1b. Tryavarta Yoni and anatomical insights of Garbhashaya with marma, peshi
b) Tryāvarta Yoni and Anatomical Insights of Garbhāśaya with Marma & Peśī
Learning Objective
By the end of this chapter you should be able to (i) explain the classical concept of Tryāvarta Yoni (three intravaginal spirals/folds), (ii) describe the situation, shape and relations of the Garbhāśaya (uterus) as per Ayurvedic classics, and (iii) correlate the relevant marma (vital spots) and peśī (muscle) descriptions around the female pelvis with modern anatomy.
1) Classical overview: Yoni and Garbhāśaya
Yoni in Āyurveda denotes the female genital passage in the broader sense of the term (the “parturient path/apatyapatha”), serving as the route for coitus, menstruation, conception and parturition. Ācārya Suśruta provides a precise morphologic description of this passage and the uterine bed:
- Shankha-nābhi-ākṛti yoni — the vaginal canal resembles the navel of a conch, signifying a spiralled lumen.
- Tryāvarta yoni — there are three avarta (spirals/involutions) in the canal; the Garbhāśaya is situated in the third, posterior spiral.
- Rohiṭa-matsya-mukha ākṛti — the uterus is likened to the mouth of the Rohiṭa fish: narrow at the mouth (cervical os) and expanding superiorly (uterine cavity/fundus).
Context note for exams: These three statements together form the classical Tryāvarta Yoni–Garbhāśaya core and are frequently asked in viva/short notes. Remember the trio: Śaṅkha-nābhi (shape) → Try-āvarta (folds) → Garbhāśaya in 3rd avarta (location).
2) Tryāvarta Yoni — structure & clinical mapping
2.1 The three avarta (spirals/folds)
While the classical text employs the imagery of spiralled turns, teachers and examiners commonly correlate them to recognizable subdivisions:
| Classical term | Practical/clinical correlate | Key points |
|---|---|---|
| 1st Avarta | Apatyapatha (vagina) | Fibromuscular tube leading from vestibule to cervix; distensible during coitus and labour. |
| 2nd Avarta | Garbhashaya-grīvā (cervix) | Narrowed region; “mukha” of Garbhāśaya; provides mucus barrier and dilates in labour. |
| 3rd Avarta | Garbhāśaya (uterus) | Site of implantation and fetal development; classical seat in the third posterior avarta. |
Exam tip: Write: “Yoni — śaṅkhanābhyākṛti, tryāvartā; tasyāstu tṛtīyāvarte Garbhāśaya,” with reference to Suśruta Śārīrasthāna 5, ‘rememberable verses’ describing these features. In structured answers, add a neat labelled sketch of the three avarta and uterine bed.
2.2 Orientation & relations of Garbhāśaya
Suśruta places the uterine bed behind the basti (urinary bladder) and between Pittaśaya and Pakvāśaya (interpreted broadly as viscera flanking the uterine bed). This nicely matches the pelvic anteverted–anteflexed orientation described in modern anatomy.
Shape: Rohiṭa-matsya-mukha ākṛti communicates a funnel-like organ—narrow cervix opening into a broader cavity, consistent with the uterine isthmus and fundus configuration.
3) Garbhāśaya: structure–function notes for answers
- Definition (functional): Garbha-āśaya — the cavity that receives, retains and nourishes the embryo, and from which the fetus is ultimately delivered.
- Mukhadvaya (two cervical lips): The concept of narrow mouth implies a controlled entrance/exit (coitus, menses, labour).
- Paridhi (bounds): Anterior — Basti; superior/lateral — adnexal regions (where Ayurvedic authors allude to structures like plāla-m-antargata comparable to ovaries/beeja-granthi in interpretive literature); posterior — rectal segment.
Short-note cue: “Garbhashaya—sthāna, ākṛti, sambandha (relations) and karma (functions),” quoting Tryāvarta Yoni and Rohiṭa-mukha ākṛti earns full credit.
4) Peśī (muscles) around the female parturient passage (Suśruta)
Suśruta gives a systematic count of peśī (muscles) and explicitly states additional muscles in the female related to stana (breasts) and the parturient passage:
- General peśī distribution: 500 muscles in the body, with region-wise counts.
- Female-specific addition:
- 10 peśī around the two stana (five each), which attain full growth at puberty.
- 4 peśī around the yoni-mārga (two at the external and two at the internal orifices).
- 3 peśī around the “os” (cervical mouth).
- 3 peśī along the passages of ovum and sperm (beeja-mārga).
These descriptions parallel the levator ani, perineal musculature, cervical support, and adnexal/parametrial structures in modern terms.
