Cerivx Flashcards
functions of the cervix
It facilitates the passage of sperm into the uterine cavity. This is achieved via dilation of the external and internal os.
Maintains sterility of the upper female reproductive tract. The cervix, and all structures superior to it, are sterile. This ultimately protects the uterine cavity and the upper genital tract by preventing bacterial invasion. This environment is maintained by the frequent shedding of the endometrium, thick cervical mucus and a narrow external os.
anatomic; structure o the cervix
The cervix is composed of two regions; the ectocervix and the endocervical canal.
The ectocervix is the portion of the cervix that projects into the vagina. It is lined by stratified squamous non-keratinized epithelium. The opening in the ectocervix, the external os, marks the transition from the ectocervix to the endocervical canal.
The endocervical canal (or endocervix) is the more proximal, and ‘inner’ part of the cervix. It is lined by a mucus-secreting simple columnar epithelium. The endocervical canal ends, and the uterine cavity begins, at a narrowing called the internal os.
what is the serive
Fig 1.0 - Overview of the female reproductive tract. F
The cervix is the lower portion of the uterus, an organ of the female reproductive tract. It connects the vagina with the main body of the uterus, acting as a gateway between them.
how is the cervix different t the uterus
Anatomically and histologically, the cervix is distinct from the uterus, and hence we consider it as a separate anatomical structure.
