In up-regulation, the number of receptors increases in response to rising hormone levels, making the cell more sensitive to the hormone and allowing for more cellular activity. of 10 amino acids. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. Many of the hormones are secreted in response to signals from the nervous system, thus the two systems act in concert to effect changes in the body. The A1C test measures average blood-glucose levels over the past two to three months. Its secretion at the onset of puberty triggers, sexual development, and from then on it is essential for normal sexual physiology in, both males and females. Building Vocabulary: Animal Structure and Function. Two hormones that counteract one another's actions in a feedback circuit are said to be ______ hormones. For example, the anterior pituitary signals the thyroid to release thyroid hormones. A. regulate growth ______ is the maintenance of the relative constancy of an animal's internal environment despite changes in the external environment. I”VE DONE THE FIRST ONE FOR YOU! Maintaining homeostasis within the body requires the coordination of many different systems and organs. The thymus produces hormones referred to as thymosins, which contribute to the development of the immune response in infants. D. gonads. It contains both exocrine cells that excrete digestive enzymes and endocrine cells that release hormones. Missed the LibreFest? A. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. Anatomy is the study of the structure of an organism's body parts, while physiology is the study of the function of those parts. EPO triggers the formation of red blood cells in the bone marrow. The liquid component of blood is called __________. Use Creately’s easy online diagram editor to edit this diagram, collaborate with others and export results to multiple image formats. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. C. regulate production of other hormones Many endocrine diseases are diagnosed using tests that stimulate or suppress endocrine organ functioning. The _____ is the master control center for the endocrine system. Once a disease such as diabetes has been diagnosed, endocrinologists can prescribe lifestyle changes and medications to treat the disease. Endocrine System Concept Map. The signal travels along these nerves, and then to the spinal cord and brain. largest class of hormones, eg. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Hormone production and release are primarily controlled by negative feedback, as described in the discussion on homeostasis. The liquid portion of your blood is called _____. Some organs possess endocrine activity as a secondary function but have another primary function. Among the cell types in each pancreatic islet are the alpha cells, which produce the hormone glucagon, and the beta cells, which produce the hormone insulin. The completion of meiosis II during oogenesis occurs at ________________. The changes brought about in the receiving cells affect the functioning of the organ system to which they belong. The testes produce androgens, testosterone being the most prominent, which allow for the development of secondary sex characteristics and the production of sperm cells. Pulmonary mechanics II 17 Terms. The endocrine system helps to regulate a variety of bodily functions through the secretion of hormones. receptor tyrosine kinases. Start studying Endocrine system Concept Map. Creately is an easy to use diagram and flowchart software built for team collaboration. Increasing levels of these hormones in the blood then give feedback to the hypothalamus and anterior pituitary to inhibit further signaling to the thyroid gland (Figure 16.4.2). Two of these hormones regulate ion concentrations and blood volume or pressure.

Calcitonin is released in response to rising calcium ion concentrations in the blood and has the effect of reducing those levels. Parathyroid hormone increases blood calcium concentrations when calcium ion levels fall below normal. The pituitary gland is located at the base of the brain. The endocrine glands differ from the exocrine glands. Legal. The endocrine system coordinates with the nervous system to control the functions of the other organ systems.
