SPIDER CELL Meaning and
Definition
-
Spider cell refers to a specialized type of nerve cell, called a neuron, that exhibits a unique morphological structure resembling the legs of a spider. Also known as stellate or astrocytic cells, spider cells are found predominantly in the brain's cerebral cortex and cerebellum, where they play crucial roles in information processing and neural network development.
The distinguishing feature of spider cells is their distinctive star-shaped appearance, characterized by multiple elongated, filamentous extensions that radiate outwards like the legs of a spider. These projections, known as dendrites, enable spider cells to receive incoming electrical signals from neighboring neurons, ultimately integrating and processing this information within the neural circuitry.
Spider cells are responsible for various physiological functions within the central nervous system. They provide structural support and maintain the integrity of neural networks by forming connections with neighboring neurons. They also regulate the chemical environment and the flow of nutrients to neurons, contributing to synaptic signaling and facilitating neural communication. Moreover, spider cells play a vital role in modulating synaptic plasticity, which is essential for learning and memory processes.
Understanding the characteristics and functions of spider cells is crucial for comprehending the complex workings of the brain. Their interactions and integration within the neural architecture provide fundamental insights into the intricate mechanisms underlying cognition, behavior, and numerous neurological disorders.
