Free-falling Bodies: Introduction01:07

Free-falling Bodies: Introduction

All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is not the case.
Free-falling Bodies: Example01:05

Free-falling Bodies: Example

An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
Body Planes01:06

Body Planes

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...
Composite Bodies00:55

Composite Bodies

A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...
Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Summary

People modify their bodies to meet changing beauty ideals, often influenced by media. Dissatisfaction with body image can cause distress, highlighting the need for practitioners to screen for psychological issues.

Area of Science:

  • Anthropology and Sociology
  • Psychology
  • Cosmetic Science

Background:

  • Human history shows a long tradition of body modification for aesthetic purposes.
  • Cultural, temporal, and geographical factors influence perceived ideal body types.
  • Contemporary media significantly shapes societal beauty standards, often emphasizing youth, slimness, and flawless complexions.

Purpose of the Study:

  • To explore the historical and societal influences on body image ideals.
  • To examine the psychological impact of body dissatisfaction.
  • To emphasize the importance of psychological screening in cosmetic practice.

Main Methods:

  • Literature review of historical and sociological texts on body modification.
  • Analysis of media portrayals of ideal body types.

  • Discussion of psychological implications and diagnostic considerations for cosmetic practitioners.

    • Main Results:

    • Body image ideals are dynamic and culturally constructed, not universal.
    • Societal treatment often favors individuals conforming to conventional attractiveness standards.
    • Body dissatisfaction is linked to significant unhappiness and, in extreme cases, suicide.

    Conclusions:

    • Individuals have the right to alter their appearance, but modifications may not always be beneficial.
    • Cosmetic practitioners must assess clients for psychological factors like unrealistic body image and low self-esteem.
    • Screening for potential psychological disorders, such as dysmorphophobia, is crucial for patient well-being.
