Explanation:

Question 4 (Body Planes)

• 1st Plane: Divides the body into left and right parts (sagittal/median plane).
• 2nd Plane: Divides the body into anterior (front) and posterior (back) parts (frontal/coronal plane).
• 3rd Plane: Divides the body into superior (upper) and inferior (lower) parts (transverse/horizontal plane).

Question 5 (Body Cavities for Surgery)

• 1. Lung Lobe Surgery: Lungs are in the thoracic cavity (part of the ventral cavity).
• 2. Ovary Removal: Ovaries are in the abdominopelvic cavity (part of the ventral cavity).
• 3. Ruptured Disk Surgery: Disks are in the spinal column, so the spinal cavity (part of the dorsal cavity).
• 4. Appendectomy: Appendix is in the abdominopelvic cavity (ventral).
• 5. Gallbladder Removal: Gallbladder is in the abdominopelvic cavity (ventral).

Question 6 (Abdominal Surface Regions)

• 1. Lateral Lower Ribs: Hypochondriac region (overlies lower ribs laterally).
• 2. Belly Button: Umbilical region (surrounds the navel).
• 3. Pubic Area: Pubic (Hypogastric) region (encompasses the pubic area).
• 4. Overlying Stomach: Epigastric region (medial, overlies the stomach).

Question 7 (Bony Landmarks of Abdominopelvic Cavity)

Answer:

1. Sagittal (or Median) Plane
2. Frontal (or Coronal) Plane
3. Transverse (or Horizontal) Plane
