Recommended: Outline of the cell theory

The cell itself was first discovered by Robert Hook, an English scientist, in 1665. The theory itself is made up of ideas and conclusions drawn out from the various scientists including Theodore Schwann and Matthias Schleiden who proposed the theory in 1839. Rudolf Virchow also played a part in the development of the cell theory and through the years, with additions of new specifications and redefined parts of the theory, it became more modernised. The general basis of the theory is that all organisms are composed of one or more cells. In further detail, the theory proposes that 1) all living cells arise from pre-existing cells as a result of division, 2) cells are the fundamental unit of structure and function in living organism, 3) the activity …show more content…

The functions of muscle tissue include support and movement, propulsion of blood through vessels, movement of food or body secretions through tracts, and thermoregulation. There are various types of muscle tissue, including skeletal, cardiac, and smooth. Skeletal muscle tissues are voluntary muscles that are attached to skeletal elements as well as cartilage. Cardiac muscle tissues are involuntary muscles making up the myocardium of the heart. Smooth muscle tissues are involuntary muscles in walls of hollow organs, blood vessels, as well as all other body locals where muscles perform their functions. Muscle tissue supports the cell theory as it is composed of one or more cells as well as the energy flow in relation to the energy released through use of muscles during …show more content…

Firstly, the striated muscle tissue is somewhat larger than typical cells, considering cells are known as the smallest units of life. The tissue itself can stretch to a size of over 300mm as opposed to typical cell sizes. Muscles tissues also contain multiple nuclei, despite its surroundings of a single, continuous plasma membrane. It also opposes the concept of cells working as autonomous units, meaning that the tissue doesn’t grow naturally without cultivation. Located underneath the lamina, mono-nucleated cells are stimulated as the muscle tissue is damaged. The stimulation causes the cells to divide and proceed to fuse with already present muscle fibres in order to repair and regenerate the damaged fibres. Muscle fibres use hypertrophy to lay down new protein and enlarge as they are unable to divide

What three statements make up the cell theory? The three statements that make up the cell theory are all living things are made up of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells. 1c. How did the invention of the microscope help the development of the cell theory?

Neuromuscular Therapy is founded on the study of human physiology, client assessment and a detailed understanding of kinesiology and body mechanics. Its global popularity has everything to do with a practitioner's ability to assess a patient's pain pattern and effectively treat. A detailed soft tissue assessment using regionally oriented protocols and the use of hands on techniques that have been used and proven over the last 50 years. Neuromuscular therapy addresses ischemia or reduced blood flow to the skeletal muscle tissue due to taut bands of muscle cells. NMT focuses on hypersensitive points within the taught bands of skeletal muscle cells, which often gives rise to a referral sensation phenomena that may include pain.

P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue.

Major muscles, muscular system and fibre types I am the captain of a local sports team and preparing for the up and coming season. My coach and I have spoken and noticed some players have a lack of knowledge of how the muscular system works. My coach has asked me to complete a document outlining the different functions and different fibre types each human body has to broaden the knowledge of the players. Agonist: A muscle whose contraction moves a part of the body directly, for example when your arm is flexed your bicep is the agonist Antagonist:

Introduction Double Helix by James Watson discusses many things from the science world, including concepts we have learned this semester. The concepts we have learned this semester that are in the book includes the following: DNA, protein synthesis, cells, viruses, and heredity. Because of the time period this book takes place in, however, Watson does not discuss the concepts in full detail like we can today; but there are connections made between what we discussed this semester and what James Watson discussed in the book. Key Idea 1, DNA DNA is one of the concepts we have learned this semester and is discussed all throughout the book, mainly because the book is about discovering the structure of DNA.

Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached.

However later a man that went by the name of Henri Dutrochet made the connection between animal and plant cells and he showed the structural and physical similarities between the two types of cells which made it hard for the science community to refute his claims. He also was the man to come up with the idea that the cells is regenerated from another cell but his friend François Raspail stated that every cell is derived from another cell. Later on a man named Barthelemy Dumortier brought to the table the theory of binary fission or cell division. He also observed a mid line on the old and the new cell. This to Dumortier provided him with a clear explanation of both the cells.
