Renaut Corpuscles or Peripheral Nerve Infarcts? A Historical Overview
Mohamed Kazamel1, Christopher J Boes1
1Department of Neurology,Mayo Clinic,Rochester MN,55905,USA.
Summary
Renaut corpuscles, initially described in European literature, were misidentified as nerve infarcts. This study clarifies their true nature and the historical reasons for this scientific error.
Area of Science:
- Neuropathology
- Peripheral Nerve Anatomy
Background:
- Renaut corpuscles are hyaline structures originating from peripheral nerve perineurium.
- Their accurate description predates their misidentification in English literature.
Observation:
- Kernohan and Woltman (1938) mistakenly identified Renaut corpuscles as "nerve infarcts" in vasculitic neuropathy.
- Krücke (1955) corrected this error, highlighting differential ischemia responses in peripheral nerves versus brain tissue.
Findings:
- This work elucidates the historical evolution of understanding Renaut corpuscle structure and function.
- It explains the scientific error leading to their misclassification.
Implications:
- Clarifying Renaut corpuscle identity is crucial for accurate neuropathological diagnosis.
- Understanding historical scientific errors aids in refining current diagnostic criteria for nerve pathologies.

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.6K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

01:29Overview of Somatic Sensory Pathways
9.2K
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.

01:24Peripheral Nervous System: Ganglia and Nerves
6.8K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

01:30Peripheral Artery Disease I: Introduction
542
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

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...

01:33Somatosensation
44.4K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
