NBSTSA Certified Surgical First Assistant - Exam Topics Sample Questions

The quality of sound that is related to the frequency of the sound waves would be considered which of the following?



Correct Answer:
harmonics
the correct answer to the question regarding the quality of sound that is related to the frequency of the sound waves is "pitch."

sound is a type of energy that travels through the air (or other mediums) as a wave. when discussing sound waves, several characteristics define how we perceive the sound: amplitude, frequency, and timbre. amplitude is related to the loudness of the sound, which is the wave's height. timbre describes the quality or color of the sound, which is influenced by the sound wave's shape and the spectrum of frequencies present. however, it is the frequency of the sound wave that is most directly related to what we perceive as its pitch.

frequency refers to how many times a wave occurs per second and is measured in hertz (hz). a sound wave with a higher frequency will have a higher number of wave cycles per second. this results in a higher pitch, meaning the sound is perceived as more "high-toned." conversely, a lower frequency leads to a lower pitch, making the sound seem "deeper" or "bass-heavy."

it's important to note that while the term "harmonics" also relates to frequencies, it specifically refers to frequencies that are multiples of a fundamental frequency and contribute to the timbre of the sound rather than its pitch directly. harmonics are a component of the sound that enriches its quality but do not solely determine the pitch.

therefore, when we discuss the quality of sound specifically related to how high or low it sounds, we are discussing its pitch, which is directly determined by the frequency of the sound waves.

The tissue in a person’s brain and spinal cord which carries electrical impulses from one part of the nervous system to another would be considered which of the following?



Correct Answer:
white matter


the correct answer to the question is "white matter." the human nervous system is divided into two types of tissue: gray matter and white matter. each type has distinct roles in how signals are processed and transmitted within the brain and throughout the nervous system.

white matter is primarily composed of bundles of myelinated nerve fibers, which are axons covered with a protective layer called myelin. myelin is a fatty substance that gives the white matter its characteristic pale color. the primary function of these myelinated nerve fibers is to transmit electrical signals quickly across different parts of the nervous system. this rapid transmission of electrical impulses allows for efficient communication between the brain and various parts of the body, as well as between different regions of the brain itself.

in contrast, gray matter mainly consists of neuronal cell bodies, dendrites, and unmyelinated axons. it is found in the outer layer of the brain, known as the cerebral cortex, and in various clusters called nuclei deep within the brain. the gray matter is primarily involved in processing and interpreting the information received from the body's sensory systems, and in controlling muscle movements.

therefore, when considering the tissue that carries electrical impulses from one part of the nervous system to another, white matter is the correct answer. it serves as the communication backbone of the nervous system, facilitating the fast and efficient relay of electrical signals across different regions. gray matter, while crucial for processing information and executing commands, does not primarily function in the long-distance transmission of electrical impulses. hence, the role described in the question is specifically characteristic of white matter.
