Extraordinary Measures is a 2010 drama film that tells the story of John Crowley, a successful businessman who is forced to confront the challenges of finding a cure for his two children who are suffering from a rare genetic disorder called Pompe disease. The film raises several important questions about the nature of illness, the role of science and technology in finding cures, and the power of hope and determination in the face of seemingly insurmountable challenges.
One of the main questions that the film raises is the extent to which science and technology can help us to overcome serious health issues. The film shows us the lengths that John Crowley is willing to go to in order to find a cure for his children, including working with a controversial scientist named Dr. Robert Stonehill who is not well-respected by the scientific community. The film suggests that there is always hope for finding a cure, no matter how difficult the challenge may seem, and that we should not give up on the search for answers.
Another question that the film raises is the role of hope and determination in the face of serious illness. Despite the bleak prognosis for his children, John Crowley remains determined to find a way to save them, and he never gives up hope that a cure will be found. The film suggests that hope and determination are powerful forces that can help us to overcome even the most difficult challenges, and that we should never give up on our dreams and goals, no matter how difficult they may seem.
Overall, Extraordinary Measures is a powerful and inspiring film that raises important questions about the nature of illness, the role of science and technology in finding cures, and the power of hope and determination in the face of seemingly insurmountable challenges. It is a film that reminds us that we should never give up on our dreams and goals, no matter how difficult they may seem, and that we should always strive to find ways to overcome even the most difficult challenges that life throws our way.
4 Types of Tissues in Human Body and its Functions
All substances that enter the body must cross an epithelium. Our tissues can be categorized into four major types: Epithelial, Connective, Muscle, and Nervous. Connective tissue supports other tissues and binds them together bone, blood, and lymph tissues. The weakest cell have 2. The basal layer is usually anchored to a layer of underlying connective tissue.
Muscular tissue such as cardiac, smooth, and skeletal muscle. There are three general classifications whose names a derived by their appearance: sqaumous, cubodial, and columnar. Three serous membranes are found lining the thoracic cavity; two membranes that cover the lungs pleura and one membrane that covers the heart pericardium. What are the functions of body tissue? For example, it envelops and protects organs, stores nutrients, forms tendons and ligaments, and appears in many organs to increase their mechanical resistance, for example in the deep layers of the skin. It is made up of cells called chondrocytes which are embedded in a matrix of collagen and elastic fibers. Their lateral side surfaces are specialized to do specific jobs based on the type of epithelial cell. Their basal lower-most surface is the basement membrane.
Some muscle movement is voluntary, which means it is under conscious control. Some epithelia often include structural features that allow the selective transport of molecules and ions across their cell membranes. Connective tissue is classified into three main categories: proper connective tissue further divided into dense and loose connective tissue , embryonic further divided into mesenchyme and mucous , and specialized connective tissues cartilage, adipose, bone, and blood. Describe this transition, discussing the steps and processes that lead to these specialized cells. Epithelial tissue lines the GI tract organs and other hollow organs and is found on the skin surface epidermis. The neuron is the cell responsible for the electrical transmission and form the nervous tissue next to the glial and microglial cells.
The four types of tissues in the body are epithelial, connective, muscle, and nervous. If muscle tissue is attach to two different bones, when that muscle shortens, one of the bones will be pulled. The apical upper-most surface can have one of many features including lumen, microvilli, and cilia. Connective tissue is a type of body tissue that binds organs and body parts together. Our organs are made up of many tissues sheets of cells connected together to serve different purposes, to execute actions inside our body and help us get on with our day-to-day lives. Understanding how tissues work is fundamental to understanding how organs work. The skin is an example of a cutaneous membrane.
Each type of tissue differ from each other in structure which in turn determines its function. They are involved in functions like secretion, absorption, and excretion, etc. Examples of different types of connective tissue Muscle tissue Muscle tissue is characterized by its contractile capacity. As these cells become specialized, they lose their ability to differentiate into all tissues. They help in the contraction and relaxation of man organs like lungs, stomach, uterus, etc.
Muscle cells are excitable, meaning they generate a current when stimulated. A mucous membrane, sometimes called a mucosa, lines a body cavity or hollow passageway that is open to the external environment. EPITHELIUM Functions jobs : 1 It protects us from the outside world — skin. . Schwann cells do the same thing as the oligodendrocytes, only in the peripheral nervous system. Further, the upper layer cells might be keratinized, and dehydrated to protect from heat, microbes, wear and tear, chemicals, etc.
What are the four main types of tissues in the human body and what are their key characteristics?
They are formed during birth and last till death. This is further differentiated as a Fibrous tissue b Elastic tissue Fibrous tissue It has collagen fibers and fewer fibroblasts. Gilia are cells specialized cells too. The first embryonic cells generated have the ability to differentiate into any type of cell in the body and, as such, are called omnipotent, meaning each has the capacity to divide, differentiate, and develop into a new organism. The zygote divides into many cells.
There are several types of gilia cells, each with their own function. Connecting tissues to one another e. These surfaces can be found in cavities in contact with the exterior and in internal cavities and conduits. What are the 4 types of tissues in the body? Unlike other cells, these cells do not multiply. . This cartilage is of three types as a Hyaline cartilage b Elastic cartilage c fibrocartilage Bone tissue This is formed by osteocytes bone cells along with wth collagen fibers and inorganic salts like phosphate and calcium.
List the four (4) basic tissue types and give their main functions.
. For example connective tissues separate muscles, arteries, veins, and nerves from one another. Nervous tissue is found in the brain, spinal cord, and nerves. Two main classes of cells make up nervous tissue: the neuron and neuroglia. Two basic types of tissue membranes are recognized based on the primary tissue type composing each: connective tissue membranes and epithelial membranes Figure 4. Reference: Principles of Anatomy and Physiology. Neurons are specialized cells that transmit electrical signals between the brain and the rest of the body.
What happens when a terminally differentiated cell reverts to a less differentiated state? Such changes can be detected through histology , the microscopic study of tissue appearance, organization, and function. The zygote, or fertilized egg, is a single cell formed by the fusion of an egg and sperm cell. There is one more type of epithelium, i. What is the largest tissue in the body? Ultimately, some of these ectodermal cells become further restricted and differentiate in to nerve cells. This forms a great way of communication between different organs in the body to maintain homeostasis.
