Endocrine system Lecture 19 and 20 1  Outline Endocrine system PART-1: General cascade Endocrine vs Nervous system PART-2: Hormones Types of hormones PART-3: Glands Types of glands PART-4: Functioning model of endocrine system 2  General cascade of endocrine system Endocrine system include glands and the chemicals secretions secrete Inside Primary function: Growth, development and maintenance of body. 3 Open Stax Biology2e Endocrine vs nervous system 4  Hormones Lipid-Derived Hormones Amino Acid-Derived Hormones Peptide Hormones (or Lipid-soluble Hormones) 5  Hormones Peptide vs steroid hormones 6 Glands 7  Recall CNS Cerebrum Diencephalon Brain stem Cerebellum 8 Oopen Stax Biology2e  Pineal Gland Pineal gland 9 Hypothalamus Hypothalamus ▪ Produces releasing and inhibitory hormones Hypothalamic-pituitary axis 10  Pituitary Gland Pituitary Anterior pituitary produces hormones Posterior pituitary produces hormones 1. Growth hormone (GH), 1. Antidiuretic hormone (ADH) 2. Prolactin (PRL), 2. Oxytocin 3. Melanocyte-stimulating hormone (MSH), 4. Adrenocorticotropic hormone (ACTH), 5. Thyroid-stimulating hormone (TSH), 6. Follicle-stimulating hormone (FSH) 11 7. Luteinizing hormone (LH)  Thyroid Gland 12 By Drahreg01 - Own work, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=2688708 Thyroid gland+Parathyroid gland and calcium homeostasis Thyroid gland produces another hormone called Calcitonin If Calcium level inside increases then membrane permeability for sodium will____________. If Calcium level inside decreases too much then membrane permeability for sodium will____________. Parathyroid: Around the thyroid Produce parathyroid hormone that raises Calcium level 13  Adrenal Gland Each gland= Adrenal cortex and Adrenal medulla 14  Image reproduced in this slides has been included under ss. 29-29.4 of the Copyright Act.
