grow older‚ muscles may lose their density‚ flexibility and tone. Ossification is the process by which bones are formed and there are two types of bone formations. According to our Wiley textbook “Intramembranous ossification‚ one of the types of bone formations‚ happens when osseous tissue forms directly within mesenchyme arranged in sheet like layers that resemble membranes. In the second method‚ endochondral ossification‚ osseous tissue forms within hyaline cartilage that develops from mesenchyme

Fibrodysplasia ossificans progressiva (often called FOP‚ or Stone Man’s Disease) is an incredibly rare disease that directly affects the patients connective tissue. The name means “soft connective tissue that progressively turns to bone.” FOP is a result of a mutation in the body’s tissue repair structures‚ which will cause fibrous tissue to turn to bone‚ or become ossified‚ randomly or upon tissue damage. In the majority of cases‚ any injury can cause the affected joints to become frozen in place

Maceration Techniques and Methods The interest in maceration‚ in the anthropological perspective‚ began in the 19th century. Over the following century the largest ambitious endeavor was the maceration of thousands of individuals‚ this collection is known as the Hamann-Todd Collection (Dawnie 11). Maceration according to the Merriam-Webster Dictionary is‚ “to cause to become soft or separated into constituent elements by or as if by steeping in fluid”. Maceration is a form of controlled putrefaction

Unit 32 Factors affecting growth and repair M1 In this assignment I am going to explain the factors that might affect the growth and repair of bones. There are many different factors that can affect the growth and repair of the bones I am going to explore 4 factors and these are; * Exercise: Doing regular exercise helps build the muscle’s in the body‚ but it also helps maintain the bones and increase the bones strength. Exercise causes the muscle to contract against the bone. This action then

1. Describe Ossification during Fetal Development. Ossification is the formation of bone and in a fetus is made up of cartilaginous tissue. This tissue is less dense than that of bony tissue. Over time‚ as calcium salts are being deposited into the cartilaginous tissue by immature bone cells‚ the formation of bone occurs. 2. What are the roles of Osteoclasts in bone formation? Osteoclasts reabsorb bony tissue from the innermost part of the bones‚ allowing for a larger cavity‚ in order to avoid

Odontogenisis The origin or the development of the tooth and tissue formation is known as Odontogenisis. The formation of the tooth begins at six weeks in the human embryo. However not all tooth develop at the same time. Although Odontogenisis is a continuous process it is divided into various stages. These stages are Bud stage‚ Cap stage and Bell stage which is followed by root formation and eruption. The basal layer of the ectoderm which is derived from the oral epithelium at the stomadeum

Lab 34-2: 1. The general trend for bone density as a person ages is a steady decline as years pass. This study shows that every decade‚ males and females bone density slowly decreases. 2. Between the ages of 20-50 females lose about 11% of their bone density and males lose about 13% of their bone density. Males do in fact lose more density then females but they lose it at a more stable and steady rate. Females lose less density at more unstable rate going from about 6% (40-50) to about 9%

If a human femur was found‚ for example buried in a forest‚ a forensic anthropologist will need to examine it. However‚ if more bones were found there may be a more useful bone‚ or combination of bones‚ that would be more likely to provide pertinent information. There are many things that can be found out from a human femur‚ when it is first found and proved to be human anthropologists can use different observations‚ measurements and analysis techniques to categorise the bone and build up a biological
