In human beings arguably two of the most important structures in the human body are the spine and the spinal cord. The function of the spine is to protect the spinal cord, provide structural support and balance whilst helping maintain an upright posture and also allow flexible body motion. The function of the spinal cord is to conduct information. This involves sensory information from the peripheral nervous system to the brain, and then motor information from the brain to a range of effectors including muscles and glands (Users.rcn.com, 2016).The spinal cord forms part of the central nervous system, so damage to the spinal cord can have sever...

...lso form parts of the myelin sheath (Orth and Bellosta, 2012). The lipid properties of cholesterol means that it can carry out its function in neurones and support the work of the spinal cord, and central nervous system.
To conclude, it is shown that from a molecular level, i.e. Cholesterol all the way up to the body system level, i.e. the central nervous system, structure and how it relates to the function is vital in making sure an organism survives and everything is working efficiently. It can also be shown in other species and also in plants, i.e. with chloroplasts which are structured to allow photosynthesis within a plant. Then within this organelle are smaller and smaller structures all specifically, all the way down to the molecular level with genes coding for specific enzymes which has all evolved to allow a whole system to work efficiently and effectively.

- The overall purpose of the experiments in this lab was to introduce the function and structure of the plasma membrane, describe the workings of diffusion and osmosis, and to demonstrate how different factors such as particle size, temperature, and space of diffusion area affect the rate of diffusion. With the results from the experiments, it can be concluded that all of the factors listed do affect diffusion, and there may be many more than are unaccounted for. Through the osmosis experiment, it was clear that water moved into the cell due to a lack of water and an excess of solute; in the environment, there was an excess of water and a lack of solute....

- Heart disease the driving force behind the death rate in the United States, also ranking first among both genders (The Heart Foundation, 2015). Take control of your health conditions and make healthy choices on what your body consumes can help reduce your chances of developing heart disease. However, people of the community and families can cooperate to the contingency of the people to make better health choices. The duties of public health officers perform at numerous levels from regional to national, to international.... [tags: Public health, Health care, Health, Medicine]

- Proteins are considered to be the most versatile macromolecules in a living system. This is because they serve crucial functions in all biological processes. Proteins are linear polymers, and they are made up of monomer units that are called amino acids. The sequence of the amino acids linked together is referred to as the primary structure. A protein will spontaneously fold up into a 3D shape caused by the hydrogen bonding of amino acids near each other. This 3D structure is determined by the sequence of the amino acids....

- ... The backbone of the nucleic acids consists of the interaction between phosphate groups and the hydroxide groups of nucleic acids. These are held together by covalent bonds called phosphodiester bonds. The helix itself is held together by hydrogen bonds. Although hydrogen bonds are weak individually, there are so many of them within DNA that the strands are held tightly together. Without basic chemistry the structure of DNA would be a mystery. The instructions to make a protein are coded by DNA.... [tags: function, protein, products]

- Life itself would be entirely impossible without proteins. There are so many types of protein and every protein has a unique job or function, some of these include giving shape and structure to cells, message carrier, enzyme promoters and some proteins even act as hormones, elastic fibers, and even antibodies (Albert al et., 2013,120). However, proteins obtain these functions due to the shape each protein adopts. There are four different levels a protein structure can adopt, these include primary, secondary, tertiary, and quaternary, these can be seen in figure 1....

- The kidneys play key roles in body function not only by filtering and getting rid of waste products but also by balancing the electrolyte levels in the body, controlling blood pressure and stimulating the production of red blood cells. As the kidneys filter blood, they create urine which collects in the kidney’s pelvis funnel shaped structure that drain down tubes called ureters to the bladder. The kidneys are located in the abdomen towards the lower back. Each kidney is about 4 or 5 inches long about the size of a fist.... [tags: Kidney, Nephrology, Chronic kidney disease]

- Discussion: Our preliminary hypothesis was that the Chlamydomonas cells exposed to actinomycin D would show slow regeneration of the flagella compared to the control, or no regeneration of the flagella. This hypothesis was based on researching the structure and function of actinomycin D. structurally, actinomycin D is a cromopeptide, which consists of a phenoxazone ring and two cyclic pentapetides. The two cyclic pentapetides contain polar, uncharged amino acids such as threonine and proline and the phenoxazone ring contains N-H hydrogen bond and a free, nucleophilic oxygen (Hughes, 2009)....

- Psychopathic Brain Function According to the Federal Bureau of Investigations website, psychopathy has been described as the single most important clinical construct in the criminal justice system. It goes on to say that the need to understand psychopathy cannot be overstated (FBI, 2013.) From environmental influence to biology, psychopathy can be looked at from several different angles. This paper examines current thinking about how the brain and its structures contribute to psychopathy. One area of research in psychopathy focuses on the set of structures in the brain known as the limbic system, but more specifically on a structure known as the amygdala....

- "In everyday language usage, management refers to the people in organizations who manage, and to the activities they perform." (Fulop, Frith, Hayward 1992 p. 187) To be more specific, management is the process of organizing work activities with and through people to ensure the activities are completed efficiently and effectively (Robbins, Bergman, Stagg, Coulter 2006, p. 9). Through management, the goals of the organization or business are to be achieved. Henri Fayol, one of the most influential contributors to modern concepts of management, proposed that there are five primary functions for management, which consist of planning, organizing, commanding, coordinating and controlling....

- ORGANIZATIONAL STRUCTURE Organizational structure refers to the way that an organization arranges people and jobs so that its work can be performed and its goals can be met. When a work group is very small and face-to-face communication is frequent, formal structure may be unnecessary, but in a larger organization decisions have to be made about the delegation of various tasks. Thus, procedures are established that assign responsibilities for various functions. It is these decisions that determine the organizational structure.... [tags: Business Company Management ]
