Signals

signal transduction

Much of human physiology involves either

1) extracellular signaling molecules that function as hormones, neurotransmitters, growth factors etc. or

2) intracellular signal transduction mechanisms.

This page has a list of signals and signaling pathways that are discussed in blog posts:

• • Hedgehog pathway
  • light
  • Wnt signaling
  • Notch signaling
