Question

this muscle divides the abdominal and thoracic cavities

multiple choice

diaphragm.
pelvik.
diafram.
pelvic.

Explanation:

Identify the anatomical boundary

The question asks for the muscle that divides the abdominal and thoracic cavities. The thoracic cavity is located superiorly, and the abdominal cavity is located inferiorly. The dome-shaped skeletal muscle separating these two cavities is the diaphragm.

Evaluate the spelling of the options

The correct anatomical term is spelled "diaphragm". The option "diafram" is a phonetic misspelling. The options "pelvik" and "pelvic" refer to the lower pelvis region and do not divide the thoracic and abdominal cavities.

Answer:

• (A) diaphragm. (Correct answer)
• (B) pelvik.
• (C) diafram.
• (D) pelvic.
