Functions of the Nervous System

7.6K
The nervous system is responsible for coordinating and regulating the body's functions. It functions through three main processes: sensory, integrative, and motor processes. Sensory function involves the detection and transmission of information about internal and external stimuli from sensory receptors to the CNS. The CNS processes this information through an integrative function, where it interprets and makes decisions based on the incoming sensory information. Finally, the motor function...

Functional Divisions of the Nervous System

8.6K
The nervous system, responsible for sensing, integrating, and responding to various stimuli, is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS has two functional divisions: the sensory or afferent division and the motor or efferent division.
The sensory division transmits information from sensory receptors in the body to the CNS. It provides the CNS with knowledge about somatic senses (such as tactile, thermal, pain, and proprioceptive sensations)...

Magnetic Declination01:19

Magnetic Declination

495
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Area of Science:

  • Neuroscience
  • Rehabilitation Medicine

Background:

  • Central nervous system (CNS) decline, manifesting as cognitive impairment, is a key feature of multiple sclerosis (MS).
  • Current disease-modifying drugs primarily target the immune system but show limited efficacy in improving cognitive performance in MS patients.

Purpose of the Study:

  • To propose exercise as a behavioral countermeasure against CNS structural and functional decline in multiple sclerosis.
  • To highlight the limitations of current MS treatments regarding cognitive function and introduce exercise as a complementary approach.

Main Methods:

  • This article presents a theoretical argument for exercise as a countermeasure for CNS decline in MS.
  • It reviews existing research on the effects of physical fitness, activity, and exercise on cognitive performance and neuroimaging outcomes in MS.

Main Results:

  • A growing body of evidence links physical fitness, activity, and exercise to improved cognitive performance and neuroimaging outcomes in individuals with MS.
  • A strong association exists between cognitive function and neuroimaging results in the MS population.

Conclusions:

  • Exercise is presented as a potential neuroprotective behavior to combat declining CNS function in MS.
  • A framework and future research directions are proposed to further establish exercise's role in managing MS-related cognitive impairment.
