Infundibulum The infundibulum forms the funnel-shaped distal portion of the fallopian tube. This specialized structure serves as a crucial interface between the ovary and fallopian tube, creating a pathway for oocyte capture and transport.
Fallopian tube The fallopian tubes are bilateral muscular conduits measuring 10-12 cm in length. These tubes contain specialized ciliated epithelium and create an optimal environment for fertilization and early embryo development.

Fundus The fundus represents the dome-shaped upper portion of the uterus above the tubal attachments. This muscular region is particularly responsive to hormonal stimulation and undergoes significant expansion during pregnancy.
Fimbriae The fimbriae are finger-like projections at the distal end of the fallopian tube. These delicate structures actively sweep over the ovarian surface to capture released oocytes during ovulation through coordinated ciliary movements.
Ovary The ovaries are paired endocrine glands that produce and release eggs and hormones. These almond-shaped organs contain thousands of follicles and produce essential reproductive hormones including estrogen, progesterone, and inhibin.
Uterus The uterus is a thick-walled, pear-shaped organ that accommodates fetal development. This remarkable organ demonstrates exceptional plasticity, capable of expanding significantly during pregnancy while maintaining structural integrity.

Endometrium The endometrium forms the inner mucosal layer of the uterus. This dynamic tissue undergoes cyclic changes in response to hormonal signals, preparing for potential implantation during each menstrual cycle.
Myometrium The myometrium is the middle muscular layer of the uterine wall. This thick layer consists of interlacing smooth muscle fibers arranged in three distinct orientations and is responsible for uterine contractions during labor.
Perimetrium The perimetrium is the outer serosal layer of the uterus. This thin layer provides a protective covering and contains blood vessels, lymphatics, and nerve fibers that supply the uterine wall.
Cervix The cervix forms the lower portion of the uterus, connecting it to the vagina. This cylindrical structure undergoes significant changes throughout the reproductive cycle and serves as a gateway between the vaginal canal and uterine cavity.
Vagina The vagina is a fibromuscular canal extending from the vulva to the cervix. This elastic organ maintains a complex microbiological environment and undergoes significant changes in response to hormonal fluctuations.
Comprehensive Guide to Female Reproductive Anatomy
Anatomical Organization
The female reproductive system demonstrates precise layered architecture essential for its multiple functions. Each layer contributes uniquely to reproductive physiology and maintains specific mechanical and biological properties. The intricate relationship between these layers ensures optimal reproductive function.
Histological Layers
Endometrial Complex
The endometrium consists of two primary layers:
- Functionalis layer: Undergoes cyclic changes
- Basalis layer: Provides regenerative capacity
These layers respond differently to hormonal stimulation and play distinct roles in the menstrual cycle and implantation.
Myometrial Architecture
The myometrium contains three distinct muscle layers:
- Outer longitudinal layer
- Middle vascular layer
- Inner circular layer
This complex arrangement enables coordinated contractions essential for labor and delivery.
Clinical Significance
Reproductive Pathology
Understanding layered anatomy is crucial for:
- Identifying pathological changes
- Surgical planning
