What are the types of pelvic regions?

The false pelvis lies above the pelvic brim and has no role in childbirth. The true pelvis, below the brim, is important for childbirth.

What is the pelvic inlet or brim?

It's the area where the true pelvis begins, marking the boundary between the false and true pelvis. It is formed by the upper border of the symphysis pubis anteriorly, the sacral promontory posteriorly, the sacroiliac joints, iliopectineal lines, and pubic crests.

What are the key elements of the pelvic cavity?

The Pelvic Cavity is a segment shaped like a cylinder, with a roof formed by the pelvic brim and a floor formed by the plane of least pelvic dimension. The anterior wall is the symphysis pubis and the posterior wall is the sacrum.

What is the pelvic outlet?

The pelvic outlet is the bottom opening of the true pelvis. It is bounded anteriorly by the lower border of the symphysis pubis, posteriorly by the coccyx, and laterally by the ischial spines.

How does the antero-posterior diameter of the pelvic outlet change during labor?

The antero-posterior diameter (from the tip of the sacrum to the lower border of the symphysis pubis) is 11 cm in early labor but can increase to 13 cm during the second stage of labor due to coccyx movement.

What is the bi-spinous diameter and why is it important?

The bi-spinous diameter, a crucial measurement for the pelvic outlet, is the distance between the tips of the ischial spines. A diameter less than 9.5 cm can create difficulties during labor.

Study Notes

Reproductive System Anatomy & Physiology

  • Female Reproductive System (FRS) Learning Objectives: Students will be able to describe the parts (external, internal organs, and breasts) of the FRS, and explain their functions.

  • External Organs (Vulva): Include Mons Veneris (Mons Pubis), Labia Majora, Labia Minora, Clitoris, Vestibule (Urethral Orifice, Skene's Glands, Vaginal Orifice, Bartholin's Glands), and Perineum.

  • Internal Organs: Comprise Vagina, Uterus, Fallopian Tubes, and Ovaries.

  • Breast Anatomy: Contain mammary glands, connective tissue, 15-25 lobes connected by ducts opening into the nipples. Nipples are erectile tissue, areola is pigmented. Breast size is influenced by heredity, fat, and glandular tissue.

Male Reproductive System

  • Male Reproductive System Functions: Produce, maintain, and transport sperm (reproductive cells); discharge sperm during sex; produce and secrete male sex hormones.

  • Male Reproductive System External Organs: Include penis, scrotum, and testicles (testes).

  • Penis Anatomy: Composed of three parts: root (attaches to abdominal wall), body or shaft, and glans (tip). The glans contains the urethral opening, and is covered by foreskin (sometimes removed through circumcision).

  • Scrotum Anatomy: The loose pouch-like skin that contains the testes and various nerves and blood vessels. Temperature regulation of testes is a key function.

  • Testicles (Testes) Anatomy: Oval organs that produce sperm and testosterone.

  • Accessory Organs: Epididymis (transports and stores sperm), Vas Deferens (transports mature sperm), Ejaculatory Ducts (fusion of vas deferens and seminal vesicles), Urethra (carries urine and semen), Seminal Vesicles (produce a sugar-rich fluid), Prostate Gland (provides fluid to ejaculate), and Bulbourethral Glands (lubricate urethra).

Pelvic Anatomy

  • Pelvic Anatomy, General Objective: Acquired complete knowledge of the normal female pelvis.

  • Specific Objectives: List features of the normal female pelvis, identify types of pelvises, discuss components and measurements of the gynecoid pelvis, and identify the pelvic diaphragm.

  • Bony Pelvis Composition: Composed of two innominate bones each consisting of ilium, ischium, pubis, one sacrum, and one coccyx.

  • Pelvic Division: Two sections, false pelvis (above pelvic brim) and true pelvis (below pelvic brim). The true pelvis is for childbirth.

  • Pelvic Diameters: Antero-posterior, diagonal conjugate, transverse, and oblique diameters need careful measurement during childbirth.

  • Pelvic Outlet: Obstetric outlet is essential for child birth. Bounded anteriorly by the lower border of the symphysis pubis, posteriorly by the coccyx, and laterally by ischial spines.

  • Pelvic Types: Gynecoid (most favorable for childbirth), Anthropoid, Android, and Platypelloid are the four types, each with different pelvic dimensions.

  • Pelvic Floor: Soft tissue filling the pelvic bony outlet; contains pelvic peritoneum, pelvic fascia, levator ani muscles, perineal muscles, and the skin of the perineum.

  • Pelvic Outlet Importance for Childbirth: Pelvic outlet parameters help determine childbirth difficulty.
