Pelvic Cellular Tissue Functions Analysis

The question asks to identify the correct statements regarding pelvic cellular tissue. Let's analyze each statement:

• Statement 1: It supports the pelvic organs. This is a primary function of the pelvic cellular tissue (endopelvic fascia), providing structural support to organs like the bladder, uterus, and rectum. This statement is correct.
• Statement 2: It forms protective sheath for blood vessels and terminal part of ureter. The cellular tissue embeds and surrounds neurovascular structures and the distal ureters within the pelvis, offering protection and fixation. This statement is correct.
• Statement 3: It prevents infection to be spread out of pelvis. While tissues can sometimes help delineate infection, their primary role is not prevention of spread *out* of the pelvis. Infections can and do spread through these tissues. This statement is generally considered incorrect as a primary function.
• Statement 4: Marked hypertrophy of pelvic cellular tissue occurs in pregnancy. During pregnancy, pelvic tissues, including cellular connective tissue, undergo significant physiological changes, including hypertrophy (enlargement), to accommodate the growing fetus and prepare for labor. This statement is correct.

Selecting the Correct Combination

Based on the analysis, statements 1, 2, and 4 are correct. Therefore, the option including these three statements is the correct answer.

The correct combination is 1, 2, and 4.
