What is the all-or-nothing principle, and how does it work? In order to fully understand the all-or-nothing principle, one must first know what an action potential is and its relevance to the all-or-nothing principle. Therefore, an action potential is a very short wave of positive electrical charge that travels down an axon. In connection to the all-or-nothing principle, it is important to know that the action potential obeys the all-or-nothing principle. The all-or-nothing principle states that…

neurodevelopmental evaluation due to his involvement in study protocol, 16-H-0144, Impact of Elastin Mediated Vascular Stiffness on End Organs. XX is from Manchester, England. He was diagnosed with supraventricular aortic stenosis (SVAS) and experienced multiple cardiac arrests and heart surgery associated with this diagnosis. He currently experiences hypertension, difficulty regulating his temperature, difficulties with memory, migraine headaches, GI pain, and anxiety. XX is color blind. XX’s…

metabolism. The tests that were run by the researchers showed that the stem cells that were encapsulated in the gel lasted longer while multiplying in number. These cells repair the tissue much more efficiently and marked higher growth production of cardiac…

Muscle contraction is a process leading to the shortening and or development of tension in muscle tissue. Tension is developed in muscle tissue when muscles contract. That tension may or may not lead to movement. To contract means to shorten; however, this is not always the case in a muscle contraction. The tension may cause muscle to remain the same, elongate, or condense. When muscles decrease in length (e.x. lifting weights) it is called a concentric contraction. When muscles increase in…

Bradyarrhythmias - occurs when the heart rate is slower than normal (lower than 60 bpm) . if the heartrate is too slow not enough blood reaches the brain (this can cause you to pass out). Bradyarrhythmias is due to the flawed cardiac conduction system (group of cardiac muscle cells in the walls of the heart that send signals to the heart causing it to contract) at the level of the atrium or atrioventricular. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is…

The heart is one of the major organs in the body that is essential. The heart is considered a pump that helps the blood flow, continuously, throughout the body. The heart is located under the rib cage, between the lungs, and more on the left side of the breastbone. It has two major coronary arteries, electrical impulses, four chambers, and four valves to help the blood flow one way. Deoxygenated blood enters the right atrium from the superior and inferior vena cava. When the right atrium…

Blood Pressure: Systolic and Diastolic Abstract Blood pressure is when your heart beats and so it pumps blood back up to your body for it to have energy and oxygen. However, as your blood pushes it creates strength, so this creates blood pressure. Pulse is to see the rate of your heart going beats per minute. In this experiment, we gather data to see if the level of physical activity could affect the result of the systolic and diastolic measures in blood pressure and if the pulse would also be…

Supraventricular Tachycardia, Adult Supraventricular tachycardia (SVT) is a kind of abnormal heartbeat. It makes the heart beat very fast and then beat at a normal speed. A normal heart beats 60 to 100 times a minute. This condition can make your heart beat more than 150 times a minute. Episodes of a fast heartbeat can be scary but they are usually not dangerous. They can lead to problems if: They happen often. They last a long time. Symptoms of this condition include: A…

how to administer the possibly life saving measure. All high schools should require a cpr course to be taking in order to graduate because Cpr saves lives, most cardiac arrest situations occur at home, and so they should be able to tell the difference between cardiac arrest and a heart attack. About 900 americans die everyday due to cardiac arrest According to the new york times. when you know how to perform Cpr you might be saving a relative's life, loved ones, or even a stranger. One of the…

Muscle cells play a very important role in movement of our body. There are three types of muscle cells in vertebrates: skeletal, cardiac and smooth. We are mainly going to be concerned with skeletal muscle for this particular experiment. The skeletal muscle is responsible for the voluntary movement of whole body or body parts, manipulation of external objects, support for our skeleton (Sherwood, 2010, p257). Skeletal muscles have a striated structures of alternating light and dark bands…
