Explanation:
The is the sequence of action potential transmission at at the neuromuscular junction. Generally the arrival of action potential from the presynptic neuron caused influx of ca+ which causes migration and the release of the the acetycholine to the synaptic cleft.
The acetycholine binds with the receptors on the saccolemma to causes opening of Na+ , its influx to causes depolarizarion of the sacolemma. The depolarization of the latter spreads along the transverse tubules, This depolarization causes increases in the permeability of the sacorplasmic reticulum, with opening of ca+ channels and diffusion of Ca+ out of the S. reticulum.
The Ca+ binds to troponin,and tropomyosin exposed the myosin-binding sites on actin filament . The myosin head forms the cross bridges with the filament, and therefore the sacomere shortens leading causing muscle contraction.
Answer:
As blood flows through the glomerulus, blood pressure pushes water and solutes from the capillaries into the capsule through a filtration membrane. This glomerular filtration begins the urine formation process.
