Describe an excitatory cholinergic synapse
WebSynapses Where two neurons meet there is a small gap called a synapse. The plasma membranes of each neuron are in very close contact and are separated by a narrow space called a synaptic cleft.... WebThe focus of this chapter is on these chemicals, what they are, how they are released, and how they can alter cell physiology. In this chapter, we will explore the process of neurotransmission: how it was discovered, how it works, and how drugs can interact with the process. We will then cover several neurotransmitters and receptors to see ...

WebA cholinergic neuron is a nerve cell which mainly uses the neurotransmitter acetylcholine (ACh) to send its messages. Many neurological systems are cholinergic. Cholinergic neurons provide the primary source of acetylcholine to the cerebral cortex, and promote cortical activation during both wakefulness and rapid eye movement sleep. [1] WebWhile the autonomic nervous system is in charge of involuntary functions like digestion, respiration, and heart rate control, the somatic nervous system is in charge of voluntary …
