Cardiac surgery

muscles, smooth, skeletal, and cardiac. The smooth muscles are usually found within the walls of internal organs like the blood vessels and the stomach. Smooth muscles are also involuntary. It is like this in the humans as well as the dogs. The skeletal muscles are connected to the skeletal system. These muscles are controlled voluntarily by a dog when the dog runs, eats, walk, or plays. Just like smooth muscle this is in the humans for the same reason. The cardiac muscle is in the heart and…

different muscle tissues, skeletal, cardiac, and smooth. Skeletal muscle tissue cells are long, striated, and have many nuclei. Cardiac muscle tissue, just like the skeletal is also in striations. These cells are short and branched. Unlike, the skeletal muscle tissue these cells die single nucleated. They are connected by intercalated discs. Smooth muscle tissue is not striated. Its Cells are short and spindle shaped. The cardiac muscle is also nucleated. In a Cardiac Muscle is a…

Professor Bearing’s Journey Through Cancer In the story “Wit “by Margaret Edson, the author depicts how a professor by the name Vivian Bearing was brilliant, cold hearted and then she became filled with kindness. Professor Bearing was a tough love teacher; she doesn’t really care about the students and their struggles. Her main fervor is for 17th Century poetry, especially the complicated Holy Sonnets of John Donne; well at least at the beginning of the play. In the latter half of the story…

The ability for muscles to contract and shorten to produce movement lies within its structure at a cellular level. The muscle organ is surrounded by a fibrous connective tissue called the epimysium, continuous to the perimysium, which separates the organ into small bundles called fascicles. Each fascicle can be further separated into muscle fibers by the endomysium. The plasma membrane of an individual muscle fiber is called the sarcolemma, which plays a major role in generating an action along…

voluntarily. There are three layers of connective tissue in the skeletal muscle known as epimysium which surrounds the entire muscle, perimysium which surrounds muscle fibers known as fascicles, and endomysium which contains capillaries and nerve fibers. Cardiac muscle is found in the heart, also striated but is involuntary meaning it beats on its own without stimulation. They are also more dependent on aerobic metabolism for the energy they use to continue contracting. Smooth muscle known as…

One of the main goals in the field of exercise science is to determine methods of enhancing performance during exercise or competition. When comparing methods of performance enhancement two essential theories come to mind: utilization of the stretch-shortening cycle (SSC) and post activation potentiation (PAP), which both result from pre-activation (Fukutani, Misaki & Isaka, 2016, Nibali, Chapman, Robergs & Drinkwater, 2013) The SSC focuses on increases in muscle force output through a…

Explanation of EMG signals EMG stands for electromyography. Muscle fibres generate tiny electrical currents prior to the production of muscle force. These currents are generated by the exchange of ions across muscle fibres membranes, a part of the signalling process for the muscle fibres to contract. EMG is the signal made, it can be measured by applying conductive elements or electrodes to the skin surface, or invasively with the muscle. When using EMG, tiny devices named electrodes are used…

Section A “Selective Connexin43 Inhibition Prevents Isoproterenol-Induced Arrhythmias and Lethality in Muscular Dystrophy Mice” is a research paper that was conducted by Dr. Fraidenraich and his colleagues. Duchenne muscular dystrophy (DMD) is a severe form of muscular dystrophy that is life threatening and associated with muscle degeneration. It affects many newborn males, meaning that it is caused by an X-linked mutation. This mutation leads to the absence of a very important protein called,…

Discussion Vascular access, along with airway management is a standard of emergency care, and is an essential part of cardiopulmonary resuscitation in many groups of patients. Peripheral vascular access is the most efficient means of gaining vascular access as it’s induces minimal trauma, is the safest method of gaining access to venous circulation. It may however be difficult in stressful situations and require several attempts despite its widespread usage failure may result in prehospital…
