Neuromuscular junctions of vertebrates are special types of chemical synapses formed from close association between motor neuron axon terminals and muscle fibers. A thin layer of basal lamina separates the two cell membranes at the neuromuscular junction and is important for its organization and maintenance. Which of the following would you NOT expect to find in the basal lamina in these structures?
A) Nidogen
B) Laminin
C) Type I collagen
D) Type IV collagen
E) Perlecan
