Free CMA: Medical Terminology & Anatomy Question and Answers

Question 1

Which of the following would be found in the mediastinum?

Accepted Answer

Aorta

Answer

The mediastinum is the central compartment of the thoracic cavity, located between the lungs. It houses several vital organs and structures, including the heart, great vessels like the aorta, trachea, esophagus, and thymus gland. The aorta, being the largest artery in the body, originates from the left ventricle of the heart and ascends through the mediastinum before arching and descending.

Question 2

When an impulse is transferred from one neuron to another, it happens at:

Accepted Answer

Synapse

Answer

A synapse is the specialized junction where an electrical or chemical signal is transmitted from one neuron to another, or from a neuron to an effector cell like a muscle or gland. This critical point of communication allows nerve impulses to travel throughout the body, enabling functions like thought, movement, and sensation. Neurotransmitters are released into the synaptic cleft to facilitate this transmission.

Question 3

Which of the following terms has the wrong spelling?

Accepted Answer

Bacteriolagy

Answer

The correct spelling for the study of bacteria is 'Bacteriology,' not 'Bacteriolagy.' The suffix '-ology' means 'the study of,' and the root 'bacteri-' refers to bacteria. Recognizing common spelling patterns and suffixes is essential for medical assistants to maintain accuracy in documentation and communication.

Question 4

What is the sequence in which urine moves through the urinary system in a human?

Accepted Answer

Kidney, ureter, bladder, urethra, urethral meatus

Answer

Urine is produced in the kidneys, then travels down the ureters to be stored in the bladder. When the bladder is full, urine exits the body through the urethra and finally out of the urethral meatus. This sequence ensures proper filtration, storage, and elimination of waste products from the body.

Question 5

Which bone is placed below the ischium and above the patella?

Accepted Answer

Femur

Answer

The femur, or thigh bone, is located between the ischium (part of the hip bone) and the patella (kneecap). It is the longest and strongest bone in the human body. The ischium is inferior to the ilium and superior to the patella, placing the femur in the correct anatomical position relative to these structures.
