The atomic number tells the number of protons in an atom’s nucleus buy 80mg super cialis with visa, which is equal to the number of electrons in the Page 2-3 electron shells discount super cialis 80 mg. Isotope: atoms of an element the have the same number of protons, but different numbers of neutrons 1. Anion: an atom that has gained one or more electrons from another - atom and has become negatively charged. Ionic bond: bond formed by the attraction between an atom with a positive electrical charge (cation) and an atom of a negative electrical charge (anion). Hydrogen bond: bond formed when a covalently bonded hydrogen acquires a slight positive charge and becomes attracted to negatively charged atoms nearby. Synthesis reactions = Anabolism: combining 2 or more atoms or molecules to form a more complex molecule. Hydrogen bonding occurs in water due to the polar covalent bonds formed between the 2 hydrogen atoms and the oxygen atom in a water molecule. Buffers: chemical substances that regulate the changes in pH and therefore in the body help maintain homeostasis. Examples: Sucrose (table sugar) is glucose + fructose Maltose (malt sugar) is 2 glucose molecules Lactose (milk sugar) is glucose + galactose C. Carbohydrates are catabolized from polysaccharides -->disaccharides--> monosaccharides with the use of enzymes at each step. Triglycerides are the most abundant form of lipids, both in the Page 2-12 diet and stored in the body. Composed of: (1) Glycerol, a 3 carbon molecule (2) 3 fatty acids (a) Saturated fatty acids: i) have no carbon to carbon double bonds ii) solid at room temperature iii) found in animal fat iv) Examples: lard, butter (b) Unsaturated fatty acids: i) have one or more carbon to carbon double bond ii) liquid at room temperature iii) Examples: vegetable oil, corn oil 2. Examples: cholesterol, bile salts, testosterone, estrogen, progesterone and corticosteroid hormones 4. Proteins: composed of carbon, hydrogen, oxygen and always nitrogen, any may contain sulfur, phosphorous and iron. A dehydration reacion occurs, bonding the Carboxyl carbon of one amino acid to the nitrogen of the next amino acid.

The structures of the nervous system must be described in detail to understand how many of these functions are possible generic super cialis 80mg otc. There is a physiological concept known as localization of function that states that certain structures are specifically responsible for prescribed functions order super cialis 80mg free shipping. It is an underlying concept in all of anatomy and physiology, but the nervous system illustrates the concept very well. However, as specific regions and structures have been described, they were related to specific functions. Understanding these structures and the functions they perform requires a detailed description of the anatomy of the nervous system, delving deep into what the central and peripheral structures are. The place to start this study of the nervous system is the beginning of the individual human life, within the womb. The embryonic development of the nervous system allows for a simple framework on which progressively more complicated structures can be built. Starting from an embryologic perspective allows you to understand more easily how the parts relate to each other. The embryonic nervous system begins as a very simple structure—essentially just a straight line, which then gets increasingly complex. Looking at the development of the nervous system with a couple of early snapshots makes it easier to understand the whole complex system. Many structures that appear to be adjacent in the adult brain are not connected, and the connections that exist may seem arbitrary. By following the developmental pattern, it is possible to learn what the major regions of the nervous system are. The fertilized egg cell, or zygote, starts dividing to generate the cells that make up an entire organism. Sixteen days after fertilization, the developing embryo’s cells belong to one of three germ layers that give rise to the different tissues in the body. The endoderm, or inner tissue, is responsible for generating the lining tissues of various spaces within the body, such as the mucosae of the digestive and respiratory systems. Finally the ectoderm, or outer tissue, develops into the integumentary system (the skin) and the nervous system.

Platelets These are small buy discount super cialis 80mg line, non nucleated best 80mg super cialis, round/oval cells/cell fragments that stain pale blue and contain many pink granules. They 8 Hematology are produced in the bone marrow by fragmentation of cells called megakaryocytes which are large and multinucleated cells. When blood vessels are injured, platelets rapidly adhere to the damaged vessel and with one another to form a platelet plug. During this process, the soluble blood coagulation factors are activated to produce a mesh of insoluble fibrin around the clumped platelets. This assists and strengthens the platelet plug and produces a blood clot which prevents further blood loss. It also carries nutrients from the gastrointestinal tract to the cells, heat and waste products away from cells and hormones form endocrine glands to other body cells. It also adjusts body temperature through the heat-absorbing and coolant properties of its water content and its variable rate of flow through the skin, where excess heat can be lost to the environment. Blood osmotic pressure also influences the water content of cells, principally through dissolved ions and proteins. In postnatal life in humans, erythrocytes, granulocytes, monocytes, and platelets are normally produced only in the bone marrow. Lymphocytes are produced in the secondary lymphoid organs, as well as in the bone marrow and thymus gland. Although many questions 10 Hematology remain unanswered, a hypothetical scheme of hemopoiesis based on a monophyletic theory is accepted by many hematologists. According to this theory, the main blood cell groups including the red blood cells, white blood cells and platelets are derived from a pluripotent stem cell. The pluripotent stem cells may mature along morphologically and functionally diverse lines depending on the conditioning stimuli and mediators (colony-stimulating factors, erythropoietin, interleukin, etc. During fetal life, hemopoiesis is first established in the yolk sac mesenchyme and later transfers to the liver and spleen.

Los padecimientos de los linfáticos que incluimos en nuestra especialidad no son causas de muerte generic super cialis 80 mg otc, pero sí muy frecuentes motivos o indicadores de enfermedad discount super cialis 80mg amex. Prácticamente cada persona tiene al menos un episodio de linfangitis en una de sus extremidades en el transcurso de su vida. Entre 3 y 5% de la población adulta, incluso algunos niños, tienen algún grado de linfedema de sus extremidades, por diferentes causas congénitas, tumorales primitivas de ganglios o metastásicas, entre otras, que les producen una mayor o menor discapacidad. De las enfermedades vasculares periféricas no escapan niños, adolescentes, adultos, ni ancianos, como tampoco mujeres u hombres, razón por las que resulta imprescindible conocerlas para un diagnóstico precoz y una labor preventiva, la que deberán ustedes desarrollar, una vez graduados, en la comunidad, en las diferentes Áreas de Salud. Es primordial conocer sus “factores de riesgo” para lograr disminuir la discapacidad y mortalidad temprana que ellas significan. No se alivia en ninguna posición y a duras penas se mejora fugazmente con los analgésicos más fuertes incluyendo los opiáceos. Al cabo de unas 6 – 8 horas aparecen áreas de cianosis, dado el estancamiento de la sangre. Su aparición es un grave signo pronóstico: la extremidad está perdida y presumiblemente la vida del enfermo. El símil que más se asemeja es tocar el cristal de la parte inferior del refrigerador. No hay pulsos por debajo del sitio de oclusión y en el mismo sitio, es saltón, de lucha. Trombosis: Antecedentes de claudicación intermitente que pasa al dolor de reposo en pocos minutos u horas, casi siempre por inestabilidad del ateroma. Traumatismos: Heridas arteriales, aunque en estas predomina el peligroso cuadro clínico de la hemorragia y el choque. Hematoma disecante de la aorta: Grave cuadro clínico que semeja simultáneamente un infarto cardíaco y una isquemia aguda de una o más localizaciones.
