Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

972
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Peripheral Nervous System: Ganglia and Nerves01:24

Peripheral Nervous System: Ganglia and Nerves

2.4K
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...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

11.6K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

918
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...

Nociception01:44

Nociception

29.3K
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.

Area of Science:

  • Neurology
  • Neurosurgery
  • Electrophysiology

Background:

  • Traumatic peripheral nerve injuries (PNIs) present complex challenges in diagnosis, treatment, and recovery.
  • Understanding the epidemiology, classification, and localization of PNIs is crucial for effective patient management.

Approach:

  • This review synthesizes current knowledge on PNIs, focusing on electrodiagnostic (EDx) assessments.
  • Key electrophysiological methods, including nerve conduction studies and electromyography, are discussed for their role in diagnosis and prognosis.

Key Points:

  • EDx assessments are vital for localizing injuries, quantifying axon loss, and guiding treatment decisions in PNIs.
  • Mechanisms of nerve recovery include conduction block resolution, axonal sprouting, and nerve regrowth.
  • Motor recovery from PNIs typically plateaus between 18 and 24 months post-injury.

Conclusions:

  • Optimal outcomes for severe PNIs are achieved with early surgical consultation and intervention, ideally within 3 to 6 months.
  • Awareness of EDx testing timing and interpretation limitations is essential for clinicians managing PNIs.
