Anatomy and physiology Essay

The Haversian system houses the blood vessels in Mrs. Morgan’s compact bone. The bone tissue sticking out the skin, the bruising and the extensive bleeding from the arm are the signs and symptoms related to the disruption of these structures by her bone fractures. The bleeding and the bone tissue sticking out of the skin shows how the blood vessels within the Haversian system, such as the periosteal arteries supplying the outer area and the nutrient artery which supplies the inner part of bone have been disrupted. The disruption of these arteries within the Haversian system will then make Mrs Morgan’s humerus susceptible to avascular necrosis.

There are many specific types of fracture that occur in the thumb and first metacarpal, fractures of the proximal phalange and distal phalange are simpler to manage than the more complex Bennett and Rolando fractures which involve the joint between metacarpal and carpal bones (Day & Stern, 2010). If a fracture occurs in the first metacarpal, or proximal or distal phalange the patient will experience pain to the thumb, the area may appear bruised and will swell; patient also in most cases experience a loss in function and are unable to complete tasks such as pinching motions (The Royal Berkshire NHS Trust, 2013). Anne is not experiencing any loss of function in her arm and there is no swelling of the thumb; consequently, it is unlikely that Anne has fractured her first metacarpal, distal or radial

Use the lecture folder to help you complete this guide. The more detail you can provide the better prepared for the test you will be.

1. Name the circulatory system that carries blood from the heart to the lungs and back to the heart.

The structure that furnishes the axis for the rotation of the head from side to side is the:

The first step in the diagnosis is doing laboratory studies to detect any secondary causes. These include serum chemistry levels of calcium, phosphate, vitamin D, magnesium, PTH, and CBC (complete blood count). Detecting secondary causes is important because it will change the treatment plan. Even though there might be some small fractures can’t be seen

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate.

As Jim’s muscles are at maximum demand, his mitochondria are unable to produce the needed ATP through aerobic respiration because oxygen is unable to diffuse fast enough into his muscle fibers. At this time anaerobic

The concentration of dissolved substances is less in the extracellular fluid than in the cytoplasm. Hypotonic Solution Concentration of dissolved substances (solute) Concentration of water (solvent) What happens to an animal cells? Inside the cell Greater Less Outside the cell Less Greater Membrane

How we came to know what we know now about anatomy and physiology has always been a great curiosity of anyone interested in the medical field. Knowing the history can lead to even more discoveries in the future. When you think of anatomy you imagine something like this picture below.

The injuries he suffered were overwhelming, and so sudden that at first, he didn't know anything was wrong. Only when he tried to put weight on his leg did he realize the extent of the damage. He jokes about it today. "I found that I didn't have a leg to stand on," he chuckles. Most of the flesh on his leg was ripped away, leaving his foot attached only by the tendons in the back of his calf. Bones were exposed and the bleeding was profuse. He also suffered head and internal injuries.

Define equilibrium potential: Equilibrium channels can be calculated using the Nernst Equation and the Goldman-Hodgkin-Katz equation. Equilibrium potentials are membrane potentials when an ion does not diffuse through the membrane. It is also associated with potassium leaving the cell through leak channels.

Stress fractures account for approximately twenty percent of athletic injuries, with eighty percent of stress fractures occurring in the lower leg. Stress fractures in the lower extremity are common injuries among individuals who participate in endurance, high load-bearing activities (2). The incidence of these injuries has risen due to earlier and longer participation in sports (3). Stress fractures occur when repetitive mechanical load exceeds the biological capacity of bone, causing micro-damage (1). This rate exceeds the rate at which bone can repair itself, requiring recognition and management of risk factors (2). The initial stage of bone failure is typically called a stress reaction. If the repetitive loading continues, the stress reaction can form into a true stress fracture (3).

The anatomy and physiology of the human body is extremely complex in many different aspects. Scientifically, the human body is organized from simple to complex. The organization sequence begins with diminutive cells and finishes with multiplex organ systems. All people are typically organized in the same fashion. However, psychologically all people do not process information the same way. People have a myriad of motives for the actions they take in life. For instance, a person may be motivated or inspired by a situation he or she has been in, and they decide to act upon his or her beliefs. John Grisham, a well-known novelist, was inspired to become a writer by past circumstances he has experienced, the knowledge he obtained by being a lawyer, through the stimulating people he has met throughout his life thus far, and to prove that people can experience a little adventure while reading.
