Final answer:
The statement is true; vellus hair is typically not pigmented and almost never has a medulla, which differentiates it from the coarser and pigmented terminal hair.
Step-by-step explanation:
The statement that vellus hair is not pigmented and almost never has a medulla is True. Vellus hair is a type of hair that is typically short, fine, and light-colored, to the point of being translucent and sometimes entirely unpigmented. It is different from terminal hair, which is coarser, darker, and longer. Vellus hair is often referred to as 'peach fuzz' and is found on many areas of the body. It lacks a medulla, which is the central core of the hair strand found in terminal hair, and does not typically have pigment, meaning it doesn't have a significant amount of melanin.
