  1. The Endocrine System Structures The endocrine system has many structures. All of the structures include certain horomones. Certain structures include certain horomones.

  2. List of structures. Part 1 • Structures include • Hypothalamus, • Pineal Body, • Pituitary gland , • Thyroid, • Stomach, • Duodenum, • Liver, • Pancreas,

  3. List of structures. Part 2 • Kidneys, • Adrenal glands, • Testes, • Ovarian follicle , • Corpus luteum, • Placenta (when pregnant), • Uterus (when pregnant), • Parathyroid, • Skin, • Heart, • Bone marrow, and • Adipose tissue.

  4. This system has 3 signaling types. Signals include Autocrine, Paracrine, and Juxtacrine.

  5. Autocrine Signaling The Autocrine is a form of signaling in which a cell secretes (Generate) a hormone, or a chemical messenger that binds the autocrine receptors to the same cell, leading to changes to the cell.

  6. Paracrine Signaling Paracrine signalling is a form of cell signalling in which the target cell is near ("para" = near) the signal-releasing cell.

  7. Juxtacrine Signaling Juxtacrine signalling is a type of intercellular(situatedbetweenoramong cells) communication that is transmitted via oligosaccharide(carbohydrate), lipid(organic compounds that are greasy), or protein components of a cell membrane, and may affect either the emitting cell or the immediately adjacent cells.

  8. There are also 2 different types of feedbacks, Positive and negative

  9. Negative Signaling The stopping of the synthesis of an enzyme by the accumulation of the products of the enzyme-mediated reaction.

  10. Positive Feedback Biochemical control where the accumulation of the product stimulates production of an enzyme responsible for that product's production.
