The Endocrine System Structures

The endocrine system has many structures. All of the structures

include certain horomones. Certain structures include certain horomones.

  • Structures include
  • Hypothalamus,
  • Pineal Body,
  • Pituitary gland ,

  • Kidneys,
  • Adrenal glands,
  • Testes,

  • Corpus luteum,
  • Placenta (when pregnant),
  • Uterus (when pregnant),
  • Parathyroid,
  • Skin,
  • Heart,
  • Bone marrow, and
  • Adipose tissue.

This system has 3 signaling types. Signals include



and Juxtacrine.


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.

paracrine signaling
Paracrine Signaling

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

juxtacrine signaling
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.

negative signaling
Negative Signaling

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

positive feedback
Positive Feedback

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