Placenta
The document summarizes the structure and physiology of the mammalian placenta. It discusses that in viviparous animals, the embryo develops inside the mother's uterus due to insufficient yolk. The embryo attaches to the uterine wall via the placenta to obtain nutrients from the mother's circulation. The placenta allows the exchange of food, oxygen, and waste between the fetus and mother. It then describes different placental structures and classifications in mammals.
Bcq preparation class
The document contains questions and answers related to anatomy and physiology. It discusses topics like muscle actions, bone structure, cartilage, fetal development, and more. The incorrect statements in the questions generally relate to minor details like examples or terminology.
Multiple pregnancy in obstetrics and gynaecology
This document provides information about multiple pregnancies involving twins or more. It defines multiple pregnancy as when more than one fetus develops simultaneously in the uterus. There are two main types of twins - monozygotic (identical) twins which develop from one zygote splitting, and dizygotic (fraternal) twins which develop from two separate zygotes. The document discusses the increasing incidence of multiples due to assisted reproduction techniques and lists various terminology used to describe twin and higher-order pregnancies.
Identical Twins
Identical twins come from a single fertilized egg that splits into two embryos. They share the same womb, placenta, and amniotic fluid. The splitting can occur very early in development, leading identical twins to be genetically identical. Complications can arise during pregnancy from shared anatomy, like entanglement of the umbilical cord or an imbalance in nutrients received from the placenta. After birth, identical twins generally have very similar appearances and DNA, though they develop distinct personalities.
Identical Twins
Identical twins come from a single fertilized egg that splits into two embryos. They share the same womb, placenta, and amniotic fluid. The splitting can occur between 4-12 days after fertilization, leading to different outcomes in terms of chorionicity and amnionicity. Complications in pregnancy can arise due to shared anatomy, like entanglement of the umbilical cord or twin-to-twin transfusion syndrome. Identical twins have identical DNA and may look like mirror images of each other, though they have distinct personalities.
Womb Twin Survivors (1) - Signs of a twin
Part 1 of the introduction to the Womb Twin Survivors Research Project. Explaining what a womb twin survivor is. Womb twin survivors are the sole survivors of a twin or multiple pregnancy. Their twin died in the womb or around birth and this includes the "vanishing twin" pregnancies. Various signs are explained, first during the pregnancy, then at the birth and finally inside the body of the survivor, which includes a dermoid cyst and a teratoma.
Multiple pregnancy
This document discusses multiple pregnancy, also known as twin or higher order pregnancies. It defines multiple pregnancy as the presence of more than one fetus in the abdomen of a pregnant woman. Multiple pregnancies can be categorized based on the number of fetuses as twins, triplets, quadruplets, etc. The document outlines risk factors, classifications, complications, diagnosis, and management of multiple pregnancies. It describes how multiple pregnancies can occur and the different types, and emphasizes the importance of preventing preterm birth in managing these high-risk pregnancies.
USMLE GENERAL EMBRYOLOGY 017 Twins monozygotic monozygotic monozygotic.pdf

Belly Button CSGNA 2016
The document discusses the visual examination of the belly and navel from anatomical, historical, social, and medical perspectives. Anatomically, the navel is located at the midpoint of the body and develops from the umbilical cord that nourishes the fetus. Historically, many religions and cultures have ascribed spiritual or theological significance to the navel. Medically, examination of the navel can provide clues to intra-abdominal diseases and conditions. Variations in navel appearance like outies can occur normally or indicate issues like hernias.
Breech presentation
This document discusses breech presentation, which occurs when the fetus is in a longitudinal lie with the buttocks or feet presenting at the pelvic brim instead of the head. The incidence is about 3-4% and spontaneous correction usually occurs by 34 weeks. Breech presentations are classified as complete or incomplete. Etiologies include prematurity, factors preventing version, fetal abnormalities, and multiparity. Diagnosis involves clinical examination and sonography to determine type and position of breech.
placentation in animals ppt_014943.pptx
The document discusses different types of placentation in animals. It begins by describing the basic functions of the placenta in connecting the developing fetus to the uterine wall and facilitating nutrient/gas exchange. There are three main types discussed: 1) choriovitelline placenta, which is a temporary early structure in most mammals formed from yolk sac tissues; 2) chorioallantoic placenta, the definitive placenta of higher mammals formed by attachment of the allantois to the chorion; 3) placentas are further classified as deciduous, non-deciduous, or contra-deciduous based on whether maternal tissues are shed or not during birth. Specific animal examples are
Reproduction in humans revision igcse_fernando
The document discusses various topics related to human reproduction including:
1) It defines key terms like embryo, sperm, fetus, ovum, and zygote and explains which are alive and can grow into a new individual.
2) It compares male and female gametes in terms of their size, structure, and relative numbers.
3) It defines ovulation as the release of an ovum from the ovaries, which occurs about every 28 days in humans.
4) It explains why the chance of fertilization is restricted to only a few days each month in humans.
Placentation in mammal,classification of placenta and function
The placenta is an organ that develops during pregnancy in mammals to connect the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. It is a discoid, circular organ around 15-20 cm in diameter and 2.5 cm thick that weighs approximately 500g at term. The placenta has both fetal and maternal surfaces, with the fetal surface covered by the amnion and bearing the umbilical cord, and the maternal surface being rough and spongy where it attaches to the uterine wall. The placenta serves critical functions like nutrient, gas and waste exchange between mother and fetus, acting as an endocrine organ and barrier between

