Psychopharmacology 3e Chapter 3 Outline
Chemical Signaling by Neurotransmitters and Hormones
Chemical Signaling between Nerve Cells
Neurotransmitter Synthesis, Release, and Inactivation
Neurotransmitters encompass several different kinds of chemical substances
Box 3.1 Clinical Applications
Orexin-Based Medications: New Approaches to the Treatment of Sleep Disorders
Neuropeptides are synthesized by a different mechanism than other transmitters
Neuromodulators are chemicals that don’t act like typical neurotransmitters
Classical transmitter release involves exocytosis and recycling of synaptic vesicles
Lipid and gaseous transmitters are not released from synaptic vesicles
Several mechanisms control the rate of neurotransmitter release by nerve cells
Neurotransmitters are inactivated by reuptake and by enzymatic breakdown
Neurotransmitter Receptors and Second-Messenger Systems
There are two major families of neurotransmitter receptors
Second messengers work by activating specific protein kinases within a cell
Tyrosine kinase receptors mediate the effects of neurotrophic factors
Pharmacology of Synaptic Transmission
Synaptic Plasticity
The Endocrine System
Endocrine glands can secrete multiple hormones
Mechanisms of hormone action vary
Why is the endocrine system important to pharmacologists?
Box 3.2 Pharmacology in Action
Sex Hormones and Drug Abuse
