• 45 Hormones and the Endocrine System

• What is a hormone and what does it do?

  A hormone is a molecule that is secreted into the extracellular fluid, circulates in the blood or hemolymph, and communicates regulatiry messages throughout the body.

• The circulatory system of the body allows hormones to reach all cells of the body, so is it able to influence every cell of the body?

  No, because only the target cells have receptors that react to the hormone and enable a response.

• 45.1 Hormones and other signaling molecules bind to target receptors, triggering specific response pathways

• What types of signaling molecules are distinguished?

  • Hormones
  • Local regulators
  • Neurotransmitters and Neurohormones
  • Pheromones

• What types of intercellular communication by secreted molecules are distinguished?

  • Endocrine signaling
  • Paracrine signaling
  • Autocrine signaling
  • Synaptic signaling
  • Neuroendocrine signaling

• 45.1.1 types of secreted signaling molecules

• How do signaling molecules trigger responses?

  By binding to a specific receptor protein in or on target cells

• What is the difference between asexual and sexual reproduction?

  In sexual reproduction offspring is created by the fusion of a male and a female gamete, in asexual reproduction offspring is created without the fusion of male and female gamete.

• What possible ways are there to reproduce asexually?

  • fission
  • budding
  • fragmentation and regeneration
  • Partheogenesis

• What possible ways are there to reproduce sexually?

  • Internal fertilization
  • external fertilization

• Describe what fission is

  Fission is an asexual reproduction form where the parent organism seperates into two induviduals of approximately the same size.
