Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

Brainstem: Control Centers of Medulla

The medulla oblongata is a crucial part of the brainstem responsible for controlling various autonomic and involuntary functions. It contains several nuclei, including the olivary, cuneate, gracile, and solitary nuclei.
Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...
Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
Physiology of Respiration II: Neurogenic Control of Respiration01:22

Physiology of Respiration II: Neurogenic Control of Respiration

The neurogenic control of respiration coordinates various neural networks and pathways to regulate breathing rate and depth, meeting the body's oxygen and carbon dioxide exchange requirements. This system adapts to physiological and environmental conditions, ensuring optimal breathing patterns.
Central Control
The brainstem is the primary site of central control, hosting respiratory centers:
Reflex Activity01:08

Reflex Activity

A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
A reflex exam is a diagnostic procedure performed by a healthcare professional to evaluate the functionality of a patient's...
The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Area of Science:

  • Neuroscience
  • Respiratory Physiology
  • Pulmonology

Background:

  • Cough is a vital defensive airway reflex.
  • The cough reflex is under significant cortical control, allowing for mimicry and suppression.
  • Reflex cough has a distinct 3-phase motor pattern, also observed in voluntary cough.

Purpose of the Study:

  • To differentiate the motor features of voluntary versus reflex cough.
  • To explore the neural control mechanisms underlying different cough types.
  • To emphasize the diagnostic importance of assessing cough function.

Main Methods:

  • Comparative analysis of voluntary and reflex cough motor patterns.
  • Review of existing literature on cough neurophysiology.
  • Focus on differentiating neural control of respiratory and non-respiratory muscles during coughing.

Main Results:

  • While voluntary and reflex cough share some characteristics, they possess key motor differences.
  • These differences suggest distinct neural pathways govern voluntary and reflex cough.
  • The 3-phase motor pattern of reflex cough is preserved during voluntary coughing.

Conclusions:

  • Voluntary and reflex cough, despite similarities, are controlled by different neural mechanisms.
  • Functional assessment of cough is essential for diagnosing various respiratory and non-respiratory conditions.
  • Further research into the neurophysiology of cough can improve diagnostic strategies.