Canine vaginal_cytology_final.pptx
Based on the cytology provided, the bitch was likely bred during estrus and therefore has a high chance of pregnancy since she was bred at a very fertile time in her cycle. The smears from Tuesday-Thursday show 100% cornified cells indicating estrus, and she was bred only 2 days prior to the first smear, well within the fertile window.
Umblical cord presentation
The document discusses the anatomy and abnormalities of the umbilical cord that can be identified on prenatal ultrasound. It provides details on the normal structure of the cord including the umbilical vessels and Wharton's jelly. Common abnormalities discussed include short or long cord length, umbilical cord cysts, single umbilical artery, velamentous or furcate cord insertion, and umbilical cord coiling abnormalities. Associations of various cord abnormalities with adverse pregnancy outcomes are also summarized.
TWINS - Elango Navin Raj Group 1432.pptx
This document discusses different types of twins, including:
- Identical (monozygotic) twins, which develop from one fertilized egg that splits into two embryos. They are always the same gender and share DNA.
- Fraternal (dizygotic) twins, which develop from two separate eggs fertilized by two separate sperm, similar to normal siblings. They may be different genders.
- Rare types like mirror twins, whose features appear symmetrically opposite, and conjoined twins, who are physically joined.
The document also explains that twins may share a placenta, amniotic sac, or chorion, or have their own, and outlines the differences between diamniotic-d
Multiple pregnancy
This document discusses multiple pregnancies, specifically twins. It begins by defining multiple pregnancy as more than one fetus developing simultaneously in the uterus. Twins are the most common type of multiple pregnancy. Twin pregnancies can be either monozygotic (identical) or dizygotic (fraternal). Monozygotic twins result from a single fertilized egg splitting, while dizygotic twins develop from two separate eggs fertilized in the same cycle. Multiple pregnancies are higher risk and require additional care and monitoring due to increased risks of complications such as preterm birth. The zygosity and chorionicity of twins provides important information about membrane status and genetic similarity.
handouts1. embryology implantation, hormones
During weeks 1-4 of human embryology:
- Fertilization occurs and the zygote undergoes cell division as it travels down the fallopian tube.
- Implantation in the uterine wall occurs around 1 week after fertilization.
- Gastrulation transforms the bilaminar embryo into the three germ layers (ectoderm, mesoderm, endoderm) by around 3 weeks.
the first amniotes
This document summarizes key aspects of animal diversity by discussing amniotes. It describes amniotes as the first tetrapods to fully adapt to land using amniotic eggs equipped with membranes that protect embryos. The earliest amniotes resembled small lizards and evolved 312 million years ago. They diverged into synapsids and sauropsids, including modern reptiles, birds, and mammals. Amniotic eggs evolved adaptations like the amnion, yolk sac, chorion, and allantois membranes to protect embryos in harsh land conditions. The document also provides a cladogram illustrating the phylogeny of amniotes.

