Work Done on a System by External Force01:11

Work Done on a System by External Force

3.0K
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting particles. The potential energy formulation helps formulate the effect of internal forces. The net work done by an external force can be written in terms of the total change of mechanical energy, which includes both kinetic and potential energies.
In the presence of a non-conservative opposing force, like friction, some part of the work done...

Internal and External Forces01:12

Internal and External Forces

16.2K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

External and Internal Respiration01:24

External and Internal Respiration

7.5K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...

External Anatomy of the Kidney01:21

External Anatomy of the Kidney

3.7K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

External Female Genitals

32.3K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

General External Flow Characteristics01:26

General External Flow Characteristics

538
The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...

Area of Science:

  • Dentistry
  • Oral Pathology
  • Radiology

Background:

  • External cervical resorption (ECR) is an osteoclast-mediated disease affecting dental hard tissues.
  • It presents insidious onset and diagnostic challenges, potentially leading to significant tooth structure loss or extraction.

Purpose of the Study:

  • To systematically review the etiology, pathogenesis, clinical features, classification, diagnosis, and management of ECR.
  • To provide insights for precise clinical decision-making in ECR cases.

Main Methods:

  • Systematic review of literature on ECR.
  • Emphasis on cone-beam computed tomography (CBCT) for diagnosis and staging.
  • Discussion of stepwise treatment strategies based on lesion characteristics.

Main Results:

  • ECR pathogenesis is multifactorial, involving local stimuli, medications, and systemic conditions.
  • CBCT is essential for accurate 3D assessment and staging of ECR.
  • Treatment varies from minimally invasive restoration to extraction, depending on lesion extent and pulpal involvement.

Conclusions:

  • A comprehensive understanding of ECR, supported by advanced imaging like CBCT, enables tailored, stepwise management.
  • Future research should focus on early biomarkers and pharmacological interventions for ECR.
