Corrugator supercilii muscle

described as decline or regression in body ability to adapt to physical insults and environmental stressors. And that is because of the physiological changes associated with aging like decrease in muscle and bone mass, decreased vital capacity of lungs and decreased nerve conduction velocity.…

Chordate Dissection and Anatomy In this lab, a dissection was performed on a mouse, a frog, and a dogfish shark, and the anatomy was observed and noted. The three animals have some similarities and differences. The mouse, frog, and dogfish shark are all similar in that they all have closed circulatory systems. But the three animals have different types of hearts. The mouse has a four chambered heart, the frog has a three chambered heart, and the dogfish shark has a two chambered heart. The…

Exercise benefits people in many ways from physical to mental health. With the health conscious society we live in, there are more people now than ever that look to daily exercise to maintain overall health. It has been used to battle childhood obesity, increase energy levels as well as improve heart health. The versatile benefits of exercise has caused it to become a recent trend. Childhood obesity is a major problem in the United States due to the availability of junk food as well as the lack…

motor neurons meet at the same effector muscles. Furthermore, when the extrafusal fibers of the muscle spindle contract, the intrafusal fibers change length in correlation to the muscle tone to activate the feedback to the brain, which is done by the gamma neurons. The feedback process is performed by afferent neurons located in the spinocerebellar tract, in which they relay the message to the central nervous system regarding the length and tension of the muscle fibers.…

This single critical condition has claimed the lives of 287,000 people each year everywhere from the age of an infant to the age of your current peers to the age of the elderly (Heart Failure Statistics, 2016) . There are about 5.1 million people in the United States alone that suffer from this serious, possibly fatal, condition and die within five years of diagnosis (Heart Failure Fact Sheet, 2015). Not to mention, 1.4 million people under the age of 60 years old have this condition, and as a…

fitness components because it is able to determine acceleration, maximum running speed and speed endurance. However these aspects vary depending of the distance tested over. Vertical jumps tests are effective when testing the strength of the leg muscles as you are required to jump as high as you can from the push from your legs. In order to reach the fitness goals and improve and maximise test results, at least four to five training sessions need to be implemented to achieve noticeable results.…

smoothly, decreasing the risk of cardiovascular diseases. Not only can physical activity help prevent heart problems but it can also prevent type two diabetes, certain types of cancers, metabolic syndrome, and arthritis. Regular activity can improve muscle strength and boost endurance. “Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently. And when your heart and lungs work more efficiently, you have more…

Areolar is a fibrous connective tissue, loosely packed, to hold tissue layers together. It is located in the skin, which binds the outer layers of skin to the muscles located beneath. It can be found in or near the mucous membranes, blood vessels, organs, and nerves (SIU Med, 2016). Adipose is a fatty tissue is a form of loose connective tissue that stores energy, insulates and cushions the body. It can be found…

exercise is performed, the muscles within the human body constantly relax and contract, this requires energy. Energy is sourced from a chemical referred to as adenosine triphosphate (ATP) which is comprised of an adenine base, ribose and three phosphate groups bonded together (Bergman, 1999). As the bond between the second and third phosphate group is broken, the ATP molecule converts into adenosine diphosphate (ADP) and phosphate, as a result of this, the energy that muscle cells use during…

Study after study shows that any physical activity leaves behind many positive benefits but how much exercise does that imply and what kind of benefits are likely to be seen or even felt. There is no right or wrong answer although the Department of Health and Human Services recommends a minimum of 20 minutes everyday doing moderate aerobic activity such as walking or mowing the lawn combined with 10 minutes of vigorous activity related to running or sports while mixing in 2 days of weight…
