Nociception01:44

Nociception

28.4K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Ligand-Gated Ion Channel Receptor: Gating Mechanism

4.6K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Neuromuscular Junction And Blockade

5.9K
The site of chemical communication between a motor neuron and a muscle fiber is called the neuromuscular junction (NMJ). The end of the motor neuron at the NMJ divides into a cluster of synaptic end bulbs. The cytoplasm of these bulbs consists of synaptic vesicles enclosing acetylcholine molecules, the principal neurotransmitter released at the NMJ. The region opposite the synaptic bulb that ends in the muscle fiber is called the motor end plate, which has acetylcholine receptors. Within the...

Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.8K
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...

Summary
This summary is machine-generated.

Entrapment and compressive neuropathies around the elbow are common. Magnetic resonance imaging (MRI) aids in diagnosis, especially for space-occupying lesions, complementing clinical and electromyographic evaluations.

Area of Science:

  • Neurology
  • Radiology
  • Anatomy

Background:

  • Entrapment and compressive neuropathies are common clinical conditions affecting nerves around the elbow.
  • Clinical and electromyographic evaluations are often sufficient for diagnosis and management.
  • However, imaging techniques are sometimes necessary for further evaluation.

Purpose of the Study:

  • To discuss compressive neuropathies of the ulnar, median, and radial nerves around the elbow.
  • To emphasize the role of Magnetic Resonance Imaging (MRI) in diagnosing these conditions.
  • To highlight the depiction of normal anatomy and pathological findings using MRI.

Main Methods:

  • Review of clinical and electromyographic findings in nerve entrapment syndromes.
  • Discussion of Magnetic Resonance Imaging (MRI) techniques for evaluating peripheral neuropathies.
  • Correlation of imaging findings with anatomical structures and pathological conditions.

Main Results:

  • Magnetic resonance imaging (MRI) is a valuable tool for evaluating nerve entrapment and compressive neuropathies.
  • MRI is particularly useful for detecting space-occupying lesions that may cause nerve compression.
  • The article details the MRI appearance of normal anatomy and pathological findings for key nerves around the elbow.

Conclusions:

  • MRI is an important adjunctive diagnostic tool for elbow neuropathies when clinical evaluation is inconclusive.
  • Accurate interpretation of MRI findings requires a thorough understanding of normal nerve anatomy.
  • MRI aids in identifying the cause and location of nerve compression, guiding treatment strategies.
