Summary
Most asymptomatic individuals have cervical lordosis, a spinal curve. This lordotic curvature is more common in males than females and is not linked to age or symptoms.
Area of Science:
- Orthopedics
- Radiology
- Anatomy
Background:
- Cervical lordosis, a critical spinal curvature, exhibits significant variability in reported studies.
- Understanding normal cervical spine curvature is vital for clinical and surgical contexts.
Purpose of the Study:
- To determine the prevalence and degree of cervical lordosis in asymptomatic individuals.
- To investigate the association between cervical lordosis and factors such as age and gender.
Main Methods:
- A systematic literature search and meta-analysis of 21 studies involving 15,364 asymptomatic individuals.
- Random effects meta-analysis and metaregression were employed to assess prevalence, curvature extent, and influencing factors.
Main Results:
- Approximately 64% of asymptomatic individuals exhibited lordotic cervical curvature.
- Lordotic curvature was significantly more prevalent in males than females.
- Age and symptom status did not show a significant association with lordotic cervical curvature.
Conclusions:
- The majority of asymptomatic individuals possess lordotic cervical curvature.
- Cervical lordosis is more pronounced in males compared to females.
- Cervical lordosis is independent of age and the presence of symptoms.

01:09Directing Effect of Substituents: meta-Directing Groups
6.0K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Human behavior is intricately shaped by social influences that arise from interactions with others in diverse contexts. These influences not only mold beliefs and attitudes but also drive the regulation of behaviors through both direct communication and observational learning. The study of these processes falls within the domain of social psychology, which seeks to understand how individuals are affected by and affect those around them.Mechanisms of Social InfluenceDirect social influence...

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

In social psychology, the interplay between individuals and groups is a central concern, particularly regarding how individual actions and characteristics influence group processes and outcomes. While much research emphasizes the group's power in shaping individual behavior, it is equally significant to understand how individuals contribute to the functioning, development, and success of groups.Individual Roles in Group Productivity and Decision-MakingIndividuals are not passive participants in...

Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over...