How is a chorioallantoic placenta different from a choriovitelline placenta? Give an example of
an animal or group of animals that depend on each.
Solution
1) The family Peramelidae/bandicoots has a chorioallantoic placenta. The rest of the marsupials
have a choriovitelline placenta.
2) The choriovitelline placenta is less vascularized than the chorioallanoic placenta. The portion
in contact with the uterine lining is convoluted to increase the surface area in contact with the
uterus but it is not deeply imbedded in the uterine lining. A small amount of uterine milk diffuses
from the uterine tissue to the fetus, but most of the nourishment for the fetus comes from the
yolk sac.
3) The chorioallantoic placenta is more highly vascularized. The fetal and maternal tissues are
more highly interconnected due to the many finger-like projections known as villi that grow into
the uterine lining. Gases and nutrients diffuse from the maternal capillary beds, across the
placental membranes and into the fetal capillaries, and vice versa..
Placentation in mammals
This document discusses placental classification in mammals. It describes how placentas are classified based on the fetal membranes involved (yolk sac or chorioallantoic), nature of contact with the uterus (indeciduate or deciduate), villi distribution (diffuse, cotyledonary, etc.), and histological intimacy with maternal tissues (epitheliochorial, syndesmochorial, etc.). The formation and development of the placenta from implantation through birth is explained. Various placental structures and types found in different mammalian orders are outlined.
Ems birth slideshow FINISHED COPY
This document provides information about childbirth and gynecological emergencies for first responders. It defines key terms related to female anatomy and the birthing process. It also explains the three stages of labor: early/active labor where contractions become stronger and more frequent; transition where contractions are strongest and birth is imminent; and delivery where the baby is born. It aims to educate first responders about normal labor and signs of potential emergencies.
H uman reproduction
The document discusses morula in humans. It states that a morula:
- Has almost equal quantity of cytoplasm as an uncleaved zygote but much more DNA.
- Is an early stage embryo consisting of cells in a solid ball within the zona pellucida, produced through rapid division of the zygote.
- Undergoes divisions rapidly because there is no growth, so cell number increases while size decreases, resulting in almost equal cytoplasm but more DNA compared to an uncleaved zygote.
Human reproduction
The document discusses morula formation in humans. It states that a morula:
- Has almost equal quantity of cytoplasm as an uncleaved zygote but much more DNA.
- Is an early stage embryo consisting of blastomers in a solid ball within the zona pellucida, formed through rapid division of the zygote.
- Does not change in overall size as the cell divisions are rapid and alternate between DNA replication and mitosis, so cell number increases while cell size decreases.
Conjoined Twins
Conjoined twins are identical twins who are physically joined together in some part of the body. They occur due to incomplete separation of the embryo early in pregnancy. Conjoined twins can be separated surgically if their vital organs are not shared, but the separation process is complex and risky. There are different classifications of conjoined twins depending on the part of the body where they are joined.
Conjoined Twins
Twins occur when more than one egg is fertilized or a single egg is fertilized multiple times, leading to multiple fetuses. Conjoined twins are identical twins who are joined in some part of the body due to incomplete separation after fertilization. They share the same zygote and sometimes internal organs. Conjoined twins are very rare, occurring in about 1 in 100,000 births. They often do not survive due to the complexity of sharing organs and bodies.

all the information provided to the student
Key concepts - When ATP is hydrolyzed to ADP + P i , energy that is usable for a cell is
released - Through coupling reactions, ATP drives endergonic reactions using energy derived
from exergonic reactions. - Catalysts speed up the rate of a reaction but do not allow the
occurrence of a reaction that would not otherwise take place. - An enzyme may undergo a
change in shape called induced fit as the result of binding its substrate. - Environmental factors
such as pH and temperature affect enzyme activity. Introduction Many people enjoy watching
and catching fireflies on warm summer nights, but the attraction isn't mutual; a firefly's primary
goal with its impressive light show is to find a mate. Male and female fireflies use specific
patterns of light flashes to attract one another. The flashes are emitted from the firefly lantern, an
organ located in the firefly abdomen. Light is a form of energy, which means that fireflies must
divert some of their energy to produce these light flashes. Researchers used a biochemical
approach to learn how this is done. When the lanterns of fireflies are ground up and extracted
with water, the extract briefly produces an intense light, which then fades away. If ATP is added
to the extract, light is again emitted, and again, it fades. The graph below shows the duration of
light emission as a function of the amount of ATP added. When anaerobic conditions were used,
no light was observed. Through additional investigations, the researchers discovered that light
was produced because of a chemical reaction involving a compound called luciferin. The
researchers again examined the lantern cell extracts and purified Luciferase, the enzyme that
catalyzes the reaction by which luciferin emits light. The researchers also observed how, when
mixed with a fixed amount of Luciferase, varying the abundance of luciferin, ATP, and
magnesium ( Mg 2 + ) resulted in different amounts of light (light intensity). The table below
shows light intensity as each variable changed. 1. Based on these data, what molecules are
necessary to produce light by firefly lanterns? What role does each molecule serve? 2. Explain
how energy taken in by the firefly from its environment is made available for the production of
light in a firefly lantern. 3. Additional research has shown that an activated intermediate forms at
the active site of the enzyme as luciferin reacts. This intermediate consists of luciferin covalently
bonded to adenosine monophosphate (AMP). Still at the active site, this intermediate then reacts
with oxygen to make an oxidized form of luciferin with the emission of light. The diagram below
shows these steps. Redraw the diagram, adding steps to illustrate how coupling reactions could
be involved to provide the energy needed for light emission. 4. What evidence is there that the
enzyme is sensitive to environmental factors? Suggest possible reasons why this enzyme
responds as it does to .

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
