Chapter 5, Problem 1SRQ

Summary Introduction

Introduction: A flat surface that results from an imaginary or a real cut through the body in normal anatomical position is called body plane. An individual in anatomic position stands erect, with feet parallel, arms at the sides, and eyes and palms facing forward.

Answer to Problem 1SRQ

Correct answer: “The transverse plane divides the body horizontally into upper and lower portions”.

Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Option b. is given as “horizontally into upper and lower portions”.

The transverse plane is also called as axial plane or horizontal plane. The body is divided horizontally into upper and lower portions by transverse plane. The transverse plane is perpendicular to the coronal plane and sagittal plane.

Hence, option b. is correct.

Reasons for incorrect statements:

Option a. is given as “diagonally into upper and lower portions”.

The midsagittal plane divides the body diagonally into upper and lower portions.

Hence, option a. in incorrect.

Option c. is given as “vertically into front and back portions”.

Frontal plane divides the body vertically into front and back portions.

Hence, option c. is incorrect.

Option d. is given as “vertically into right and left portions”.

Sagittal plane divides the body vertically into right and left portions.

Hence, option d. is incorrect.

Hence, options a., c., and d. are incorrect.

Conclusion

The transverse plane divides the body horizontally into upper and lower portions.
