Birth – All About I Have To Know

Birth is the act or process of bearing or bringing forth offspring, also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe. In some species the offspring is precocial and can … [Read more…]

Fifth Through Eighth Weeks of Stages Fetal Development

Fifth Through Eighth Weeks of Stages Fetal Development /Weeks five through eight of gestation are characterized by the development of the major organ systems, including the circulatory, nervous, lymphatic, and gastrointestinal systems. During this time, the embryo is extremely susceptible to the effects of teratogens. Development Cardiovascular System The first organ system to develop during … [Read more…]

Fourth Week of Development of Embryo

Fourth Week of Development of Embryo (the embryonic disc) will grow from about 2 to about 6 mm. The processes of the third week (neural tube formation, development of blood circulation) continue in the fourth week. At the same time, the amnion increases enormously in size, while the yolk sac does not. This is the … [Read more…]

What is the most common cause of acute kidney injury?

What is the most common cause of acute kidney injury?/Acute kidney injury (AKI), previously called acute renal failure (ARF) is a sudden decrease in kidney function that develops within 7 days, as shown by an increase in serum creatinine or a decrease in urine output, or both.[rx] Causes of AKI are classified as either prerenal (due to decreased blood flow to the kidney), … [Read more…]

Acute Kidney Injury – Causes, Symptoms, Treatment

Acute kidney injury (AKI), previously called acute renal failure (ARF) is a sudden decrease in kidney function that develops within 7 days, as shown by an increase in serum creatinine or a decrease in urine output, or both.[rx] Causes of AKI are classified as either prerenal (due to decreased blood flow to the kidney), intrinsic renal (due to damage to the kidney itself), … [Read more…]

Third Week of Development – Anatomy, Types, Functions

Third Week of Development/The third week is concerned with establishing left and right handedness, the craniocaudal axis, as well as the conversion of the bilaminar disc into a trilaminar embryo. Additionally, there is further specialization of the extraembryonic structures that will continue to support the embryo during the intrauterine phase. Gastrulation During gastrulation, the embryo … [Read more…]

Trophoblast Development – Anatomy, Mechanism

Trophoblast Development/Week 2 is often referred to as the week of twos. It’s the week when the embryoblast, extraembryonic mesoderm and trophoblast each separate into two distinct . Trophoblast Development Trophoblasts are the outer layer of cells that provide nutrients to the embryo and form part of the placenta. Key Points The trophoblast is subdivided into two layers, the inner cytotrophoblast, … [Read more…]

The First Week of Embryonic Development

The first week of embryonic development is filled with an eclectic arrangement of physical and biochemical changes. Each step is a part of a cascade of events that must be intricately coordinated in order to produce a healthy baby at the end of the thirty eight to forty week period. However, the events of the first … [Read more…]
