The placenta
How much blood is found in the placenta, relative to how much is found in the fetus?
20-50 times more blood in the placental circulation
What term is used to describe how, in the fetus, both ventricles pump to the systemic circulation ?
Circulation in parallel
What is the fetal circulation termed a ‘circulation in parallel’?
Because both ventricles eject blood to the aorta and systemic circulation
What is the term used to describe post-natal (and adult) circulation where one ventricle is pulmonary and one is systemic?
Circulation in series
What does a ‘circulation in series’ describe?
It describes how in postnatal/adult circulation has two circulations - one to the pulmonary circulation, one to the systemic circulation

Up until how many weeks is termination allowed in the UK?
24 weeks
Define abortion.
Termination of pregnancy before 24 weeks or <500g whether spontaneous or induced
Define a threatened abortion
Vaginal bleeding in early pregnancy, cervix closed

Vaginal bleeding, cervix open, pregnancy not yet expelled but certain to be so
Define incomplete abortion
Placental tissues retained after abortion
Define complete abortion
No tissues left in uterus after abortion

Situation in which the fetus had died but is not yet expelled from the uterus
Define septic abortion
Abortion complicated by infection
Define recurrent (habitual) abortion
Three or more consecutive abortions

Premature detachment or a normally positioned placenta
Define fetal acidosis
Fetal blood pH is 7.2 or less
Define adenomyosis
ectopic endometrium (endometriosis) in the muscle of the uterus (myometrium)
What are afterpains?
Uterine contractions due to the release of oxytocin from the posterior lobe of the pituitary gland especially during suckling. Function to involute the uterus. <br></br>More intense in multiparae
What is alpha-fetoprotein?
A protein found in fetal serum that transfers to amniotic fluid and maternal blood in increased amounts when there is a fetal defect such as spin bifida or Downs syndrome
What is amniotic fluid?
Fluid surrounding the fetus composed mainly of fetal urine in late pregnancy
what is an amniotic fluid embolism?
when amniotic fluid gets into the maternal venous circulation. Foetal squames, hair and vernix become impacted in the pulmonary arterioles and thromboplastic substances cause intravascular coagulation
What is an amniotomy?
• Creating a hole in the membranes (amnion and chorion) to induce or accelerate labour. (artificial rupture of membranes)
Define antepartum haemorrhage
• Bleeding from the genital tract after 24 weeks of pregnancy
Define anencephaly
• Absence of the brain. The cerebellum and basal ganglia are sometimes present
What is the APGAR score?
• A numerical scoring system usually applied at 1 and 5 minutes after birth to evaluate the condition of the baby, based on heart rate, respiration, muscle tone, reflexes and colour
What is Arias-Stella reaction?
• Histological pattern of endometrium seen with ectopic pregnancy
What is Ashermans syndrome?
• Amenorrhoea due to adhesions in the uterine cavity, following septic abortion, or over zealous currettage
What is fetal asphyxia?
• Hypoxia leading to foetal or neonatal acidosis
Define asymptomatic bacteriuria
• Bacteria in a concentration of 105 of more per ml or urine without symptoms. This is present in about 8% of pregnant women who are at increase risk of clinical urinary tract infection during pregnancy
What is azoospermia?
• The absence of spermatozoa in semen
What is Bandl’s ring
• The grove between upper and lower uterine segments. It is situated at the level of the pubic symphysis at the onset of labour
What are Bartholin’s glands?
• Paravaginal glands susceptible to cystic enlargement and abscess formation
What is a biophysical profile?
• Method of assessing fetal well-being by ultrasound inspection of fetal behaviour and amniotic fluid volume with or without cardiotocography
What is a Bishop score?
• Method of recording the examination of the cervix to determine the ease with which labour may be induced
What is a blighted ovum?
• An embryonic pregnancy (ie) one in which arrest of development occurred at such as early stage that an embryo cannot be seen on ultrasound examination of pathological inspection. The majority of pregnancies which abort during the first trimester are of this type
Define fetal bradycardia
FHR <110
What are Braxton-Hicks contractions?
• Painless contractions of uterus before labour
What is the bregma?
• The large diamond-shaped anterior fontanelle
What is bromocriptine?
• Dopamine agonist used to treat hyperprolactinaemia and occasionally to suppress lactation
What part of a babies head is the brow?
• The part of the fetal head between the root of the nose and the anterior fontanelle
What is a kaput seccundum?
Oedema from obstructed venous return in the fetal scalp caused by pressure of the head against the rim of the cervix or birth canal
What is a cephalhaematoma?
A collection of blood beneath the periosteum of a skull bone. Limited to that bone by periosteal attachments
Define cephalo-pelvic disproportion?
Pelvis of inadequate dimensions to accommodate fetal head. It leads to mechanical obstruction and failure to progress during first or second stage of labour
What is cervical intraepithelial neoplasia (CIN)?
Potentially premalignant state of cervix associated with colposcopic abnormality
Define cholasma
Brown discolouration of the face during pregnancy
What is a chocolate cyst?
Cyst of the ovary containing blood and therefore brown in colour. Often (but not exclusively) associated with endometriosis
Define choriocarcinoma
• Malignant tumour of the placenta which usually follows hydatiform mole
What is the chorion?
• The outer fetal membrane
What is chorioinc gonadotrophin?
• Hormone produced by the placenta. Used for diagnositic purposes - as a pregnancy and as biochemical tumour marker in cases of choriocarcinoma, and also for therapy - to induce ovulation, as an LH substitute
What are the chorionic villi?
• Branching tentacles of the placenta which are the sites for metabolic exchange between maternal and fetal circulations during pregnancy. Chorionic villi may be sampled during early pregnancy to provide rapid diagnosis of chromosomal and other abnormalities (CVS)
Define climacteric
• Phase of time around the end of reproductive life in the female. The opposite to puberty
What is clomiphene?
• A drug which stimulates gonadotrophin release to induce ovulation
What is colostrum?
• Thin fluid secreted by the breasts during the first days after delivery and before production of milk proper. Rich in immunoglobulins
What is colporrhaphy?
• Suturing of the vagina to repair prolapse
What is colposcopy?
• Inspection of the cervix through a magnifying lens, usually indicated by an abnormal cervical smear
What are condylomata acuminata?
• Genital warts of viral origin found on the vulva or around the anus
What is cord presentation?
• The cord is alongside or below the pressing part with the membranes intact
What is cord prolapse?
• Serious complication in which the unbilical cord is below the foetus and is extruded into the vagina. If the membranes are still intact, it is called ‘cord presentation’
What is the corpus lutuem and what does it secrete?
• Structure in the ovary which forms after ovulation. Secretes progesterone (and oestrogen)
What are cotyledons?
• The lobes of the placenta
What is couvelaire uterus?
• Bruised uterus found after sever placental abruption. Bruising occurs because of extravasation of blood into the myometrium
What is cryptomenorrhoea?
• “Hidden menstruation”. Usually happens because a membrane above the hymen obstructs outflow, causing primary amenorrhoea.
What is curettage?
• Surgical removal of the endometrium by scraping with a curette
