Although the cervix is part of the uterus, structure and function differ from the main body of the uterus.
SITUATION
  • It forms the lower 1/3 of the uterus and is the area below the isthmus  which includes the internal and external os.
  • It enters the vagina at right angle.
SHAPE 
  • The cervical canal is fusiform and the cervix as a whole is Barrel shaped.
SIZE
  • It is 2.5cm long in adult. It becomes bigger in pregnancy and at times at birth it becomes almost equal size with the uterus.
GROSS STRUCTURE
  • Supravaginal cervix – this is the portion that lies outside and above the vagina.
  • Superiorly, it meets the border of the uterus at the isthmus.
  • The infravaginal cervix – the portion which projects into the vagina.
