What happens to the membrane potential of OFF bipolar cells when photoreceptors are illuminated?arrow_forwardWhich of the following statements regarding the motor end plate in the somatic motor division of the nervous system is true? After the activation of voltage-gated calcium channels, the neuron releases ACh onto the muscarinic receptors on the surface of the highly folded area of the muscle fibre. The preganglionic nerve fibre releases ACh onto the postganglionic nerve fibre, which then releases ACh onto the cholinergic receptors of the motor end plate. Chemically gated monovalent cation channels on the motor end plate are activated once the motor neuron releases ACh onto the nicotinic receptors on the surface of the muscle cell. The AChE enzyme enhances the amount of ACh released into the neuromuscular junctionarrow_forward
