dendrite

[หˆdษ›n.draษชt ]

Definition

Context #1 | Noun

neuroscience

A dendrite is a short extension of a nerve cell that receives signals from other neurons. These structures play a crucial role in processing and transmitting information in the brain. Dendrites have a high surface area, allowing them to form numerous synapses with other neurons, which enhances the communication between cells. They are essential for learning and memory, as they facilitate the integration of synaptic inputs.

Synonyms

branch, extension.

Examples of usage

  • The dendrites of the neuron received signals from adjacent cells.
  • Dendritic spines can change shape and number, a process essential for learning.
  • The health of dendrites is vital for proper brain function.
  • Damage to dendrites can lead to neurological disorders.

  • Deterioration of dendrites is linked to neurodegenerative diseases like Alzheimer's, affecting brain function.

Art

  • Artists often mimic the intricate patterns of dendrites in abstract designs, showcasing the beauty of nature-inspired forms.
  • The fractal-like appearance of dendrites has inspired various artistic movements, emphasizing interconnectedness.

Origin of 'dendrite'

Main points about word origin

  • The term 'dendrite' comes from the Greek word 'dendron', meaning 'tree'.
  • It was first used in a scientific context in the 19th century to describe the structure of nerve cells.

The word 'dendrite' originated from the Greek word 'dendron' (ฮดฮญฮฝฮดฯฮฟฮฝ), meaning 'tree'. This etymology reflects the branched, tree-like structure of dendrites as they extend from the neuronโ€™s cell body. The term was adopted into scientific vocabulary during the 19th century as researchers began to understand the complex morphology of neurons. The study of dendrites has evolved significantly, particularly with advances in microscopy and neurobiology, allowing scientists to observe and analyze their role in synaptic transmission and neuron connectivity more closely. Understanding dendrites is foundational in neuroscience, as it relates to how information is processed within neural circuits and contributes to higher cognitive functions.
