The following points highlight the five main types of receptors found in animals. The types are: 1. Intracellular Receptors 2. Cell Surface Receptors 3. G-Protein Coupled Receptors 4. Ion-Channel Receptors 5. Tyrosine Kinase Linked Receptors. Type # 1. Intracellular Receptors: Steroid hormones, thyroxin and retinoids are lipophilic and are transported by carrier proteins in the […]
Here is a list of seven main hormones found in animals. They are: 1. Progestins 2. Antiprogestins 3. Luteolytics 4. Thyroid Hormones 5. Parathormone 6. Calcitonin 7. Insulin. Hormone # 1. Progestins: Progesterone is naturally secreted from corpus luteum. It is also secreted from Placental cells in some species like horse, sheep, dog and cat […]
There seem to be many factors concerned in regulation of secretion of hormones. They are: 1. Influence of Higher Centres 2. Feed-Back Mechanism 3. Peripheral Nervous Control 4. Genetic Control. Factor # 1. Influence of Higher Centres: Higher centres of brain under influence of environmental factors regulate the secretion and release of various hypothalamic hormones, […]
