Question

Quizplus · Accepted Answer

The endocrine system consists of glands, such as the pituitary, thyroid, and adrenal glands, that release hormones into the bloodstream to regulate the activities of certain organs. It does not directly control complex mental functions or connect the brain and spinal cord to the rest of the body. The release of neurotransmitters is a function of the nervous system, not the endocrine system.
