Identify the exact location in a cholinergic synapse that each statement refers to: • a region with many mitochondria; • a region where ACh is released by exocytosis; • a region containing voltage-gated channel proteins; • a region containing ligand-gated channel proteins.
Outline the functions of synapses in the nervous system.
Some insecticides include compounds known as organophosphates. In neuromuscular junctions, organophosphates can act as enzyme inhibitors. People who use organophosphates and do not obey safety guidelines are at risk of organophosphate poisoning, which disrupts muscle function. Suggest how organophosphates could affect muscle function in humans.
Outline the function of the sarcoplasmic reticulum in striated muscle contraction.
