Within the endocrine system are endocrine glands which control such things as growth, reproduction, heart rate, energy, and many others functions (Comer, 2011). Endocrine glands then release chemicals known as hormones, which are released into the bloodstream. These hormones then cause different responses in the body’s organs. If any of these systems is malfunctioning they may indeed cause abnormal behavior especially behaviors associated with psychological functioning.
