ENDOCRINE SYSTEM The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones‚ chemical messengers. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. Endocrine glands do not have a duct system and are called ductless glands. These glands release hormones directly into the blood or lymph. These glands include the pituitary gland‚ the pineal gland

Nervous System Functions of the Nervous System 1. Detect changes and feel sensations 2. Initiate responses to changes 3. Organize and store information Divisions 1. Central Nervous System – brain and spinal cord 2. Peripheral Nervous System – cranial nerves and spinal nerves (relays info to/from the CNS) - Autonomic Nervous System Nerve Tissue – neurons (nerve fibers) and specialized cells (Schwann‚ neuroglia) 1. Neuron cell body contains the nucleus; cell bodies are in the CNS or trunk;

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)

The equine endocrine system is a group of organs that release hormones in the horses body to regulate things like growth‚ metabolism‚ and reproduction. Hormones production is directed by brain signals caused by outside stimuli and it maintained through negative and positive feedback loops. One of the main organs in the endocrine system is the pituitary gland located on the floor of the skull. The hormones produced by the pituitary have a variety of functions from metabolism to reproduction. The most

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 stomach

The endocrine system is the collection of glands that produce hormones that regulate metabolism‚ growth and development‚ tissue function‚ sexual function‚ reproduction‚ sleep‚ and mood‚ among other things. The endocrine system is a very important system in the human body. There are many endocrine glands in this system‚ including -but not limited to- the pituitary gland‚ hypothalamus‚ pineal gland‚ thyroid gland‚ parathyroid glands‚ adrenal glands‚ pancreas‚ gonads‚ placenta‚ thymus‚ heart and gastric

Research each of the following and write a paragraph describing the endocrine gland‚ hormone‚ target tissue‚ symptoms‚ causes‚ and treatment options. 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
