Final answer:
The statement that all men and women have about the same number of hair follicles spread throughout their thin skin is true. The average number of hair follicles for adults is around 5 million, with most of these being on thin skin, which is thinner than glabrous skin.
Step-by-step explanation:
The statement that ALL men & women have about the same number of hair follicles spread throughout their thin skin is True. It is generally accepted that adults have approximately the same number of hair follicles spread across their bodies, regardless of gender.
On average, humans have about 5 million hair follicles, with the density of hair follicles varying on different parts of the body. The majority of these follicles are located on thin skin, which is not as thick as glabrous skin.
For example, glabrous skin, like the skin on human fingertips which does not contain hair follicles, is typically 4 to 5 mm thick, whereas the hairy skin elsewhere is 2 to 3 mm thick. It is noteworthy that specialized structures like sebaceous glands and arrector pili muscles are associated with hair follicles.
