Document Summary
As a hormone acts on target cells (and changes an amount of substance they release), then the hormone also acts on the endocrine cells which regulates further output of the endocrine gland. This is using a negative feedback system: peptide hormones: a string of amino acids (if the string is long enough it can be called a protein hormone). Each endocrine gland secretes specific hormones: pituitary, posterior pituitary: secretes oxytocin and vasopressin, which stimulates uterine muscle contraction/milk letdown reflex, and the constriction of blood vessels, respectively, anterior pituitary: secretes 6 main topic hormones. Hormonal and neural systems interact to produce integrated responses: hormonal and neural systems work together to produce responses. There are 4 types of signals between these 2 cells, endocrine-endocrine, endocrine-neural, neural-endocrine, neural-neural. Changes in hormone release affect behaviour, which affects experience, which then affects hormone release. Major difference between these 2 systems is their signal specificity.
