When an action potential arrives at the end of the axon terminal, a series of events take place that result in the release of neurotransmitter from the presynaptic axon. Select the answer that correctly describes the primary stimulus for vesicles to move toward the cell membrane and eventually release their contents. ? View Available Hint(s) Voltage-gated channels open, and $K^+$ exits to the extracellular fluid, decreasing intracellular $K^+$. Voltage-gated membrane channels open, and multiple types of ions enter the cytoplasm, increasing the intracellular positive charge. Axonal $Ca^{+2}$ is increased because endoplasmic reticulum voltage-gated calcium channels open and $Ca^{+2}$ enters the cytoplasm. Voltage-gated membrane channels open, and $Ca^{+2}$ enters the cytoplasm, increasing intracellular calcium.

Q3. A rectangular coil having sides 4 cm and 6 cm lies in a plane and consists of 100 turns of wire carrying a current of 5 A. A long straight wire carrying a current of 2 A lies in the same plane as the coil parallel to and 4 cm from the nearest long side, such that its current, and the current of the closest side, are in the same direction. Calculate the force on each side of the coil from the straight wire, and hence find the total force on the coil. You can leave your answers expressed as a function of $\mu_0$. [10 Marks]
