (aka master gland) Pituitary is controlled by many hormones secreted from the hypothalamus. Nerve cells communicate through the release of neurotransmitters. Controls releases of hormones that can influence the release of cytokines from the immune system. Immune system operates though the release of cytokines. Modulate both neural activity and the release of hormones by the release of cytokines. Cognitive sensory stimuli influences neural, immune and endocrine activity. Non cognitive stimuli influences the systems through their action on the immune system. Regulated by neurotransmitters released from nerve cells (neurons) from the brain. Hormone feedback - from specific nerve cells can modulated by the level of specific endocrine hormones in the circulation.
