Cranial Nerves: Types Part II01:22

Cranial Nerves: Types Part II

2.4K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

Deglutition01:25

Deglutition

1.9K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Assessment of the Mouth01:26

Assessment of the Mouth

192
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

2.0K
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...

Reflex Activity01:08

Reflex Activity

1.7K
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...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

212
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Area of Science:

  • Neuroscience
  • Speech Science
  • Motor Control

Background:

  • Limited neurophysiological evidence exists for reflex mechanisms in human tongue motor control.
  • Previous studies failed to detect tonic stretch reflexes, questioning reflex contributions.
  • Understanding tongue reflexes is vital for speech production and motor control research.

Purpose of the Study:

  • To provide experimental evidence for a human tongue reflex during speech-related tasks.
  • To investigate the characteristics and functional role of this reflex.
  • To explore the neurophysiological basis of tongue posture stabilization.

Main Methods:

  • Electromyography was used to record muscle activity in the human tongue.
  • A sudden stretch perturbation was applied while participants maintained a speech posture.
  • Computer simulations modeled the muscle activation response and its relation to force generation.

Main Results:

  • A human tongue reflex was detected with a latency of approximately 50 ms, suggesting cortical involvement.
  • Muscle activation peaks were significantly greater during a speech task compared to a non-speech task.
  • The reflex response was not modulated by a voluntary reaction task, indicating its automatic nature.

Conclusions:

  • Reflex mechanisms demonstrably contribute to tongue posture stabilization during speech production.
  • The findings provide crucial neurophysiological evidence for the role of reflexes in tongue motor control.
  • This research advances our understanding of the neural basis of speech articulation.
