Which of the following is true for diaphragm except(1)muscular structure(2)found in all vertebrates(3)It helps in breathing, urine elimination, and child birth(4)It is dome shaped in normal condition

To determine which statement is not true for the diaphragm, we will evaluate each option:

(1) Muscular structure: This statement is true. The diaphragm is indeed a muscular structure located between the chest and abdominal cavities.

(2) Found in all vertebrates: This statement is also true. The diaphragm is present in all vertebrates, including mammals, birds, reptiles, amphibians, and fish.

(3) It helps in breathing, urine elimination, and childbirth: This statement is true. The diaphragm plays a crucial role in the process of breathing by contracting and relaxing to create changes in thoracic pressure. It also aids in the elimination of urine by assisting in the relaxation of the urinary sphincter. Additionally, during childbirth, the diaphragm helps in the process of pushing the baby out of the uterus.

(4) It is dome-shaped in normal condition: This statement is not true. The diaphragm is actually shaped like a dome when it is at rest or in a relaxed state. However, during inhalation, it flattens and moves downward, allowing the lungs to expand and fill with air.

Therefore, the statement that is not true for the diaphragm is option (4) - "It is dome-shaped in normal condition."
