- Adrenal Gland
- Endocrine System
- Antagonistic Hormones
- a Many hormones work together in pairs to regulate the level of critical substances. These hormones have opposite effects.
- b Excessive insulin causes this, a disorder that causes glucose to be stored rather than used and properly delivered to body cells. This leads to lowered blood glucose concentrations and subsequent release of glucagon and epinephrine. Symptoms include lethargy, dizziness, nervousness, overactivity, and in extreme cases, unconsciousness and death.
- c The endocrine glands and specialized cells as a whole.
- d Modified fatty acids that are secreted by most cells. They accumulate in areas where tissues are disturbed or injured. Some reduce blood pressure, and others raise blood pressure. Some cause smooth muscles to contract while still others cause smooth muscles to relax. Some even cause fever. Aspirin and acetaminophen reduce fever and decrease pain by inhibiting prostaglandin synthesis.
- e One of these is located over each kidney and each has an inner core, the medulla and the outer layer, the cortex. The medulla and cortex function as separate endocrine glands. Secretion of hormones in the medulla is controlled by the nervous system while hormones in the anterior pituitary regulate secretion of hormones in the cortex. The cortex responds specifically to adrenocorticotropic hormone (ACTH), which is secreted by the anterior pituitary gland.
5 Multiple choice questions
- It is suspended from the hypothalamus by a short stalk. The hypothalamus produces hormones that are stored in this gland or that regulate this gland's activity.
- Another way to maintain homeostasis is a positive feedback loop. In this process, release of an initial hormone stimulates release or production of other hormones or substances which stimulate further release of the initial hormone.
- It is caused by insulin deficiency in the body. This condition means that cell are unable to obtain glucose, resulting in abnormally high blood glucose readings.
- The ovaries in females, and the testes in males. These are gamete-producing organs that also produce a group of steroid sex hormones. Sex hormones regulate body changes that begin at puberty.
- Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
5 True/False questions
Luteinizing Hormone (LH) → Stimulate the anterior pituitary to make and secrete hormones.
Puberty → The adolescent stage during which the sex organs mature and secondary sex characteristics, such as facial hair appear. In males, during this stage, sperm production begins, the voice deepens, the chest broadens, and hair begins to grow on the body and face. In females, the menstrual cycle begins, the breasts grow, and the hips wide.
Releasing Hormone → Stimulate the anterior pituitary to make and secrete hormones.
Neurosecretory Cells → Specific cells that hormones travel to, to produce a specific effect.
Second Messenger → Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
