The medullary index is a ratio used in anthropology and forensic science to compare the width of the medullary cavity (the inner, hollow part of a bone) to the overall width of the bone itself. It is calculated by dividing the diameter of the medullary cavity by the total diameter of the bone at a given cross-section. This index can help differentiate between species or determine characteristics of skeletal remains, as variations in this ratio can indicate different adaptations or developmental conditions. Generally, a higher medullary index suggests a more robust bone structure.

What is difference between sparse index and dense index?
Dense Index: An index record appears for every search key value in file. This record contains search key value and a pointer to the actual record. Sparse Index: Index records are created only for some of the records. To locate a record, we find the index record with the largest search key value less than or equal to the search key value we are looking for. We start at that record pointed to by the index record, and proceed along the pointers in the file (that is, sequentially) until we find the desired record. - - (ref: http://sawaal.ibibo.com/computers-and-technology/difference-between-sparce-index-dence-index-773764.html)

How can we use the diameter to calculate the medullary index?
The medullary index is calculated by comparing the diameter of the medullary cavity to the diameter of the entire bone. To find the medullary index, you divide the diameter of the medullary cavity by the total diameter of the bone and then multiply the result by 100 to express it as a percentage. This index helps assess the relative size of the medullary cavity in relation to the overall bone structure, which can be useful in fields like anthropology and forensic science.
Which medullary index indicates an animal hair?
The medullary index is a measurement used to differentiate between types of hair. In animal hair, the medullary index is typically greater than 0.5, indicating a wider medulla relative to the diameter of the hair shaft. In contrast, human hair usually has a medullary index of less than 0.33. Therefore, a medullary index greater than 0.5 suggests the hair is from an animal.
How is the medullary index of hair calculated?
The medullary index measures the diameter of the medulla relative to the diameter of the hair shaft. MI= Medulla Diameter -------------------------- x 100 Hair Diameter
Which factors are used to calculate the medullary index of the hair?
The medullary index of hair is calculated by comparing the diameter of the medulla (the central core) to the diameter of the entire hair shaft. Specifically, the formula is: Medullary Index = Diameter of Medulla / Diameter of Hair Shaft. This index helps in distinguishing between different types of hair, as it varies among species and can indicate whether the hair is from a human or an animal.
What medullary index is commonly considered to indicate a human hair?
usually it's 0.33 or less...
What is the medullary index of a human hair?
The medullary index of human hair is typically less than 0.33, which means that the diameter of the medulla is less than one-third of the diameter of the entire hair shaft. Human hair generally has a solid or absent medulla, making it distinct from the hairs of many other animals that may have a more pronounced medullary structure. This characteristic is often used in forensic science for hair identification and comparison.

What is medullary?
Medullary (myelin)- sheath is the covering of nerve fibres. It insulates the nerve fibre (axon) and prevents leakage of ions.
Meaning of medullary?
The word medullary refers to a part of the body or an organ that resembles bone marrow, such as dorsally located tissue.
