Muscles of the Thorax01:25

Muscles of the Thorax

The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It originates...

Mechanism of Breathing III: The Accessory Muscles

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
Pulmonary Ventilation: Inhalation01:24

Pulmonary Ventilation: Inhalation

Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.
Boyle's law becomes particularly pertinent when examining respiratory...
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...
Assessment of Ventilation II: Respiratory Depth and Rhythm01:29

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Area of Science:

  • Physiology
  • Biomechanics
  • Neuroscience

Background:

  • The diaphragm and trunk muscles play crucial roles in both respiration and voluntary movements.
  • Understanding their coordinated recruitment is essential for comprehending motor control.

Purpose of the Study:

  • To investigate the recruitment patterns of the diaphragm and trunk muscles during voluntary trunk movements.
  • To analyze the nature of diaphragmatic activity during these movements.

Main Methods:

  • Simultaneous recording of electromyography (EMG) signals from diaphragm and trunk muscles.
  • Video analysis of voluntary trunk movements.
  • Analysis of diaphragmatic EMG during various trunk movements.

Main Results:

  • Diaphragmatic activity duration became irregular during trunk movements.
  • The intensity of diaphragmatic activity increased during voluntary trunk movements.
  • Diaphragmatic activity comprised both respiratory and non-respiratory components.

Conclusions:

  • Diaphragmatic recruitment patterns are altered during voluntary trunk movements.
  • Non-respiratory diaphragmatic activity suggests distinct neural control pathways.
  • Central nervous system likely employs different mechanisms to control respiratory and non-respiratory diaphragmatic functions.
