There are billions of neurons in our brain that sends signals from the axon to the spinal cord. In the spinal cord the axon on will send signals to many neurons from other cells and then it will generate an order. The membrane potential is an electrical state of the cell membrane and it allows gradients that cause ions to move across the cell membrane. The dispersal of charge across the cell membrane is measured in (mV). The resting membrane potential is the difference between the charges…

The muscle fibers in the presence of ATP contracted 0.07cm and 3.3% change. Under the microscope, figure 1 shows the striated fiber by clearly indicating the bands and lines of the striation. In addition, solution B, with ATP plus Salt (KCl, MgCl2) contracted the muscle fiber by 0.24cm and 9.2% change. Finally, solution C, containing only salt (KCl, MgCl2) also contracted the muscle fiber by 0.13cm and 6.1% change. Figure 2 shows the effect after adding salt and shows the striations of the fiber…

The patient is a 95-year-old gentleman who presents to the ED complaining of chest pain. The first episode was at 3 PM the day prior to admission, pressure-like described as left-sided, and pressure-like it resolved without intervention and then reoccurred again at 3 AM in the morning of presentation to the hospital. His chest pain had resolved prior to arriving in the ED. His medical history is significant for atrial fibrillation, congestive heart failure, hypertension and he has age related…

mg 3 times a day, however despite of the medication she continued to have palpitations, pressure on her chest she was unable to tolerate the pressure and palpitations therefore she presented to the ED. In the emergency room EKG was remarkable. Troponins were unremarkable. However she continued to have pressure. She had no cough or wheezing. A chest x-ray was ordered which revealed a right lung mass in the right upper lobe. CT was performed which revealed a right lung mass. It had…

To begin, the role of the ACH receptor is vital to biology. An incoming action potential to an alpha motor neuron causes acetylcholine or ACH, at the end plate. The ACH binds to ACH receptors on the sarcolemma causing a depolarization through sodium influx. In your body, calcium performs a number of basic functions. The body uses around 99 percent of its calcium to keep bones and teeth strong, as a result, supports skeletal structure and function. The rest of the calcium in your body plays…

There are many different parts of skeletal muscles that are important to the function of the muscles. Each muscle is made up of a lot of muscle fibers. Each muscle fiber has a thin coating covering the fiber called the sarcolemma. The muscle fibers also have a cytoplasmic type substance called sarcoplasm. Sarcoplasm contains large amount of glycosomes and myoglobin. Myoglobin is a protein that stores oxygen inside the muscle fibers. The muscle fibers contain striations that are made up of…

Muscle fibres. There are three types of muscle fibres; type 1, type 2a and type 2b. A. Type 1: These fibres are slow twitch or slow oxidative fibres and are red due to the presence of large volumes of myoglobin. They contract slowly but can contract repeatedly over long periods. These fibres would be suitable for an athlete such as a marathon runner because this is an endurance sporting event that requires you to use aerobic energy which relies on oxygen from the blood for the supply of energy.…

Acute coronary syndromes is an umbrella term that includes several cardiac ischemic events.1 The broad term of ACS entails ST segment elevation-ACS (STE-ACS) and non-ST segment elevation ACS (NSTE-ACS) based on the initial electrocardio- gram(ECG) finding.4 ACS usually occurs as a sudden reduction in blood flow to the coronary arteries due to rupture of the atherosclerotic plaque, which subsequently leads to myocardial ischemia or/and infarction.1, 2, 3 The American Heart Association (AHA)…

114, and respiration rate was also elevated at 37 per min. Moreover, the 12-lead ECG was performed and revealed a significant ST segment elevation that is characteristic for MI. Also, the laboratory results of increased cardiac enzymes (myoglobin, troponin, and creatine kinase) confirm the occurrence of acute MI (Ye, 2013). In myocardial infarction, a myocardial necrosis occurs and specific cardiac enzymes are released into circulation. In Mrs. S case the elevated cardiac as…

Brazilian Jiu-jitsu Brazilian Jiu-jitsu, or BJJ, is a style of martial arts, modified from the ancient Japanese art of Jiu-jitsu by the Gracie family and others, based on using an opponent’s momentum and leverage against them for defense. It involves take-downs and grappling, and has become a large sport that can be seen incorporated in the televised sport Mixed Martial Arts, or MMA. BJJ is a high intensity sport that involves endurance training as well as resistance training and explosive…
