Applied Human Science – CHAPTER 1 1. Which Organ system maintains a relatively slow-acting degree of control over most bodily functions? Endocrine System (hormones act in minutes to hours‚ in contrast to nerve impulses‚ which act in fractions of a second). 2. The esophagus and the trachea run side-by-side through the thorax. In which systems are these organs found? The esophagus belongs to the digestive system‚ and the trachea belongs to the respiratory system. (The esophagus carries food to the

Invertebrate Endocrinology Overview of the Endocrine System * System of ductless glands that secrete hormones * Hormones are “messenger molecules” * Circulate in the blood * Act on distant target cells * Target cells respond to the hormones for which they have receptors * The effects are dependent on the programmed response of the target cells * Hormones are just molecular triggers * Basic categories of hormones * Amino acid based: modified amino acids (or amines)

Hormones and the Endocrine System 26.1 Chemical and electrical signals coordinate body functions The Endocrine System is a group of interacting glands and tissues throughout the animal body that produce and secrete chemical to initiate and maintain body functions and activities. Chemical Signals -Hormones - are released into the bloodstream by endocrine cells and carried to all locations in the body Consists of all hormone secreting cells Works with the nervous system in regulating body activities

The Endocrine System Exercise 1: The Pituitary Gland obseRvations A. Please describe in detail the structures and features you observed on the pituitary gland slide. The Pituitary Gland Slides The Anterior Pituitary Gland was darker than the Posterior Pituitary Gland. In the Anterior Pituitary Gland Slide you can see Chromophobes and Acidophiles. Not super easy to distinguish which is which though. The Posterior Pituitary Gland slide showed Pitulcytes (Neuroglia) as light purple

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

Human chorionic gonadotropin (hCG) Human chorionic gonadotropin‚ or hCG‚ is a hormone that helps with the development of an egg in a woman’s ovary‚ as well as the release of the egg during ovulation. If the body doesn’t produce enough hCG on it’s own‚ you can receive injections of it. The injections aren’t for women only‚ they can be used in men to

Endocrine The endocrine gland system helps produce and deliver hormones. These help take control of many important body parts. It also helps your body change your calories into energy. Endocrine system is important because it impacts how your heart beats‚ how your tissues grow and even if you can have a baby. It also plays a role if you would or wouldn’t develop thyroid‚ growth disorders‚ or a host of other hormone related disorders. The glands of the endocrine system let go of specific hormones
