Taste Buds and Receptors01:20

Taste Buds and Receptors

4.4K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Vitamins01:30

Vitamins

2.2K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

289
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Disorders of the Nervous Tissue

2.4K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Chronic Kidney Disease II: Clinical Manifestations

491
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

3.5K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Area of Science:

  • Neurology
  • Neuroscience
  • Nutritional Science

Background:

  • Nutritional deficiencies are a common cause of neuropathies encountered by neurologists.
  • Most nutrient deficiency neuropathies are length-dependent sensory axonopathies.
  • Cobalamin deficiency neuropathy is an exception, presenting as a non-length-dependent sensory neuropathy.

Purpose of the Study:

  • To review the patterns and associations of neuropathies linked to nutritional deficiencies.
  • To highlight the unique presentations of cobalamin, copper, and vitamin E deficiencies.
  • To discuss the causes and potential treatments for nutritional neuropathies.

Main Methods:

  • Literature review of neuropathies associated with nutritional deficiencies.
  • Analysis of clinical presentations and diagnostic patterns.
  • Discussion of underlying causes and therapeutic interventions.

Main Results:

  • Cobalamin and copper deficiencies are associated with myelopathy.
  • Vitamin E deficiency is linked to a spinocerebellar syndrome.
  • Pyridoxine toxicity causes a non-length-dependent sensory neuronopathy.

Conclusions:

  • Nutritional neuropathies present with diverse patterns, including length-dependent and non-length-dependent sensory axonopathies.
  • Deficiencies can arise from malnutrition, malabsorption, increased loss, autoimmune conditions, or drug interactions.
  • Early identification and nutrient supplementation can lead to stabilization or improvement of these neuropathies.
