    Skeletal and smooth muscle cells show a number of similarities however they also display many differences. These similarities and differences can be seen through observing the structure and appearance of these cells, their control mechanisms and the ways in which they contract. When observing both cell types under a microscope several differences are obvious. Firstly, skeletal muscles are larger than smooth muscle cells (one muscle cell can be up to 100µm in length). They are also multinucleated

    “Muscles are in a most intimate and peculiar sense the organs of the will. They have built all the roads, cities and machines in the world, written all the books, spoken all the words, and, in fact done everything that man has accomplished with matter.” (Hall, 1906.) The fundamental importance of muscular tissue in human beings is irrefutable as eloquently illustrated by G. Stanley Hall above. Muscle forms the largest group of tissue in the body, comprising of approximately 36% and 10% of body weight

    Effects of Extracellular Potassium Concentration on Membrane Potentials in Crayfish Superior Flexor Muscle Cells Intracellular measurement of membrane potentials in cells of the crayfish superficial flexor muscle can reveal the effects of varying the extracellular concentrations of potassium ion on the resting potential. Our results suggest that at high extracellular potassium concentrations, the resting potential resembles that of the potassium’s equilibrium potential, and at low potassium

    Heart (Cardiac Muscle) Cells Question 1: Briefly describe, in 500 words or less, the normal structure and function of your chosen cell type. In your answer, discuss specific features in your chosen cell type, including cell organelles. Throughout the heart, Cardiac Muscle cells are connected together to form a large network from one end to the other. These cells form a shape such that each individual cell always remains in-contact with 3 others cells at all times. The cells are held together

    Anatomy of Muscle Cells There are three types of muscle tissue in the human body. These muscle tissues are skeletal muscles, smooth muscles and cardiac muscles. Each of these muscle tissues has it very own anatomical makeup, which vary from muscle to muscle. The muscle cells in a muscle are referred to as muscle fibers, these fibers are skeletal muscle fibers, smooth muscle fibers and cardiac muscle fibers. The anatomy of a skeletal muscle fiber is formed during embryonic development. Skeletal muscle

    Muscle cells in the heart The heart is made up of cardiac muscles, which means that the heart will never get tired. The heart contains myocytes cells. The function of the myocytes is to contract and pump the blood from the heart to the lungs. Located at the right atrium of the heart, there is a group of cells, which is called the Sino atrial node. The Sino atrial node produces and releases electrical impulses, which ensure that the heart contracts and pumps the blood to the whole circulatory system

    • 3 Pages

    Hypothesis During muscle contractions cytosolic calcium and adenosine monophosphate activated protein kinase (AMPK) levels increase. Exercise also increases GLUT 4 production, which allows more glucose to be metabolized in the muscle cell. The purpose of this study was to determine whether calcium and AMPK cause the increases in GLUT 4 production in the cell. The hypothesis regarding GLUT 4 being tested in this research article stems from related research, which showed that GLUT 4 and mitochondria

    Science - 25 Isaac Huth The Skeletal Muscle Stem Cell – The Muscle Repair Men T he skeletal muscle stem cell was discovered in 1961 in the muscle fibres of skeletal muscle. It was later determined that the cell that had been found was responsible for the repair of skeletal muscle cells (Brack & Brando, 2012). Skeletal muscle is a muscle which is controlled voluntarily such as biceps in the arms or quadriceps in the legs (Reece, et al., 2012). As skeletal muscle is paramount to the survival of humans

    of stem cells (SCs) into smooth muscle cells (SMCs) is not yet fully understood, although recent research in this area has made significant strides. In previous studies, human embryonic mesenchymal stem cells (hEMSCs) were shown to differentiate by induction with transforming growth factor beta (TGF-Β) through Smad and serum response factor (SRF), p38 mitogen-activated protein kinase (p38 MAPK), and PI3k Phosphoinositide 3-kinase (PI3k).3 Human amniotic stem cell derived smooth muscle cells do not
