BIO106 Study Guide - Quiz Guide: Exocrine Gland, Anterior Pituitary, Myeloma Protein
Document Summary
Name three ways in which a hormone typically causes change. Alter plasma membrane permeability/membrane potential; stimulate synthesis of enzymes/proteins; activate or deactivate enzymes: briefly describe humoral, neural and hormonal stimuli of endocrine glands. Humoral stimuli are when changing blood levels of ions and nutrients directly stimulate secretions of hormones. Neural stimuli are when nerve fibers stimulate hormone release. Hormonal stimuli are when hormones stimulate other endocrine organs to release their hormones: the posterior pituitary gland creates two hormones. Oxytocin and adh; oxytocin is a strong stimulant of uterine contractions released during childbirth and as hormonal trigger for milk ejection. Gigantism is a hypersecretion of gh usually caused by an anterior pituitary tumor. It occurs in children and they can reach heights over 8 feet: name the six anterior pituitary gland hormones.
