What is the base deficit?
Reverse of base excess
Ph= ?
Negative log [H+]
What does the uterus consist of?
The fundus, body and cervix. It communicates laterally with the uterine tubes and posteriorly with the vagina
What term is used to describe the position of the uterus?
Ante-flexed meaning bent forwards
What spaces are created by the cervix lying into the vagina?
The vaginal fornices
What muscle stabilises the cervix?
The Levator ani muscle
What do the uterine tubes do?
Conduct the ova from the ovary to the uterine cavity
Where are the uterine tubes found?
Upper boarder of the broad ligament (connects uterus to pelvis)
What are fimbrae?
Finger like ciliated projections on the infundibulum
How does the uterus relate to the bladder and rectum?
Posteriosuperior to the bladder and anterior to the rectum
What do the ovaries suspend from?
The posterior leaf of the broad ligament via the mesovarium (double fold of peritoneum )
Where do the ovaries frequently lie?
The ovarian fossa
What supplies the ovaries ?
The ovarian arteries that are branches of the abdominal aorta
What is the mons pubis?
Rounded hair bearing part of the vulva in front of the Pubic symphysis
What is the clitoris comprised of and where is it derived from?
3 bundles of erectile tissue and derives from the genital tubercle
Where does the ductus deferens terminate?
When it anastomoses with the duct from the seminal vesicle to form the ejaculatory duct
What’s the function of the seminal vesicle?
To produce an alkaline fluid that makes up a majority of semen. The fluid contains proteolytic enzymes that break down the clotting factors in semen. This ensures it stays fluid
How does an ultrasound work?
Sound waves transmitted via a probe that can be transmitted through fluid and soft tissue but are reflected on hard tissues e.g. bone. These reflections are recorded and create an image. Painless and safe as uses sound waves not radiation (like X rays)
What does sonohystography do?
Improve the quality of the ultrasound
Give two examples where transvaginal imaging would need to be used
If the patient is obese or the fetus is postioned abnormally in the uterus
When is X-ray used in imaging pregnancy?
Diagnose infertility.
When is the fetal heart beat recognisable ?
7 week scan
What is the outcome of the 12 week scan ?
Approximate date of delivery by measuring the crown-rump length
What does the 20 week scan identify?
Any abnormalities, which at this stage wouldn’t be isolated to one system
Define multipotent, totipotent and pluripotent?
Multipotent- ability to differentiate into multiple types of cells e.g. bone marrow. Pluripotent - differentiate into most cells apart from those involved in the formation of the placenta and totipotent (everything)
What are the 3 things a stem cell can do?
Self renewal- apoptosis
Progenitor- proliferation
Differentiation
