Equilibrium and Balance01:15

Equilibrium and Balance

8.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System01:29

The Vestibular System

45.6K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Herniated Intervertebral Disc l: Introduction

7
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

4.5K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Viral Meningitis01:18

Viral Meningitis

165
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Veins of Head and Neck01:19

Veins of Head and Neck

7.5K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Summary

Diagnosing cervicogenic vertigo remains challenging, with limited progress in identifying neck disturbances as a cause of dizziness. The cervical torsion test shows promise, but a definitive diagnostic method is still needed.

Area of Science:

  • Neurology
  • Orthopedics
  • Otolaryngology

Background:

  • Cervicogenic vertigo links neck issues to dizziness.
  • Rotational vertebral artery syndrome, whiplash, and cervical degeneration are implicated.
  • Effective diagnostic tools are lacking.

Purpose of the Study:

  • Review recent literature on cervicogenic vertigo.
  • Evaluate diagnostic methods for cervicogenic vertigo.
  • Summarize progress in understanding neck-related dizziness.

Main Methods:

  • Literature review of recent publications.
  • Analysis of case studies and review articles.
  • Assessment of diagnostic test efficacy.

Main Results:

  • Limited new case studies on rare rotational vertebral artery syndrome.
  • Reviews highlight physical therapy and surgical interventions for whiplash/degeneration.
  • Diagnostic methodology publications are scarce and unconvincing.
  • The cervical torsion test shows potential.

Conclusions:

  • Minimal advancement in cervicogenic vertigo research over the past year.
  • The critical issue is the absence of a definitive diagnostic test.
  • A reliable test to link neck disturbances to vertigo is essential for clinical practice.
