Conduction System of the Heart01:19

Conduction System of the Heart

13.4K
Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

Conduction System of the Heart01:20

Conduction System of the Heart

3.9K
The cardiac conduction system produces and transmits electrical impulses that prompt myocardial contraction, ensuring efficient heart function. This intricate system ensures that the heart beats in a coordinated and efficient manner, beginning with the atria and then the ventricles. The conduction system optimizes cardiac output by maintaining this precise sequence, which is crucial for adequate blood circulation.
This system relies on the unique properties of nodal and Purkinje cells:...

Conduct Disorder01:28

Conduct Disorder

582
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Electrical Conductivity01:13

Electrical Conductivity

1.8K
In perfect conductors, the electric field inside is always zero due to the abundance of free electrons, which nullify any field by flowing. As a result, any residual charge resides on the surface.
In a practical conductor, an applied electric field may be sustained, causing a flow of electrons, which produce a current. The differential form of the current, the current density, is related to the electric field.
More generally, it is related to the force per unit charge, which involves the...

Resistance and Conductance01:25

Resistance and Conductance

517
A conductor's DC resistance at a given temperature is influenced by its resistivity, length, and cross-sectional area. Resistivity is an inherent property of the conductor material, with annealed copper serving as the international standard for measurement. For instance, the resistivity of hard-drawn aluminum at 20 degrees Celsius is 61% of the standard conductivity of annealed copper.
Various factors impact the resistance of a conductor. Spiraling in stranded conductors increases their...

Theory of Metallic Conduction01:17

Theory of Metallic Conduction

1.8K
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...

Area of Science:

  • Neuroscience
  • Audiology
  • Otolaryngology

Background:

  • Vestibular evoked myogenic potentials (VEMP) are muscle responses to auditory stimulation of otolithic organs.
  • VEMP can be elicited by air or bone conduction.
  • External auditory canal occlusion is known to affect cochlear sound perception.

Purpose of the Study:

  • To investigate the presence of the occlusion effect on bone-conducted (BC) cervical VEMPs (cVEMP).

Main Methods:

  • Measured BC-VEMP thresholds and amplitudes in 20 healthy adults.
  • Compared measurements with the external auditory canal open versus occluded.

Main Results:

  • BC-VEMP thresholds were similar in both conditions.
  • Amplitudes were significantly higher with the ear canal occluded (average 76.34μV) compared to open (average 69.9μV).

Conclusions:

  • The occlusion effect is present in cVEMPs, a novel finding.
  • This has clinical implications for evaluating ears with surgical alterations or those using occluding hearing aids.
