  1. 1. THE ENDOCRINE SYSTEM
  2. 2. Concept 45.3 The endocrine and nervous systems act individually and together in regulating animal physiology Coordination of Endocrine and  A prominently known gland the Nervous Systems in pituitary gland is often known Invertebrates as the “master” gland of the All animals except the simplest endocrine system. This is so invertebrates reproduction and because it controls the main development are controlled by functions of all other glands. the endocrine system.  The pituitary gland has 2 lobes For example in a molting the posterior and anterior insect, a peptide pituitary. Both of which secrete neurohormone from the insects different hormones. endocrine  posterior= Oxytocin and system, PTTH, promotes each antidiuretic hormone. successful molt until it reaches  Anterior= the final stage. prolactin, adrenocorticotropic Most hormonal glands are hormone, thyroid-stimulating located in the brain of the hormone, follicle-stimulating animal. hormone, luteinizing hormone

  4. 4. Concept 45.4 Endocrine glands respond to diverse stimuli in regulating metabolism, homeostasis, development, and behavior Thyroid : consists of lobes on the ventral side of the trachea. Thyroid hormone refers to a pair of similar hormones known as Triiodothyronine(T3) and Thyroxine(T4), which have corresponding iodine atoms T3 has 3 and T4 has 4. The thyroid mainly produces T4 atoms in humans but the body changes them to T3 because iodine is dedicated to the production of the Thyroid hormone. Also a dietary iodine is a must. This may be ingested by eating seafood or iodized salts with out this dietary iodine goiter may occur which is a swelling in the neck.
  5. 5. Glands Con’t Parathyroid glands regulate  Adrenal glands are the release of calcium into the associated with the kidneys. body.  Made up of two parts, the Unregulated release of outer part known as the calcium can result in organ adrenal cortex, and the damage. central portion known as the adrenal medulla.  The adrenal gland also plays a role in releasing adrenaline (also known as epinephrine) when the body senses danger or is excited.
  6. 6. Sex Hormones Sex hormones affect growth, development, and reproductive cycles. The gonads produce three hormones which are all produced in both genders just in different proportions, androgens, estro gens, and testosterone. Testosterone is more prominent in males hence the deeper tone of voice. Estrogen is more prominent in females hence larger breasts and a higher pitched voice
