SENSILLA Meaning and Definition

1. Sensilla refers to tiny sensory organs found in various animals, particularly arthropods. These structures can take the form of specialized hairs, bristles, or pegs, and are distributed on the surface of the animal's body. Sensilla function as sensory receptors, enabling the organism to perceive and respond to various stimuli from its environment.

   Sensilla play a crucial role in the sensory perception of arthropods and are connected to the sensory nervous system. They house nerve cells that are responsible for transmitting signals to the central nervous system, allowing the animal to interpret the stimuli it encounters. Sensilla can respond to a variety of sensory inputs, including touch, temperature, humidity, chemicals (odors or tastes), sound, and even air currents.

   The morphology and structure of sensilla can vary depending on the specific function they serve. Some sensilla are mechanoreceptors, specialized in detecting mechanical stimuli such as touch or vibration. Others are chemoreceptors, designed for sensing chemical compounds in the environment. Some sensilla are even capable of detecting very specific chemicals, allowing the organisms to find food sources or mates.

   Sensilla are important for the survival and behavior of various arthropods, including insects, spiders, and crustaceans. They enable these animals to navigate their environment, locate resources or danger, communicate with each other, and engage in vital aspects of their life cycle.

Etymology of SENSILLA

The word "sensilla" is derived from the Latin term "sensus", meaning "sense" or "sensation". The suffix "-illa" in Latin is a diminutive form, indicating smallness or lesser importance. So, when combined, "sensilla" refers to small sensory organs or structures.
