How do the basal lamina and basement membrane differ in their structure?
How do the basal lamina and basement membrane differ in their structure?
- The basal lamina is thinner and more electron-lucent than the basement membrane
- The basal lamina is visible only under an electron microscope, while the basement membrane is visible under a light microscope (correct)
