PKMzeta inhibits a critical pathway in the amygdala which appears to block the establishment of painful memories. Structure: There are two amygdalae in the human brain - one in the temporal lobe of each hemisphere. The amygdalae are connected by the anterior commissure‚ one of the three major pathways for information to leave the amygdala. The other

The Endocrine System FOCUS: The endocrine system is one of the major regulatory systems in the body‚ along with the nervous system. However‚ the endocrine system responds more slowly‚ and has a longer-lasting‚ more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability
