Insights

Damage to the corticospinal system (CS) and peripheral nervous system (PNS) in early life can impair upper extremity function. Understanding these systems is key for motor rehabilitation.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Clinical Neurology

Background:

  • The corticospinal system (CS) and peripheral nervous system (PNS) are crucial for motor control.
  • These systems are vulnerable to damage during prenatal and early postnatal development.
  • Impairments in CS and PNS development can lead to significant functional deficits.

Purpose of the Study:

  • To review the developmental features of the CS and PNS.
  • To examine the clinical consequences of CS and PNS damage on upper extremity (UE) function.
  • To highlight the importance of these systems for UE motor capabilities.

Main Methods:

  • Literature review of developmental neuroscience and clinical neurology studies.
  • Synthesis of information on CS and PNS development and injury.
  • Analysis of the impact on upper extremity function.

Main Results:

  • Proper development of both CS and PNS is essential for adequate UE function.
  • Injury or abnormal development of these systems can result in UE dysfunction.
  • Such dysfunction can limit participation in daily living activities.

Conclusions:

  • The PNS and CS are critical for proper UE functioning.
  • Further understanding of their developmental roles and disorders is necessary.
  • This knowledge is vital for advancing the rehabilitation of motor impairments.

Neurogenesis and Regeneration of Nervous Tissue

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...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
