Explanation

The cardinal ligaments, also known as Mackenrodt's ligaments or transverse cervical ligaments, are the primary source of support for the uterus and cervix.
They are thick, fibromuscular bands of connective tissue that extend from the cervix and upper vagina to the lateral walls of the pelvis.
This lateral attachment provides the strongest suspension, preventing the uterus and cervix from descending into the vagina (prolapse).
They are considered the most crucial component of the uterine support system, along with the uterosacral ligaments.

Option A: The round ligaments are fibromuscular cords that help keep the uterus in an anteverted (tilted forward) position.
Option B: While the uterosacral ligaments provide significant support by pulling the cervix posteriorly, they are not considered the single major support structure compared to the cardinal ligaments.
Option C: The broad ligament is a double fold of peritoneum that drapes over the uterus and adnexa. It primarily serves as a mesentery, containing blood vessels, nerves, and other ligaments.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical support structures of the uterus and cervix as background academic context rather than a clinical decision trigger.
Understanding uterine supports is critical for diagnosing and managing pelvic organ prolapse (POP), a common condition where pelvic organs descend from their normal position.
During hysterectomy (surgical removal of the uterus), the surgeon must carefully identify and secure the cardinal and uterosacral ligaments to the vaginal cuff to prevent subsequent vaginal vault prolapse.
Damage to these ligaments during childbirth is a major risk factor for developing POP later in life. Nurses play a key role in identifying at-risk patients and educating them on pelvic floor exercises (Kegels) to strengthen muscular support.

How to Approach the Question

First, identify the core of the question: it asks for the 'major' or primary support structure for the uterus and cervix.
This is a factual recall question based on female pelvic anatomy.
Mentally review the functions of the different uterine ligaments.
Differentiate between ligaments that position the uterus (like the round ligament) and those that provide structural suspension against gravity.
Compare the supportive roles of the cardinal, uterosacral, and broad ligaments. Recall that the broad ligament is a peritoneal sheet, not a true suspensory ligament.
Identify the cardinal (Mackenrodt's) ligaments as the strongest and most critical for lateral support, making them the 'major' support.
