Cross-bridge Cycle01:26

Cross-bridge Cycle

108.8K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

2.1K
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...

Multiple Sclerosis l: Introduction

20
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Alzheimer Disease ll: Pathophysiology

35
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and...

Parkinson Disease ll: Pathophysiology

28
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Myasthenia Gravis ll: Pathophysiology01:22

Myasthenia Gravis ll: Pathophysiology

53
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...

Summary
This summary is machine-generated.

Neuronal damage, not just demyelination, drives brain atrophy and long-term disability in multiple sclerosis (MS). Understanding these neuronal pathologies is key to managing MS progression.

Area of Science:

  • Neuroscience
  • Immunology
  • Pathology

Background:

  • Multiple sclerosis (MS) pathology increasingly recognized to involve neuronal damage.
  • Neuronal loss contributes significantly to early and progressive brain atrophy in MS.
  • Chronic neuroinflammation exacerbates axonal and neuronal loss, impacting long-term patient disability.

Purpose of the Study:

  • To review key findings on neuronal pathology in multiple sclerosis.
  • To elucidate the mechanisms linking immune attack to neuronal damage.
  • To identify major pathological correlates of brain atrophy in MS.

Main Methods:

  • Literature review of recent findings on MS pathology.
  • Analysis of direct axonal damage processes.
  • Examination of demyelination-related and cell-body pathology.

Main Results:

  • Neuronal pathology is a primary driver of brain atrophy in MS.
  • Direct axonal damage and demyelination-related pathology contribute to neuronal loss.
  • Cell-body pathology is also a significant correlate of brain atrophy.

Conclusions:

  • Neuronal damage is a critical, previously underestimated, component of MS.
  • Understanding the pathways from immune attack to neuronal injury is crucial.
  • Identifying pathological correlates of brain atrophy can inform MS management and treatment strategies.
