How do pubic hairs differ from hair found on other parts of the human body? Hairs from the legs and arms. Shorter in length, arc-like in shape, and often abraded or tapered at the tips.
Human hair has cuticle scales that are flattened and narrow, also called imbricate. Animal hair has different types of cuticles that are described and pictured later in the chapter under animal hair. In humans, the cortex is the largest part of the hair shaft.Oct 2, 2010

What are the three medulla patterns?
When the medulla is present in human hairs, its structure can be described as fragmentary or trace, discontinuous or broken, or continuous. Figure 95 is a diagram depicting the three basic medullary types. The cortex is the main body of the hair composed of elongated and fusiform (spindle-shaped) cells.
Which of the following are types of hair scale forms found in the cuticle?
There are three basic scale structures that make up the cuticle—coronal (crown-like), spinous (petal-like), and imbricate (flattened). Combinations and variations of these types are possible. Figures 85-90 illustrate scale structures.

What are the medulla patterns?
It is the same protein that makes horn, fingernails, claws, skin epithelium, and dander. Mammalian hair consists of three distinct morphological units, the cuticle, the cortex and the medulla. The distinctive pattern shown by these units varies over the length of the hair in a way that can be very characteristic.
What is the purpose of the medulla in hair?
The medulla is the innermost layer of the hair shaft. This nearly invisible layer is the most soft and fragile, and serves as the pith or marrow of the hair.
