How would you explain to your roommate, who has NEVER taken an A&P class, why a superficial paper cut to his index finger did not bleed? the superficial layers of the epidermis have fewer blood vessels than deeper epidermal layers, the paper cut passed through the dermis, which is avascular and contains no blood vessels, epidermis, the top layer of the skin, is epithelial tissue and has no blood vessels, blood vessels are only located in the hypodermis

epidermis, the top layer of the skin, is epithelial tissue and has no blood vessels

Which of the following is NOT a function of the skeletal system? temperature maintenance storage of minerals leverage support

temperature maintenance

Which of the following is NOT a type of tissue membrane? Apocrine Synovial Mucous Cutaneous

Apocrine

Why would the ink of permanent tattoos be deposited in the dermis, and not the epidermis of the skin? The ink needles are too long; they can only penetrate through to the dermis.The dermis is thicker than the epidermis.The tattoo ink only bonds with connective tissue.The epidermis is continually replaced by new cells as old cells are shed.

The epidermis is continually replaced by new cells as old cells are shed.

Since the epidermis is avascular, how do the epidermal cells obtain their nutrients? the cells of the epidermis are capable of synthesizing their own nutrients, from the blood vessels in the adjacent dermis, the cells of the epidermis are dead; they do not require nutrients, from the blood vessels of the basement membrane

from the blood vessels in adjacent dermis
