Musculoskeletal Markers On The Shoulders - 1955 Words

MUSCULOSKELETAL MARKERS ON THE SHOULDERS By: Dustin Shinkle ANTH 3420 University of Northern Iowa Fall 2016 Abstract The purpose of this paper is to better inform the readers what stress markers are and what they are able to tell an anthropologist about a person. The reason that this is important is that it can help identify specific traits of how the person lived their life and a potential understanding of their work. In reading this paper you will hopefully have a better understanding how sex, age, and lifestyles can influence stress markers on bones of the shoulder joints. Introduction: Musculoskeletal stress markers can be found at the origin and insertion points of a muscle on a bone. These areas are known also as an enthesis. When using a muscle, a muscle will constrict and tighten, pulling at the origin and insertion point creating more blood flow to these areas so that they can create osteoblast as over time the bone that the muscle is attached to will diminish over time if not restructured. Over time the amount of osteoblast tends to dwindle creating more stress markers left on the bone. With this anthropologist, can approximate the age of an individual from the markings that were left behind. Anthropologist are also able to determine to an extent on the sex, weight, and other traits of the person they are analyzing. When it comes to sex of an individual studies have found that the stress marking in males tends to be greater in males than thatShow MoreRelatedResearch Achievements Of Construction Ergonomics1721 Words   |  7 Pagesdiscussed respectively.

Schrader’s research focused on entheseal changes and osteoarthritis in the skeletal remains found at Tombos, in an effort to understand how Nubian activity levels altered. The author used entheses, as a way of measuring musculoskeletal stress markers, and osteoarthritis to compare Tombos population (Schrader, 2012:62). Both conditions are impacted by the sex, age, and body size of an individual; along with environmental factors and genetic predispositions (Schrader, 2012:62).

Unfortunately, these chan ges can be seen in 64%–89% of asymptomatic patients.8-9 Similarly, shoulder MR imaging of asymptomaticRead MoreThe Influential Factors Of The Sit At Stand Movement Performance2363 Words   |  10 Pagesplaced on each side of the participants in the conditions of both high and both low. In contrast, the lower handrail height was set at the same level as subject’s center of balance in a sitting position, while the higher handrail height was on the shoulders level in both the conditions of high and low and reverse high and low. In the meantime, the heights of the handrails were also adjustable to fit each participant perfectly. Each participant was required to perform the five given types of STS movementRead MoreUnit 5 - P1,P2,P36290 Words   |  26 Pagessoluble. The fluid which surrounds the cells and the cytoplasm are watery environments next to the phosphate heads. Protein molecules create channels throughout the membrane to allow substances pass to and from the cell, they also act as identity markers for molecules such as hormones. This structure is also known as the ‘fluid mosaic model’ of the cell membrane.

Anatomy and Physiology of Musculoskeletal System The musculoskeletal system provides shape and support to the body, allows movement, protects the inner organs, produces red blood cells in the bone marrow (hematopoiesis), and stores calcium and phosphorus in the bones. Musculoskeletal system consists of three major components: bones, muscles, and joints. Tendons, ligaments, cartilage, and bursae serve asRead MoreThesis About Call Center Agents14127 Words   |  57 Pagesand socioeconomic status are also commonly asked. As outcome variables, studies commonly investigate health factors in relation to shift work. General, mental and reproductive health, health perception and condition, health complaints (e.g., musculoskeletal complaints, fatigue, and stress), health and safety hazards at work and nutritional status are examples of health factors investigated.
