Unit 2 AoS 1 (Chapter 6 & 7) Flashcards
Amniotic Fluid
The fluid surrounding the embryo/foetus that protects the unborn baby
Antipartum
Relating to the period directly before birth
Blastocyst
A cluster of cells in which some cell differentiation occurred
Cell differentiation
When cells take on specialised roles
Congenital abnormality
Sometimes called congenital anomaly, a condition characterised by malformed body parts (either external such as limbs or internal such as organs) that is present at birth
Endometrium
The nutrient-rich lining on the uterine wall in which the ovum (blastocyst) embeds or that is expelled every month if pregnancy does not occur
Haemorrhage
Excessive bleeding
Implantation
Occurs when. A cluster of cells that will become an embryo attached itself to the endometrium
Intracytoplasmic sperm injection
A process whereby a single sperm is injected directly into an ovum.
Jaundice
A condition that can affect newborn babies. Symptoms may include a yellow tinge to the skin and the whites of eyes, drowsiness, feeding difficulties and dark urine.
Mandatory fortification
A law that requires certain nutrients to be added to specific foods during production
Morula
A solid ball of cells created from a zygote
Placenta
An organ that allows the transfer of nutrients, gases and wastes between mother and foetus
Regenerate
Regrow to replace damaged, old or dead cells or tissue
Teratogens
Anything in the environment of the embryo that can cause defects in development. (Tobacco smoke, alcohol, shellfish, prescription medication, and some diseases like measles)
Ultrasound
A tool that uses high-frequency sound waves to create a visual representation of something that can usually not be seen. Ultrasound is used to monitor foetal development.
Zygote
A full cell resulting from the fusion of a sperm and an ovum
Antenatal
Occurring before birth
Carrier
A person who has inherited a genetic trait or condition but does not display the trait or symptoms. They are able to pass the gene on to their children, who may or may not display the trait or symptoms.
Chromosomes
Strands of DNA that contain genetic information
Developmental milestones
Physical, social, emotional and intellectual developments that most children achieve by specific ages.
Endocrine system
The system in the body that regulates the production and release of hormones (through the glands)
Foetal Alcohol Spectrum Disorder (FASD)
Describes a range of features seen in babies who have been exposed to alcohol during the prenatal stage
Genes
The blueprint of the body that controls growth, development, and how the body functions
Haemophilia
An inherited condition characterised by an inability of the blood to clot. Both males and females carry the gene for haemophilia, but the condition is usually present only in males
Hormones
A chemical in the body that causes a change in the functioning of a specific tissue or organ
Inherited condition
A condition that is passed down from parents to children
Listeria Monocytogenes
Bacteria that can increase the risk of still birth, miscarriage and premature labour in women
Maternal nutrition
The dietary intake of the mother during pregnancy
Sex-linked chromosomes
Genetic material that determines the sex of the developing baby
Vaccinations
The administration of a microorganism of a disease to bring about an immune response
