Reflex Activity01:08

Reflex Activity

3.3K
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

2.8K
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...

Somatic Spinal Reflexes

5.3K
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...

The Periodic Table

115.2K
As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Area of Science:

  • Neurology and Psychiatry
  • Clinical Neuroscience
  • Medical History

Background:

  • Ernst Trömner (1868-1930) was a German neurologist and psychiatrist whose work spanned diverse neurological fields.
  • His primary research focus was on muscle reflexes, leading to significant descriptions and modifications of existing reflex tests.

Discussion:

  • Trömner described variants of the Achilles tendon reflex, modified Oppenheim's and Babinski's reflexes, and rediscovered the corneomandibular reflex.
  • He also detailed joint reflexes of the lower extremities and a diaphragmatic muscle stretch reflex.
  • His innovations extended to diagnostic equipment, including the first cerebrospinal fluid sedimentation chamber and the widely adopted Trömner reflex hammer.

Key Insights:

  • Trömner's legacy includes the eponymous Trömner reflex (finger flexor reflex) and the universally recognized Trömner hammer.
  • His contributions extended beyond reflexes to include work on speech disorders, sleep physiology, and neurological manifestations of leukemia.

Outlook:

  • This article provides a concise overview of Trömner's life and contributions.
  • It highlights his impact on clinical neurology and psychiatry, emphasizing work beyond his most famous eponyms.
  • Trömner's innovations continue to influence neurological examination and diagnosis globally.
