What are the structural and cellular features of a hair follicle?
The structural and cellular features of a hair follicle include the papilla, root sheath, matrix, bulge, and hair fiber. The arrector pili is another hair structure that is a very small muscle fiber attached to the follicle.

Do any human have hollow hair?
Yes, some humans have hair that can be described as hollow. This is primarily seen in individuals with certain types of hair, such as fine or thin hair, where the hair shaft may have a less dense structure, leading to a hollow appearance. Additionally, certain genetic conditions can lead to variations in hair structure. However, the concept of "hollow hair" is not common in typical discussions about human hair.
Is human hair hollow?
No, human hair is not hollow. Each hair strand is made up of a protein called keratin and has a structure that includes three main layers: the cuticle, cortex, and medulla. The medulla, which is the innermost layer, may be present in some hair types but is not hollow; it consists of loosely packed cells. Overall, hair is solid and not a hollow structure.
Which structure of the human ear is filled with fluid and lined with tiny hair lines?
The cochlea is the structure of the human ear that is filled with fluid and lined with tiny hair cells. These hair cells are responsible for converting sound vibrations into electrical signals that are then sent to the brain for processing.
What are 3 reasons hair makes good evidence?
Hair contains DNA which can be used for identification purposes. Different individuals have unique hair characteristics such as color, texture, and structure, making it possible to differentiate between individuals. Hair is resistant to decomposition and can be found at crime scenes, providing valuable forensic evidence.
What human hair can be be distinguished from an animal hair by examining?
Human hair can be distinguished from animal hair by examining the medulla, which is the central core of the hair. In human hair, the medulla is often absent or very thin, while in many animal hairs, it is typically wider and more pronounced. Additionally, the cuticle pattern and the overall thickness of the hair can provide further clues; human hair usually has a more uniform diameter and a different scale structure compared to animal hair.
Does a human have fur?
Humans do not have fur; instead, they have hair. While fur typically refers to the dense coat of soft hair found on many animals, human hair is generally thinner and grows in varying lengths and textures. Human body hair is less dense and serves different functions, such as providing some insulation and sensory feedback. Overall, the structure and purpose of human hair differ from that of animal fur.
Why is human hair strong?
Human hair is strong due to its structure, which consists of a protein called keratin. This protein forms a network of fibers that provides strength and elasticity to the hair shaft. Additionally, the outer layer of the hair, known as the cuticle, helps protect the inner layers and contributes to the overall strength of the hair.
