- AMelanocytes
- BCyanosis
- CKeratinocytes

10The superficial ___(A)___ consists of LOOSE CONNECTIVE TISSUE tissue. This region contains the CAPILLARIES supplying the epidermis and the NERVE AXONS of sensory neurons that monitor receptors in the papillary layer and the epidermis.
- APapillary layer
- BReticular Layer
- CBasale Layer
- DSurface Layer
11The ___(B)___ consists of fibers in an INTERWOVEN NETWORK of dense irregular connective tissue that surrounds blood vessels, HAIR FOLLICLES, nerves, SWEAT GLANDS, and SEBACEOUS GLANDS. The name of the layer derives from the interwoven arrangement of collagen fiber bundles in this region

- APapillary Layer
- BReticular Layer
- CBasal Layer
- DSurface Layers
13The interwoven collagen fibers of the reticular layer: (Check all that apply)
- ARecoil repeatedly during normal movements
- BThe extensive array of elastic fibers enables the dermis to stretch and
- CProvide considerable tensile strength
- DProvide a degree of water resistance

15The extensive distortion of the dermis that occurs over the abdomen during pregnancy or after a substantial weight gain often exceeds the elastic capabilities of the skin. Elastic and collagen fibers then break, and although the skin stretches, it does not recoil to its original size after delivery or a rigorous diet. The skin then wrinkles and creases, creating a network of [blank_start]stretch marks[blank_end]
