Disorders of the Nervous Tissue

2.3K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Spinal Cord: Cross-sectional Anatomy

3.6K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Central to the gray matter is...

Nervous Tissue: Myelin01:25

Nervous Tissue: Myelin

4.8K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

Disorders of the Skeletal Muscle

1.5K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Neural Regulation01:37

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Language and Cognition01:27

Language and Cognition

597
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Area of Science:

  • Neuroscience
  • Cell Biology

Background:

  • The central nervous system comprises gray matter (neuronal cell bodies) and white matter (myelinated axons).
  • Historically, gray matter functions received more research focus than white matter.
  • White matter's crucial roles and link to neurological diseases are increasingly recognized.

Purpose of the Study:

  • To review the pathways and functions of myelination in white matter.
  • To explore the relationship between white matter abnormalities and neurological disorders.

Main Methods:

  • Literature review focusing on myelination and white matter function.
  • Analysis of existing research on neurological diseases associated with white matter.

Main Results:

  • Myelination is a key process modulating white matter function.
  • White matter dysfunction is implicated in various neurological conditions.
  • Understanding white matter is vital for comprehending brain function and disease.

Conclusions:

  • White matter plays significant, often underestimated, roles in the central nervous system.
  • Abnormalities in white matter and myelination are linked to numerous neurological disorders.
  • Further research into white matter is essential for advancing neuroscience and clinical neurology.
