Question

which of the following structures is lateral to the tibia?
○ femur
○ patella
○ fibula
○ phalanges

question 4
which 2 cavities of the body are separated by the diaphragm?
○ ventral and dorsal
○ pelvic and abdominal
○ abdominal and thoracic
○ cranial and vertebral

Explanation:

First Question (Which structure is lateral to the Tibia?):

To determine which structure is lateral (toward the side) to the Tibia, we analyze the anatomical positions:

• Femur is proximal (above) the Tibia, not lateral.
• Patella is anterior (front) to the Tibia - Femur joint, not lateral.
• Fibula is located on the lateral side of the Tibia in the lower leg.
• Phalanges are in the toes, distal (below) the Tibia, not lateral. So Fibula is lateral to the Tibia.

To find the two cavities separated by the diaphragm, we recall anatomical knowledge:

• Ventral and Dorsal are major body cavity divisions (Ventral has thoracic, abdominal, pelvic; Dorsal has cranial, vertebral), not separated by diaphragm.
• Pelvic and Abdominal are both in the ventral cavity and are separated by the pelvic brim, not the diaphragm.
• The diaphragm is a muscle that separates the Abdominal cavity (below) and the Thoracic cavity (above).
• Cranial and Vertebral are in the dorsal cavity, not separated by diaphragm. So Abdominal and Thoracic are separated by the diaphragm.

Answer:

C. Fibula (Note: Assuming the options are labeled as A. Femur, B. Patella, C. Fibula, D. Phalanges as per typical multiple - choice formatting)

Second Question (Which 2 cavities are separated by the diaphragm?):
