DANB's Certified Restorative Functions Dental Assistant - Additional Info Sample Questions

Tray compound has which of the following characteristics that differs from impression compound?

Correct Answer:
tray compound is stiffer

tray compound and impression compound are both used in dental procedures but serve different purposes and have distinct characteristics. one of the primary differences between the two is their stiffness. tray compound is notably stiffer than impression compound. this difference in stiffness is crucial because each compound is tailored to meet specific requirements in the dental impression process.

tray compound is primarily used for constructing custom impression trays. these trays are foundational tools used by dentists to accurately capture the dimensions and structures of a patient's mouth. the stiffness of tray compound is beneficial here because it provides a firm and stable framework for the impression material, which will later be used to record fine details of the dental structures. the rigidity of the tray compound ensures that the tray holds its shape during the impression process, preventing any distortion that could affect the accuracy of the mold.

in contrast, impression compound is designed to be somewhat pliable and less stiff. this characteristic is essential for it to effectively capture the precise contours and details of teeth and gums. impression compounds must flow into and fill all the nooks and crannies of the dental and gingival structures, registering detailed impressions that are vital for creating accurate dental appliances.

furthermore, the stiffness of tray compound means it is less likely to sag or deform under the weight of the impression material. this stability is crucial during the impression-taking process, as any deformation can lead to inaccuracies in the final dental product, such as dentures, crowns, or bridges. in summary, the stiffer nature of tray compound compared to impression compound is integral to its role in creating a solid, dependable base for detailed dental impressions.

A muscle’s ability to stretch best demonstrates:

Correct Answer:

the correct answer to the question regarding which characteristic of muscle tissue is best demonstrated by its ability to stretch is "extensibility." this property of muscle tissue is one of several key functional characteristics that define the behavior of muscles in response to various stimuli and during physical activity.

to elaborate on these characteristics: - **extensibility:** this refers to the ability of muscle tissue to stretch or extend. muscles must be capable of extending within their normal functional range in order to accommodate the movements required for daily activities and exercise. extensibility is crucial not only for motion but also for helping to prevent injuries by allowing muscles to adapt to stretches without being harmed.

other related characteristics include: - **excitability:** this property enables muscle tissue to respond to stimuli, primarily neurotransmitters released by nerve endings. excitability is the capacity of muscle cells to respond to these signals by creating electrical impulses, which are necessary for initiating contraction and other cellular processes. - **contractibility:** this is the ability of muscle tissue to contract forcefully when stimulated by a nerve impulse. contracting muscle fibers pull on the bones they are attached to, thereby generating movement. contractibility is a fundamental property that allows muscles to fulfill their primary function of producing force and movement. - **elasticity:** after being stretched or contracted, muscle tissue exhibits elasticity by returning to its original resting length. this elastic property helps maintain muscle integrity and ensures that muscles are not permanently deformed after elongation or contraction.

in summary, while excitability, contractibility, and elasticity are essential properties for muscle function, it is extensibility that specifically allows muscle tissue to stretch effectively. understanding these properties provides insights into how muscles operate and interact with the skeletal system to facilitate body movements.