4.1 Clinically useful mapping
| Suśruta’s mention | Probable modern correlate | Clinical relevance |
|---|---|---|
| “External yoni peśī (2)” | Bulbospongiosus, superficial perineal muscles | Coital function; support of vestibule; perineal tears in labour. |
| “Internal yoni peśī (2)” | Pelvic floor (levator ani) components at vaginal wall | Pelvic support, continence, descent/cystocele/rectocele implications. |
| “Around os (3)” | Cervical stromal musculature/fibromuscular ring | Cervical competence, incompetence → habitual abortion, labour dilation. |
| “Passages of ovum/sperm (3)” | Tubal/parametrial smooth muscle tracts | Tubal peristalsis, ectopic risk, infertility. |
| “Stana peśī (10)” | Pectoral fascia, suspensory structures | Lactation mechanics, puerperal changes. |
Exam tactic: After listing Suśruta’s figures, write a crisp correlation to pelvic floor supports (utero-sacral, cardinal/ Mackenrodt’s, round ligament) under snāyu/bandha headings to display integration.
5) Marma around the female pelvis: what to know for OSCE/short notes
Although specific “Yoni-marma” is not enumerated, several marmas lie immediately adjacent to or influencing the apatyapatha–garbhāśaya region. From Suśruta Śārīrasthāna (Marma-vibhāga), remember these names and implications in obstetric/gynecologic contexts:
- Basti-marma (suprapubic/vesical region): injury can be rapidly fatal or lead to severe vātaprakopa, urinary fistulae and sepsis; practical caution for lower midline incisions, suprapubic catheterization.
- Guda-marma (anal region): injury risks hemorrhage, continence loss, pelvic sepsis; relevant to obstetric perineal tears and posterior vaginal surgeries.
- Nabhi-marma (umbilical): central vital spot; in obstetrics, relevant to operative entry and postpartum care.
- Vankṣaṇa-marma (inguinal): proximity to round-ligament/inguinal canal, femoral vessels; consider during hernia/inguinal surgeries and lymphadenopathy.
- Kukundara-marma (buttock) & Katikāṭarūṇa-marma (sacro-iliac ridge area): deep gluteal/sacro-iliac region; relevant to pudendal block, sciatic safety, and pelvic pain syndromes.
Answer framing: State that pelvic obstetric procedures must respect marma-kṣetra to avoid prāṇa–vāta derangement, hemorrhage, infertility and sphincter injuries. Cite Marma-vibhāga (Suśruta Śārīrasthāna 6) in references.
6) Integrating classical and modern anatomy (for long answers)
6.1 Location & relations (diagram strongly advised)
- Anterior: Basti (urinary bladder) — hence a retrovesical uterine bed in classical phrasing.
- Posterior: Rectal segment — correlates with recto-uterine pouch (Douglas) clinically.
- Superior/lateral: Beeja-granthi region (adnexa) — inferred from classical passages discussing beeja mārga/ovum passage.
6.2 Functional correlates
- Ritukāla: yoni passage “open and receptive” — conducive to bīja-praveśa (sperm entry).
- Garbha-dharana: third avarta uterine bed — site for implantation and garbha-poshana (nourishment).
- Prasava: cervical os and yoni peśī dilate/relax, pelvic floor yields, conforming to “Rohiṭa-mukha” funnel guiding the fetal head.
7) How to write Tryāvarta Yoni–Garbhāśaya in 8–10 marks
- Intro (2–3 lines): Define Yoni as apatyapatha and its śaṅkhanābhyākṛti.
- Tryāvarta (2–3 lines): State three avarta; Garbhāśaya in the 3rd posterior avarta.
- Garbhāśaya ākṛti (1–2 lines): Rohiṭa-matsya-mukha description.
- Relations (3–4 lines): Basti (front), rectum (behind), adnexal/tubal corridors; clinical orientation A-V-A-F.
- Peśī points (3–4 lines): Female-specific extra 20 peśī; list 4 around yoni, 3 at os, 3 along beeja-mārga, 10 in stana.
- Marma caution (2–3 lines): Name Basti, Guda, Nabhi, Vankṣaṇa; mention surgical/obstetric caution.
- Diagram: Labelled sketch showing three avarta and uterus.
8) Shloka supporting anatomical study
Suśruta emphasizes direct observation (śarīra-avicchinna adhyayana) for correct anatomical understanding:
शरीरे चैव शास्त्रे च दृष्टार्थः स्याद् विशारदः।
दृष्टश्रुताभ्यां सन्देहमवापोह्याचरेत् क्रियाः॥
(Suśruta Saṃhitā, Śārīrasthāna 5/51)
Meaning: One becomes adept when the truths of the body and the śāstra are both directly seen; removing doubts by what is seen and what is heard, one should then act (perform procedures). This underlines how Suśruta derived Tryāvarta-yoni and uterine details from systematic cadaveric study before applying to practice.
Why quoted here? Examiners appreciate when you anchor pelvic anatomy answers in Suśruta’s anatomical method along with the Tryāvarta description.
9) Viva-oriented pearls
- Mnemonic for the triad: “Conch–Three–Fish-Mouth” → Śaṅkha-nābhi (shape), Try-āvarta (folds), Rohiṭa-mukha (uterus).
- One-liner: “Garbhāśaya lies in the 3rd posterior avarta of yoni (Suśruta).”
- Female extra peśī: “10 (stana) + 4 (yonimārga) + 3 (os) + 3 (beeja-mārga).”
- Marma caution keywords: Basti, Guda, Nabhi, Vankṣaṇa—avoid traumatic insult; control doṣa-udreka and rakta-srāva.
