Depression is a condition in which sufferers may feel low mood, lack of motivation and sleep. It is caused by a lack of serotonin in the synaptic cleft of neurone pathways. Serotonin is a neurotransmitter. a) Describe how serotonin acts as a neurotransmitter. Using your understanding of synaptic transmission, explain how communication between neurones in serotonin pathways of the brain would be affected in someone with depression. b) Doctors use tubocurarine drug as an anaesthetic as it temporarily paralyses muscles. It blocks receptors at neuromuscular junctions. Why does this lead to paralysis?
