205. Hypothalamus (nerve), pituitary (nerve and endocrine), ovaries, testes,  prostate, uterus, placenta  

206. Peptides: few AA, no chains, small simple structure. Proteins: long chains of  AA. Glycoprotiens: protein chains and carbohydrates

207. Derive from cholesterol. Lipid molecule, receptors in cell

208. Derive from lipids. ½ life short, trigger inflammation  

209. Ejaculation

211. Milk let down

212. Single polypeptide chain

213. Attached carbohydrates in cellular membrane. a and B subunits determine  action.

214. Common among hormones

215. Unique for each hormone

216. Biological activity  

217. Two polypeptide chains with alpha and beta subunits

218. Inhibin, Activin

219. Prostaglandins. Archidonic acid (unsaturated fatty acid)

220. Most tisses: autocrine, paracrine, endocrine actions. Lungs 221. Smooth muscle contractions, lipid metabolism, mediate inflammation 222. Vasodilation, CL maintenance, ovulation

223. Vasoconstiction, CL regression, partuition

224. Cholesterol, sex steriods, and corticosteriods. Cholesterol

225. Cholesterol – (enzymatic conversion) – (pregenolone) – progesterone –  testosterone – estradiol  

226. Feedback regulation. Postive and negative  

227. Number of receptors on or in cell

228. Hypothalamus for FSH and LH

230. Blood stream

231. Protein hormones

232. Act at low concentrations, short half-life, binds to specific receptors, regulate  intracellular biochemical actions

234. Affector of hormone (receptor), induce intracellular cascade  235. MRNA – Proteins  

236. Episodic, basal, sustained

237. Binds cell surface geometric configuration receptor affinity  238. Cell membrane receptors- fast response. Nuclear receptors- slow response 239. Water; transport proteins; specific  

240. Cervical mucus during estrus, uterine secretions, seminal fluid secretions 241. Hormone released in bursts, varying in duration and quantity 242. Steady secretion for extended time (progesterone during pregnancy) 243. Hormone remains low and fluctuates with amplutude (GnRH secretion) 244. Liver

246. Vareis with cell type, up or down regulation receptor, number by hormone

247. Time is takes for hormone in blood to be reduced in ½ / rate hormone cleared from system. Depends on size, type, binding

248. Rapid hormone activity turnover  

249. Biological response  

250. Mimic hormone and bind receptors with similar or greater biological activity.  Used to treat animals

251. Take place of hormone, prevent binding, infere hormone effect. Bind receptor  with greater affinity than native hormone
