All cells must contract in a specific sequence. This sequence is determined by the pathway known as the conduction system. 2. Cardiac cells are connective and autorhythmic. What does this mean? Connective cells, action potentials, (excitatory signals) can propagate from

Pig Trachealis Smooth Muscle Pharmomechanical coupling uses Internal Calcium stores whilst Electromechanical coupling uses Extracellular Calcium Crystal Nguyen School of Anatomy, Physiology and Human Biology, The University of Western Australia, WA, 6009 Introduction Smooth muscle contraction occurs when calcium is present in the smooth muscle cell and binds onto calmodulin to activate myosin light chain kinase (Wilson et al., 2002). Phosphorylation of myosin light chains result in myosin

There are the Smooth, the Skeletal, and the Cardiac muscular tissues. Smooth muscles are made of spindle-shaped cells. Smooth muscles are found in the skin, internal organs, reproductive system, major blood vessels, and excretory system. Skeletal muscles are composed of long fibers surrounded by

CARDIOVASCULAR SURGEON Career Overview – • A cardiovascular surgeon, otherwise known as a cardiothoracic surgeon or a car-diac surgeon, is a physician who specializes in the treatment of disease and injury of the heart, as well as the major blood vessels located in the chest. A cardiovasc-ular surgeon’s job is usually more demanding than that of other surgeons. The procedures involved in operating on the heart are very complex. (Stephanie Dube Dwilson, 2011). Education and/or Training Required

most other species, tunas have a fundamentally different swimming mode, a radically different thermal biology, increased rate functions (e.g. standard metabolic rate (SMR), aerobic capacity, heart rate and gut clearance) and a markedly different cardiac physiology. Thermoregulation is essential for maintaining high speed. These qualities are necessary for migration, feeding and foraging. In addition to thermoregulation, its unique composition of white and red muscle allows it to be so fast. The

SIMILARITIES AND DIFFERENCES BETWEEN SELETAL, CARDIAC, AND SMOOTH MUSCLE: Skeletal Muscle Structure: skeletal muscles cells are like long fiber structures, That contain many nuclei and are subdivided into smaller structures that are called “myofibrils”. The “Myofibrils” are created of two kinds of “myofilaments”. Thin filaments are made of two strands of the protein-actin and one strand of a regulatory protein coiled with each other. Thick filaments are staggered arrays of “myosin molecules”. *

Introduction The purpose of this lab was to measure resting heart rate and blood pressure as well as during submaximal exercise to see the effects of exercise has on the body. Submaximal graded exercise test is any physical activity whose intensity increases at regular intervals up to but never exceeding 85 percent of an individual’s maximum heart rate. Testing the submaximal level is ideal because all subjects can participate and it is safer. Heart rate is the number of beats per minute measured

Case study: Clark Kent Age: 17 Height: 5’11” Weight: 165 pounds Gender: Male Resting Heart Rate: 75 bpm Clark is a junior in high school and is eager to gain some muscle mass and strength before his final football season next year. He knows very little about nutrition and his diet consists primarily of processed foods (i.e., fast food, cafeteria food, etc.). He eats two or three meals per day on average. Clark 's training regimen has been sporadic and inconsistent recently so he is coming to you

is keeping blood flowing through 60,000 miles of blood vessels that feed organs and tissues. The cardiac muscle is the tissues that make up your heart. The heart sends blood around your body. When there is a problem with your heart and it can’t pump blood it is critical for it to be fixed. This is when the cardiovascular surgeon steps in. Cardiothoracic surgeon, also known as heart surgeon or cardiac surgeon or cardiovascular surgeon, is a healthcare professional who specializes in the diagnosis
