|
|
|
What types of collagen are most closely associated with basal lamina?
|
Collagen types 4 and 7.
|

|
How are connective tissue and basal lamina connected?
|
Anchoring fibrils (collage type VII) attach to reticular fibers.
Fibrillin attach to elastic fibers. |
|
|
Contrast focal adhesions and hemisdesmosomes.
|
Focal adhesions anchor the epithelium to the basal lamina through ACTIN (integrins and actin-binding linker prots).
Hemisdesmosomes anchor via intermediate filaments, using type 17 collagen and integrins. |
