ANATOMY AND PHYSIOLOGY OF FALLOPIAN TUBE AND PELVIC FLOOR
FALLOPIAN TUBES
Propels the ovum towards the uterus
is to transport sperm towards the egg, which is released by the ovary, and then allows passage for the fertilized egg back to the uterus for implantation.
DETAIL OF STRUCTURE
The distal ends of the fallopian tubes consist of fingerlike projections called
fimbriae
that massage the ovaries at ovulation to help extract the mature ovum.
the fallopian tube is about 12cm long and about 1,2cm in diameter
The Fallopian tubes are composed of
simple columnar epithelium
with hair-like extensions called cilia which carry the fertilized egg
The fallopian tube consist of three coats which is the
serous, muscular, and mucous.

PELVIC FLOOR
FUNCTION
pelvic organ support, bladder and bowel control and sexual function.
The ability to contract the pelvic floor correctly can be difficult. A proper pelvic floor contraction incorporates both a squeeze and a lift without contraction of other muscles such as the adductors and gluts.
The pelvic cavity contains the bladder, rectum, pelvic genital organs and terminal part of the urethra.
ROLES OF A PELVIC FLOOR MUSCLES ARE
It support the abdominopelvic visceral ( bladder, intestines, uterus etc.
resistance to increases in intra-pelvic/abdominal pressure during activities such as coughing or lifting heavy objects.
urinary and faecal incontinence, the muscle fibres has a sphincter action on the rectum and urethra, they relax to allow urination and defecation.
3 Main parts of the pelvic floor
Fascia coverings of the muscles
.
Coccygeus muscle.
The coccygeus (or ischiococcygeus) is the smaller, and most posterior pelvic floor component – as the levator ani muscles are situated anteriorly.
It originates from the ischial spines and travels to the lateral aspect of the sacrum and coccyx, along the sacrospinous ligament.
Levator ani muscle ( largest component)
The levator ani is a broad sheet of muscle. It is composed of three separate paired muscles; pubococcygeus, puborectalis and iliococcygeus
2 HOLE IN THE PELVIC FLOOR THAT HAS SIGNIFICANCE
UROGENITAL HIATUS –
an anteriorly situated gap, which allows passage of the urethra (and the vagina in females
RECTAL HIATUS–
a centrally positioned gap, which allows passage of the anal canal.
