The source of energy in muscles is called adenosine triphosphate. The fibers making up the muscles link with adenosine triphosphate to obtain the energy required to allow the muscles to contract and relax (Dickinson, 2000). The fibers after obtaining the energy and receiving the necessary signal, they perform the required action. In the limbs, the signals are to allow movement or stop movement depends on the concentration of the intercellular calcium ions. Around the limbs, the muscles contain a very elastic protein known as titin (Ting, 2012,).…
To fully understand this Grip Strength exercise there most be an understanding of the foundational physiological mechanisms, which are involved. These mechanisms are all incorporated into the muscular system of the body and its foundational unit known as muscle. A muscle can be defined as a bundle of fibrous tissue connected to two or more bones by tendons giving it the ability to contract and therefore inducing movement to a specific part of the body. The muscles within the human body are differentiated into three classes known as skeletal, smooth, and finally cardiac. Smooth muscle is an involuntary muscle (under control of the autonomic nervous system) that is mainly found within the walls and organs that participate in digestion such as the stomach, intestines and esophagus, but can also be found within blood vessels as well (Argosy Publishing, 2016).…
However, there are a great deal of muscles and nerves in the forearm. When a nerve impulse transmission to synaptosomes induced depolarization, allows calcium ions to enter the cell membrane, the synaptic vesicles move forward and release acetylcholine (ACH). ACH combined with membrane receptors on the endplate cause electronic potentials, potassium and sodium ions exchanging start to spread both sides of muscle cell membrane to form the action potentials, and long with the cell membrane so that both sides of the terminal cistern will release Ca2+, Ca2+ and troponin binding to change tropomyosin, let actin exposed binding site to the cross bridge.…
Besides the very complete curriculum Rush Medical College offers in Basic Sciences and Clinical Skills to its medical students, my main interest is its multicultural environment. Having the experience of living in places with diversity of values and perspectives, I will not only feel at home at Rush Medical College, but it will help me have a greater knowledge and understanding of society and the different cultures that make up the American population. I will be able to serve patients with different backgrounds. I admire and appreciate what the Student Support Services at Rush Medical College offers to the students, giving them all the tools required to succeed in the professional and personal level. I look forward in participating in the…
The smooth muscle tissue is found inside organs like the stomach, the blood vessels and the intestines. The smooth muscle tissue is an involuntary muscle, meaning it functions on its own without been controlled. The main function of the smooth muscle tissue is to make organs tightens to move substances in and out of the organs, and it is mainly controlled by the unconscious part of the human brain. The second type of muscle tissue is the cardiac muscle and it is found in the heart. This muscle is responsible for the flow of blood throughout the body.…
Dystrophin is a protein that is located in muscles that work with movement. The job of Dystrophin is to produce muscle proteins that protects the skeletal, cardiovascular and nervous system. Dystrophin plays an important role in protein complex that work together to strengthen muscle fiber and help prevent injuries. It also plays a role in cell signaling between proteins and chemical signals. However its main job is connecting and weighing down each structural framework between proteins and molecules outside the cell.…
This entry of calcium is due to the reception of a nervous signal. A large amount of ATP must therefore be synthesized rapidly and continuously in order to allow muscle contraction. During a physical effort, the first system implemented is the anaerobic system.…
In class, we’ve talked about the myosin when seeing the microfilament. It is the motor protein of microfilament which moves along it tracks toward the positive end. It is also the major component of skeletal muscle thick filaments and thus, is involved in muscle contraction. The disease that is going to discuss is related to muscle contraction, called Myosin Storage Myopathy (also known as hyaline body myopathy).…
Muscular dystrophies (MD) are diseases that causes muscle mass loss and weakness (this is normally in children but can happen in adults). This is caused by abnormalities in genes that interfere with proper production of protein to form healthy muscles for voluntary movement. When the brain sends signals to a muscle to contract, it goes through the spinal cord and peripheral nerves to the neuromuscular junction, releasing the chemical acetylcholine that triggers muscle contraction. From here, transportation of the chemicals produced from the reaction of acetylcholine go through muscle fiber membrane and the muscle contracts or relaxes. This membrane has a group of proteins called dytrophin-glycoprotien complex that protects the muscle fiber…
This curriculum targets adult students enrolled in a Healthcare College. The goal behind this curriculum is to stimulate the medical assistant students to formulate their own opinions after confronting the topics in class, applying ethical principles resulting in ethical behaviors with the purpose of being better informed consumers, increasing their moral judgment on their personal life and workplace. Traditionally, Law and Ethics Module have been taught as a collection of concepts the student needs to memorize in order to pass a determined test. According to Rest (1988) as cited in Boss (2011) a traditional law and ethics course restricting the study of ethics to theory without performing any attempt to help the learner to be a better person,…
Questions for Medical Nutrition Therapy: A Case Study Approach 5th ed. Case 8 – Gastroparesis 1. Identify the major physiological controls for gastric emptying. • Contraction and motility are major controls for gastric emptying involving autocrine, paracrine, and neuronal systems. •…
Muscular Dystrophy is a disease when your muscles progressively weaken and degenerate over time. This is because abnormal genes or mutations interfere with the body’s ability to form healthy muscle tissue. There are many different types of Muscular Dystrophy. The word muscular dystrophy can be broken down into “trophe” meaning nourishment and “dys” meaning abnormal or abnormal nourishment. The first people to come in contact with Muscular dystrophy, in 1836, were Conte and Gioja.…
In last summer, with mixed feelings of anxiety and anticipation, I walked into the classroom in which the very first lecture of CS61A was going to be held at UC Berkeley. However, after the lecture, as an international student, as a community college student, as an adult learner, feelings of alienation and unrest occupied my mind rather than excitement. My journey of CS61A course started with anxieties, and it seemed that there was an insurmountable barrier regarding interacting with classmates. In retrospect, my sentiment solely overreacted against the environments surrounding me due to a dilution of feeling of belonging.…
Occurring mostly in males, Duchenne Muscular Dystrophy is an X-linked disorder that includes progressive muscle weakening caused by an insufficient gene for the production of a protein in the muscles called dystrophin. (Lucas-Heron, 1995) It affects about one in 3600-6000 live male births, making it the most common form of muscular dystrophy. Symptoms are most often noticeable by the time patients reach the age of three to five. The affected males will lose their ability to walk by eight to twelve years of age, making them wheelchair dependent.…
These proteins comprise of two different types of filaments that are longitudinal to the fiber, and are organized into hexagonal designs. There are both thick and thin filaments, in which every thick filament there is 6 thin filaments.. Both filaments are connected to an alternative component known as the Z-line, which is perpendicular to the fibers long side. A side note to remember is that the myofibril that runs from one Z-line to another is called a sarcomere. Down the Z-line is a small tube called the transverse or T-tubule. A membrane system called the sarcoplasmic reticulum stores and releases calcium ions that trigger muscle contraction within the…
