A plane that separates the body into unequal right and left sides is a:
Correct Answer
E. Parasagittal plane
Explanation
A parasagittal plane is a plane that divides the body into unequal right and left sides. Unlike the midsagittal plane, which divides the body into equal halves, the parasagittal plane creates unequal portions. This plane is commonly used in anatomical studies to examine specific structures or organs that are not located at the midline of the body. It allows for a more detailed analysis of the structures on one side of the body without affecting the other side.

Midway through a 5-mile workout, a runner begins to sweat profusely. The sweat glands producing the sweat would be considered which part of a feedback loop?
Correct Answer
D. Effectors
Explanation
In this scenario, the sweat glands producing sweat would be considered as effectors. Effectors are the parts of a feedback loop that carry out the response to a stimulus. In this case, the stimulus is the runner's increased body temperature due to exercise, and the effectors, the sweat glands, respond by producing sweat to cool down the body and maintain homeostasis.
3.
An unspecialized stem cell becomes a brain cell during fetal development. This is an example of:
Correct Answer
A. Differentiation
Explanation
During fetal development, unspecialized stem cells have the ability to differentiate into specific cell types, including brain cells. This process of differentiation allows the stem cells to transform into specialized cells with specific functions and characteristics. Differentiation is a crucial process in the development and growth of organisms, as it ensures that the different tissues and organs of the body are formed correctly and function properly.

A radiography technician needs to x-ray a growth on the urinary bladder. To accomplish this, the camera must be positioned on the _______ region.
Correct Answer
C. Hypogastric
Explanation
To x-ray a growth on the urinary bladder, the camera needs to be positioned on the hypogastric region. The hypogastric region is located below the umbilical region and is the area where the bladder is situated. This region is the most appropriate for capturing images of the urinary bladder and any abnormalities or growths present in that area. The other options (left inguinal, epigastric, right inguinal, and umbilical) do not specifically target the urinary bladder and are not as relevant for this particular procedure.
5.
Which of the following would not be assoicated with the thoracic cavity?1 - Pericardium 2 - Mediastinum 3 - Peritoneum 4 - Pleura
Correct Answer
C. 3
Explanation
The peritoneum is not associated with the thoracic cavity. The thoracic cavity is the space within the chest that contains the heart, lungs, and other structures. The pericardium is a protective membrane that surrounds the heart, the mediastinum is the central compartment of the thoracic cavity that contains the heart, great vessels, and other structures, and the pleura is a membrane that lines the thoracic cavity and covers the lungs. Therefore, the correct answer is 3, as the peritoneum is not found in the thoracic cavity.
6.
A(n) _________ is a group of similar cells and their surrounding materials performing specific functions.
Correct Answer
tissue
tissues
Explanation
A tissue is a group of similar cells and their surrounding materials performing specific functions.
7.
The sum of all of the body's chemical processes is ________.
Correct Answer
metabolism
Explanation
Metabolism refers to the sum of all chemical processes that occur within an organism's body. It includes the conversion of food into energy, the synthesis of molecules, and the breakdown of waste products. Metabolism is essential for maintaining homeostasis and providing energy for various biological functions. It is a complex and interconnected network of reactions that enables the body to function properly.
8.
The sum of all the body's chemical processes includes the phase that builds up new substsances called _________.
Correct Answer
anabolism
Explanation
Anabolism is the correct answer because it refers to the phase in the body's chemical processes where new substances are built up. This process involves the synthesis of complex molecules from simpler ones, such as the formation of proteins from amino acids. Anabolism is essential for growth, repair, and maintenance of body tissues, and it requires energy input.
