Other unconventional messengers will probably be discovered as we learn more and more about how neurons work as these new chemical messengers are discovered, we may have to further change our idea of what it means to be a neurotransmitter. Brainscape uses an adaptive learning algorithm that we call confidence-based repetition our platform is scientifically proven to help you learn faster and remember longer.

At the synapse, the firing of an action potential in one neuron—the presynaptic, or sending, neuron—causes the transmission of a signal to another neuron—the postsynaptic, or receiving, neuron—making the postsynaptic neuron either more or less likely to fire its own action potential.
Chemical messengers comprehensive notes on the endocrine system and it's role in maintaining homeostasis includes: • definitions • hormones - target cells/organs & main effects • endocrine glands - their location, hormone secreted, hormone effect & target cells/organs studied in year 12 atar human biology. Human biology 3a notes chapter 4: chemical messengers homeostasis:the maintenance of a constant internal environment homeostasis ensures that the fluid environment of the cells: • contains the optimum concentration of nutrients, ions, gases and water • stays at a constant temperature – the optimum temperature for normal cell functioning • is maintained at the optimum.
The study of biology includes the study of human beings the biological functions of humans are similar to those of many other animals like other animals, humans need to acquire oxygen and energy in order to survive hormones are chemical messengers that can alter the behavior of target cells the nervous system consists of two main.
