**Core Concept**
The ligaments of the female pelvis play a crucial role in maintaining the structural integrity and supporting the reproductive organs. One such ligament connects the cervix and fornix to the lateral wall of the pelvis, providing crucial support to the pelvic organs.

**Why the Correct Answer is Right**
The cardinal ligaments, also known as Mackenrodt's ligaments, are a group of ligaments that provide support to the cervix and the upper part of the vagina. They consist of two layers: the transverse cervical ligament and the longitudinal cervical ligament. The transverse cervical ligament connects the cervix to the lateral wall of the pelvis, specifically to the obturator internus muscle and the ischial spine. This ligament plays a vital role in maintaining the anatomical position of the cervix and the upper part of the vagina.

**Why Each Wrong Option is Incorrect**
**Option A:** The uterosacral ligaments connect the cervix to the sacrum, not the lateral wall of the pelvis.
**Option B:** The round ligaments of the uterus connect the uterus to the labia majora, not the cervix or the fornix.
**Option C:** The cardinal ligaments do not connect the cervix to the bladder.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the cardinal ligaments are divided into two layers: the transverse cervical ligament and the longitudinal cervical ligament. The transverse cervical ligament is the stronger of the two and provides the primary support to the cervix and the upper part of the vagina.

**Correct Answer:** C. Uterosacral ligament
