Excitation-contraction coupling refers to the events that link the action potentials on the sarcolemma to activation of the . it begins with the arrival of the at the neuromuscular junction.

Excitation-contraction coupling refers to the events that link the action potentials on the sarcolemma to activation of the Ca+ channels . It begins with the arrival of the action potential at the neuromuscular junction.

Explanation:

The action potential travels from the neuron and it is transmitted to the muscle through the neuromuscular junction, which is the place where the neuron and the muscle join. Once that the action potential is in the muscle this will open Ca+ channels in order to let the Ca+ enter the muscle fiber and produce the contraction in the sarcomere.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
