Involuntary movement‚ found only in heart. Muscle Contraction Skeletal Muscle Muscle fibers Myofibrils Filaments Two types of filaments: - Thick: contain protein called myosin - Thin: contain protein called actin The alternation of myosin and actin form structures called striations. The energy for muscle contraction is supplied by ATP. Controlling Muscle Contraction Our muscle contractions are controlled by our nervous system. The nerve impulses in our brain signal and regulate

Chapter 9 & 10 Short Answer and Critical Thinking CHAPTER 9 Short answer 15. Name and describe the four functional abilities of muscle that are the basis for muscle response. Contractibility- is the ability to shorten forcibly when adequately stimulated. This ability sets muscle apart from other tissue types. Extensibility- is the ability to extend or stretch. Muscle cells shorten when contracting‚ but they can stretch even beyond their resting length‚ when relaxed. Elasticity-

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

As only six studies have been reported from India‚ the larger population of the country remains uncovered. According to what has been reported till date‚ b3a2 fusion transcript is most prevalent among adults and b2a2 is found to be more prevalent among children. Thus aim of this study was to find‚ that in what proportion BCR-ABL fusion transcript are present in population studied and how it is affecting prognosis of CML patients. For this study 46 patient samples were collected‚ out of which result

Chapter 7 * Why do we want to make Eukaryotic cell proteins? * Because when eukaryotic proteins are expressed in prokaryotic cells problems like been unstable‚ no biological activity and prokaryotic contaminants ( pyrogens) can occur. * Also to make the protein as natural as possible * The same expression vectors as we need for pro * We don’t need shangdolron coz that only for pro Transformation: in Eukaryotic cells: in humans means that difference in growth characters

HISTOLOGY: EPITHELIAL TISSUE o Human body composed of 4 basic types of tissue: epithelial‚ connective‚ nervous and muscular o Formed by cells and molecules of the extracellular matrix o Connective tissue: characterized by the abundance of extracellular fluid o Organs can be divided by parenchyma (composed of cells for main function of organ) and stroma ( supporting tissue) o Except in brain and spinal cord stroma made of connective tissue o Epithelial tissue: covering‚ lining protecting surfaces
