*The endocrine system

• Differences between NTs and Hormones

  NTs are produced within neurons and pass very quickly from one neuron across the synaptic cleft to another nearby neuron whereas hormones are secreted by glands and travel less quickly through the bloodstream to often quite distant target organs
• Hormones are chemicals produced by glands of the endocrine system. Upon the brain's signals, hormones are secreted into the bloodstream by glands and travel to 'target cells'. The hormone then exerts an influence on the target cell by stimulating receptors on the surface of or inside the cell

• The endocrine system contains glands which produce hormones that have many regulatory functions such as metabolism, development, tissue function, sexual functions, reproduction, sleep and mood.
• The endocrine system provides a chemical system of communication through the bloodstream with each type of hormone targeting specific organs and tissues (e.g. ALTH triggering the adrenal gland to release corticosteroids, resulting in a stress response)
• The Pituitary gland helps regulate the function and secretion of other glands in the endocrine system and releases prolactin (helps lactation)
• The Adrenal gland secretes adrenaline and responds to the sympathetic division during the fight or flight response
• The Thyroid gland secretes thyroxine which regulates the metabolism rate and growth
