...GENERAL EMBRYOLOGY - PERIODS IN DEVELOPING FETUS Embryology studies will develop human from fertilization until birth (gestation-38th weeks, or 40 wks). Periods of fruit development are: preembrionski (lasting from fertilization until the end of the second week), Embryonic (lasts from the third to the end of 8 weeks) and fetal (runs from 9 to 38 weeks). The fruit in the embryonic period is called an embryo, fetus and fetal. The origins of all organs are formed in the embryonic period. In the fetal period comes to strong growth of the fetus, especially in the region of the head, as well as to morphological and functional differentiation of all organs are formed in the embryonic period. Further differentiation processes continue even after birth (postnatal period of development). Part of the embryo and fetus on whose head is referred to as cranial (head), the last part of the caudal (tail), the ventral side of the ventral and dorsal side of the dorsal. MAIN CHARACTERISTICS OF DEVELOPMENT The main characteristics of development includes processes that occur in the process of creating every tissue and organ in the human body. This includes the following processes: 1. The proliferation - increasing the number of cells that occurs as a result of a number of asymmetric cell division by division (when the mother of one daughter cells are formed identical to the mother cell and daughter cell that directs the differentiation); 2. Growth - weight gain and the size of the formed tissue...

...EMBRYO #WEEK 1 Day 1. Fertilization In the beginning is the egg. Inside the fallopian tube, a mature human egg waits in a state of arrested development. Just released from the ovary, it is the largest cell in the human body. The egg is packed with nutrients, growth factors, enzymes and proteins — nearly everything it needs to jump start the development of a human embryo. Except for one little thing — it needs a sperm. If a sperm doesn’t penetrate the egg’s tough outer membrane to activate it within the next 24 hours, the egg will die.¬¬ The sperm cells contain the male genetic contribution to the new genome that will be produced at the completion of fertilization. Sperm cells are produced during the process of meiosis, which occurs in the testis during spermatogenesis. At the completion of meiosis each sperm contains a haploid genome (one chromatid from each chromosome pair). During fertilization and the first stage of embryonic development, the egg runs the show. All a mature human egg really needs from a sperm is its DNA — the genetic code stored in 23 chromosomes inherited from the father. When combined with 23 chromosomes in the egg from the mother, the new embryo has the full complement of genetic material required to make a human being. The fertilization process commences with the sperm initiating the penetration of the zona pellucid. Firstly, the sperm squeezes through cells left over from the follicle. When it reaches the jelly coat, the sperm’s acrosomal enzymes digest...

...is caused by the bacteria tubercle bacillus or mycobacterium tuberculosis. The bacteria was discovered by a microbiologist Robert Koch in 1882. Transmission When a person who is infected with TB exhale, sneezes, cough, speaks or sings tiny droplets of fluid containing tubercle bacilli are released into the air. The mist, or aerosol is inhaled through the nasal passage. The bacteria can stay in the air for several hours. A fetus can be infected with tuberculosis by inhaling or swallowing the amniotic fluid of an infected mother. Once inhaled tubercle bacilli reach the alveoli and are spread by the lymph vessels to nearby lymph nodes. The bacilli moves through the blood vessels to distant organs. They may become inactive or latent or they may cause the active disease. The tissue damage is caused by the reaction of the person’s tissue to its presence. After several weeks the host develops an immune response to the bacilli, cells attack the bacilli and permit the initial damage to heal and prevent future disease permanently. Being infected with the bacteria does not mean that the person is contagious or ill. They might have symptoms of the disease. The chest x-ray will remain negative. However they can become ill after many years. Symptoms The symptoms of Tuberculosis disease are weight loss, fever, night sweats, coughing, chest pain, coughing greenish-yellowish sputum, coughing up of blood, loss...

...OSHA The Occupational Health and Safety Administration (OSHA) is a federal agency that operates under the U.S. Department of Labor. They are a law regulating agency that enforces laws that are put in place to protect employees in their place of work. The mission of OSHA is to ensure that businesses provide safe and healthy working environments for all their employees. In 1974 OSHA was developed and established by congress. In the 1960s there was a 20% rise in work-related accidents and injuries and something needed to be done to keep these numbers from increasing. House Representative William A. Steiger successfully passed a bill that would create OSHA. President Richard M. Nixon signed The Occupational Safety and Health Act of 1970 on December 29th of 1970. OSHA was open for business in April of 1971. OSHA covered 56 million workers at 3.5 million various industries and businesses. OSHA created and organized standards at foundations such as the National Fire Protection Organization, American National Standards Institution, and the American Conference of Governmental Industrial Hygienist. OSHA developed its first training program in Chicago in the mid-1970s. The training programs purpose was to educate its inspectors, and administer employers and employees training on safety standards. In 1975 OSHA had state authorities instruct onsite consolation programs at no cost. In the 1980’s OSHA started to make medical and exposure records the main focal point. In the 80’s OSHA...

...Knowledge and Conformance of Delivery Room Staff on Essential Newborn Care Protocol A Thesis Proposal Presented to the Faculty of the Graduate School of University of the Visayas Cebu City, Philippines In Partial Fulfillment of the Requirements for the Degree of Masters of Arts in Nursing Major in Maternal and Child Health Nursing by MAY PRINCES T. ABUCEJO, RN August, 2012 THE PROBLEM AND ITS SCOPE INTRODUCTION Rationale of the Study The Child Survival Strategy published by the Department of Health has emphasized the need to strengthen health services of children throughout the stages. The neonatal period has been identified as one of the most crucial phases in the survival and development of the child. The Millennium Development Goal Number four (4) of reducing under five child mortality can be achieved by the Philippines, however, if the neonatal mortality rates are not addressed from its non-moving trend of decline, MDG 4 might not be achieved (http://www.doh.gov.ph/node/2664). Based on health statistics, the Philippines is one of the 42 countries that account for 90% of under-five mortality worldwide. Eighty two thousand (82,000) Filipino children under five years old die every year. Thirty seven percent (37%) or 40,000 of them are newborn. Majority of them (3/4) die within the first two days of life, mostly from preventable causes. The high mortality and morbidity rates in newborn are directly related to inappropriate hospital and community practices...
