The correct answer is c. having a partner help you stretch by flexing and relaxing the muscle.
Proprioceptive neuromuscular facilitation (PNF) stretching involves a partner-assisted stretching technique that involves both active and passive movements. The partner helps the individual to stretch a specific muscle group by applying resistance while the individual contracts the muscle. After the contraction, the partner then assists in stretching the muscle further than the individual could achieve alone. This process is repeated several times to achieve a greater range of motion.
PNF stretching is considered an effective stretching method as it targets both the muscle and the nervous system. It is useful for increasing flexibility, improving range of motion, and reducing muscle tension. PNF stretching can be used for both pre-exercise warm-up and post-exercise recovery.
Option a (holding a stretch at the point of discomfort) and option d (stretching by holding a position for 10-30 seconds) describe static stretching techniques, while option b (using a bouncing motion while stretching) describes ballistic stretching, which is not recommended due to the increased risk of injury.

This research study is an example of a(n experimental study.
Experimental studies involve manipulating an independent variable (in this case, the treatment) to observe its effect on a dependent variable (the outcome being measured). In this study, the treatment group received the treatment, while the control group received a placebo, which is a substance with no therapeutic effect. By comparing the outcomes between the two groups, researchers can determine whether the treatment had a significant effect.
Experimental studies are considered the gold standard for testing causal relationships between variables, as they allow researchers to control for extraneous variables that could potentially affect the results. However, they also have some limitations, such as ethical considerations, practical limitations, and the difficulty of replicating real-world conditions in a laboratory setting.

T/F cementum helps to anchor teeth in their sockets.
Cementum is a specialized calcified tissue that covers the root of the tooth, forming a thin layer over the dentin,the correct answer is True.
Its primary function is to anchor the tooth to the jawbone by attaching the periodontal ligament fibers to the tooth's root surface.
Without cementum, teeth would be unable to remain firmly attached to the socket and would eventually loosen or fall out.
Cementum also serves as a protective layer for the root surface, providing a barrier against external stimuli and bacterial invasion.
It is a unique tissue in that it is formed throughout life, unlike dentin and enamel, which are formed only during tooth development.
Cementum contains various cell types and organic and inorganic components that play a crucial role in tooth support and maintenance.
In summary, cementum is essential in anchoring teeth in their sockets and providing protection to the root surface. Its formation and maintenance are critical to maintaining healthy and functional teeth throughout life.

which is a network of fibers that attach the tooth to its surrounding bone. Cementum also serves to protect the root of the tooth by providing a barrier against bacteria and other harmful agents.Cementum also plays a role in providing a lubricating surface to help reduce friction during chewing and other activities. In addition, cementum helps to protect the root of the tooth, which can be vulnerable to abrasion and erosion. It is composed of collagen and other organic molecules, and its main function is to help anchor teeth to the alveolar bone in the jaw.

Amalgam fillings should be avoided during pregnancy due to the presence of mercury, and white resin composite fillings are preferred as they are believed to be safer for both pregnant and breastfeeding women.
The most true statement about amalgam (silver and mercury) fillings placed during pregnancy is that they are safe in pregnancy, but there are risks associated with placement of all types of fillings, not just amalgam fillings. It is important for pregnant women to discuss with their dentist about the risks and benefits of any dental treatment, including fillings, and to consider alternatives such as white resin composites if desired.
There is no evidence to suggest that amalgam fillings should be avoided during pregnancy, but some dentists may prefer to use white resin composites as an alternative, which are believed to be safe during pregnancy and breastfeeding. The decision of which type of filling material to use should be made on a case-by-case basis, taking into account the individual patient's dental needs, medical history, and preferences.

A 50 year-old patient has a mass removed from his chest. The surgeon sends it to pathology. The pathology report indicates the mass is a benign tumor.
What ICD-10-CM code is reported?
A) D36.7
B) D49.2
C) C79.89
D) C49.3
The correct ICD-10-CM code to report is: D36.7 - Benign neoplasm of other specified sites. The correct option (A).
To determine the correct ICD-10-CM code for a 50-year-old patient who had a benign tumor removed from his chest, let's consider the options provided:
A) D36.7 - Benign neoplasm of other specified sites
B) D49.2 - Neoplasm of unspecified behavior of bone, soft tissue, and skin
C) C79.89 - Secondary malignant neoplasm of other specified sites
D) C49.3 - Malignant neoplasm of connective and soft tissue of thorax
Since the pathology report indicates the mass is a benign tumor, we can eliminate options C and D, as they are malignant neoplasms. Between options A and B, option A (D36.7) is the most appropriate, as it specifically addresses benign neoplasms in other specified sites, which in this case, is the chest.
