Anatomical Positions01:11

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
Stress Prevention and Stress Management Techniques IV01:26

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...
Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
Muscles of the Vertebral Column01:27

Muscles of the Vertebral Column

The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
Stress on an Oblique Plane01:16

Stress on an Oblique Plane

Understanding stress on an oblique plane under axial loading is pivotal in material mechanics. This analysis offers insight into a material's durability and strength, which is crucial for civil engineering and structural design. Axial loading refers to force application along the material's central axis, causing compression or elongation and leading to normal stress. Normal stress occurs when a force acts perpendicularly to the material's area, resulting in compressive or tensile stress. When...

Area of Science:

  • Biomedical science
  • Human physiology
  • Ergonomics

Background:

  • Posture is defined as the body's spatial position and inter-segment relationships.
  • Correct posture is influenced by a complex interplay of neurophysiological, biomechanical, emotional, psychological, and relational factors.
  • Optimal posture facilitates the performance of daily and occupational activities with minimal energy expenditure.

Purpose of the Study:

  • To define body posture and its determinants.
  • To highlight the importance of correct posture for energy efficiency.
  • To propose posture variation as a preventive measure for prolonged static activities.

Main Methods:

  • Conceptual analysis of posture and its influencing factors.
  • Review of biomechanical and neurophysiological principles related to posture.
  • Ergonomic considerations for maintaining optimal body positioning.

Main Results:

  • Correct posture is multifactorial, involving physical and psychological elements.
  • Efficient posture minimizes energy demands during activities.
  • Posture variation is identified as a key preventive strategy.

Conclusions:

  • Understanding the determinants of correct posture is essential for health and performance.
  • Implementing posture variation can mitigate risks associated with prolonged static postures.
  • This approach supports energy conservation and functional well-being.
