| Question | Answer |
|---|---|
| Communication between different parts of the body is critical to maintaining | .Homeostasis |
| Communication requires signals. In the body, signals can be either | Electrical or Chemical |
| Electrical | The nervous system |
| Chemical | The endocrine system |
| Signals that travel through the blood | Hormones |
| Is a complex network of glands and organs that produce and release hormones to regulate various physiological functions in the body. | The Endocrine System |
| These are chemicals secreted by various structures in the body that travel | Hormones |
| For a hormone to interact with a target | that target must have receptors that will bind the hormone. |
| Lipid | derived hormones pass easily through membranes. |
| Because of this, receptors for lipid-derived hormones are found in the | Cytoplasm or the nucleus of the cell. |
| Hormones that are not derived from lipids do not pass easily through cell membranes. Because of this, their receptors are found | The surface of the target cells. |
| Hormones and the glands that secrete them are important components of negative feedback loops. What part of a feedback loop do glands and hormones belong? | Control center of the feedback loop. |
| Leads your nervous system and endocrine system | Hypothalamus |
| How does the hypothalamus influence other endocrine glands? | It secretes hormones that stimulate or suppress the release of hormones and the pituitary glands. |
| Stores and releases two hormones. | Posterior pituitary |
| The posterior pituitary stores and secretes | AntidForone (ADH) |
| What is the effect of AntidForone (ADH) hormone? | Regulates water balance |
| Where is AntidForone (ADH) hormone produced? | The posterior pituitary |
| a hormone and neurotransmitter that plays a crucial role in various physiological and behavioral functions in the human body. | Oxytocin |
| What is the effect of Oxytocin? | Labor and Bonding |
| Where is Oxytocin produced? | The posterior pituitary |
| The hypothalamus communicates with | the posterior pituitary via the hypophyseal tract |
| The anterior pituitary produces and secretes the following hormones. | Adrenal corticotropic hormone , Thyroid stimulating hormone |
| Stimulates your adrenal glands | Adrenal Corticotropic Hormone |
| Thyroid Stimulating Hormone | Triggers your thyroid release hormones, Mainly impacts metabolism. |
| They simulate follicular growth and ovulation. | Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) |
| Helps with milk production | Prolactin |
| Help you grow | Growth Hormone |
| How is the activity of the anterior pituitary regulated by the hypothalamus? | It secretes the release of hormones. |
| this part of the adrenal gland secretes a number of hormones. NONE OF THEM ARE ADRENALINE | Adrenal Cortex |
| Aldosterone | Regulates water and sodium in the body |
| Cortisol | Regulating your body’s stress. |
| Reduce Sexual Desire | Weak Androgens |
| Adrenal medulla | this is the part of the adrenal gland that comes to mind when people think of the adrenal gland. |
| To increase cardiac output and to raise glucose levels in the blood. | Epinephrine/Norepinephrine |
| Regulate your metabolism and growth | Thyroid Hormone |
| Regulate your calcium levels by decreasing them. | Calcitonin |
| Make the parathyroid hormone. | Parathyroid glands |
| Regulates the amount of calcium, phosphorus, and magnesium | Parathyroid hormone |
| Insulin and Glucagon are produced by | Pancreas |
| Produces enzymes that help digest food and insulin. | Insulin |
| Long side of insulin to control blood sugar levels. | Glucagon |
| Inhibits the pituitary glands secretion of growth hormone and TSH. viii. Endocrine disorders | Somatostatin |
