Description
Chapter 8: Synaptic Transmission and neural Integration Morphine a product of opium poppy relieves pain because it can bind to certain neurons in a CNS at receptors for naturally occurring morphine like messenger molecules- Enkephalins and Endorphins. Thus morphine suppresses the transmission of pain signals. Chemical messenger acts by binding to a receptor. NT bind to postsynaptic neuron. 2 Types of synapse in Nervous System: 1. Electrical synapses via gap junctions that link two cells electrically (by electrical signals) 2. Chemical Synapses - synapse where a neuron secretes a neurotransmitter (activate signal transduction mechanism ) into the extracellular fluid in response to an action potential arriving at the axon terminal Electrical Synapses Exist bet. Neurons and bet. Neurons and glial cells. Plasma membrane of adjacent cells are linked by gap junctions Junctions transmit signal in the adult brain Co
