Questions and Answers

What is the primary function of the Peripheral Nervous System (PNS) in terms of impulses and chemical traffic?

  • It receives impulses from the brain and sends them to the Central Nervous System (CNS)
  • It conducts impulses and chemical traffic (correct)
  • It processes and integrates information from the CNS and PNS
  • It regulates the body's response to stress and emotion

    • What is the effect of neural mobilization on neural axon transport?

  • It has no effect on neural axon transport
  • It improves neural axon transport (correct)
  • It decreases neural axon transport
  • It reverses neural axon transport

    • What is the consequence of inflammation of nerves in the nervous system?

  • It results in the formation of scar tissue and increased nerve conduction
  • It leads to demyelination and increased nerve excitability
  • It causes intra-neural fibrosis and decrease of nerve excitability (correct)
  • It has no effect on nerve function

    Study Notes

    Types of Connective Tissues in Nervous System

    • Meninges are a type of connective tissue in the nervous system
    • Axon myelin Schwann cells are another type of connective tissue in the nervous system

    Physiology of Nervous System

    • The Central Nervous System (CNS) sends impulses to the Peripheral Nervous System (PNS)
    • Connective tissues (CT) are continuously connected around all body organs in different shapes
    • Neurons receive impulses from the brain
    • Humans have a high ability to perform skilled movements due to the connection with the nervous system
    • The nervous system not only receives and sends impulses but also has the ability to adapt to various movements and ranges

    Mechanics of Peripheral Nervous System

    • The Peripheral Nervous System (PNS) conducts impulses and chemical traffic
    • PNS is a dynamic tissue
    • PNS can be extremely elongated
    • PNS functions by stretching and sliding as a result of a wide variety of movements

    Spinal Canal Variation

    • The spinal canal varies in size and shape according to the vertebral level and movement
    • C1 vertebra occupies half of the canal, while C5 occupies ¾ of the canal
    • T6 has a narrower and more rounded canal, making it more prone to injury
    • The spine elongates in flexion more than in extension
    • In side bending, the bended side is shortened, and the other side is elongated
    • Changes also occur in spine rotation

    Pathophysiology of Nervous System

    • Direct injury can occur due to tension, overstretching, or compression
    • Indirect injuries can occur due to extra neural injuries, such as soft tissue or fibro-osseous injuries
    • Intra-neural injuries can occur due to inflammation of nerves, leading to changes in connective tissue and decreased nerve excitability
    • Causes of intra-neural injuries include demyelination, hypoxia, scar tissue, and neuroma

    Neural Mobilization

    • Neural mobilization is a manipulative technique that moves and stretches neural tissues by moving relative or surrounding structures
    • Effects of neural mobilization include improving neural axon transport, reducing intra-neural edema, increasing blood flow, and restoring normal mechanisms of connective tissue

    Indications and Contraindications of Neural Mobilization

    • Indications for neural mobilization include any neurological symptoms, unexplained loss of strength, vertebral region injuries, and musculoskeletal injuries
    • Precautions for neural mobilization include spinal stenosis, spondylosis, involvement of other structures, neurological signs, dizziness, general health, and circulatory disorders
    • Contraindications for neural mobilization include acute inflammation and infection, acute neurological signs, worsening of neurological signs, cauda equina, malignant tumors, and injuries to the spinal cord

    Neuro Dynamic Tests

    • Findings on neuro dynamic tests can be classified as optimal, suboptimal, normal, or abnormal

    Relation between Nervous System and Body Movement

    • Neural tissue mobilization requires the body part to be moved with other parts in a neutral position to decrease tension in tissues and move the neutral part
