Anatomical Planes & Body Cavities Quiz Questions And Answers

The sagittal plane is a vertical plane that divides the body into right and left halves. This plane runs from front to back and is perpendicular to the ground. It allows for the visualization of structures such as the brain, spinal cord, and internal organs in a side view. The other options are not correct because the transverse plane divides the body into upper and lower halves, the coronal plane divides the body into front and back halves, the oblique plane is at an angle, and the para-sagittal plane is parallel to the sagittal plane.

The transverse plane is the plane that divides the body into superior (upper) and inferior (lower) portions. This plane is perpendicular to the sagittal and frontal planes, and it runs horizontally across the body. It separates the body into two distinct sections, allowing for the examination and analysis of structures and organs in the upper and lower regions of the body.

The abdominopelvic cavity is located below or beneath the diaphragm, making it inferior to the diaphragm.

The midsagittal plane is the only plane that can divide the body into equal halves. This plane passes through the midline of the body, dividing it into left and right halves. The frontal (coronal) plane divides the body into front and back halves, the oblique plane cuts the body at an angle, and the transverse plane divides the body into upper and lower halves. Only the midsagittal plane provides an equal division of the body.

The mediastinum is a space located in the thoracic cavity. It is a central compartment that separates the lungs into two halves and contains vital structures such as the heart, major blood vessels, esophagus, trachea, and thymus gland. Therefore, the correct answer is "Thoracic" as the mediastinum is specifically found within this cavity.

The coronal plane is a vertical plane that divides the body into anterior (front) and posterior (back) portions. It is also known as the frontal plane. This plane is perpendicular to the sagittal and transverse planes, dividing the body into front and back halves. The coronal plane is commonly used in medical imaging and anatomical studies to visualize structures from a front-to-back perspective.

The cranial cavity contains the brain, not any of the options listed. The cranial cavity is a hollow space within the skull that protects and houses the brain. The spinal cord is located within the spinal canal, not the cranial cavity. The liver, uterus, and kidneys are located in the abdominal cavity, not the cranial cavity. Therefore, the correct answer is "None of the above."

The correct answer is mediastinum. The mediastinum is a partition that separates the lungs in the thoracic cavity. It is located in the middle of the chest, between the two pleural cavities. It contains important structures such as the heart, major blood vessels, esophagus, trachea, and lymph nodes. The mediastinum provides support and protection to these vital organs while allowing them to function properly.

The diaphragm is NOT found in the mediastinum. The mediastinum is the central region of the chest, located between the lungs. It contains various structures such as the heart, esophagus, thymus gland, and trachea. However, the diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity and is located below the mediastinum.

The thorax, also known as the chest cavity, is the area surrounded by the rib cage and bounded inferiorly by the diaphragm. It houses vital organs, including the heart and lungs, and provides protection while facilitating breathing. The thorax also contains important structures such as the esophagus and trachea. The diaphragm, a muscle below the thorax, separates it from the abdominal cavity and plays a crucial role in respiration.
