SENSORY AXON Meaning and
Definition
-
A sensory axon is a specialized neuron that transmits sensory information from the peripheral nervous system (PNS) to the central nervous system (CNS). The sensory axon is responsible for relaying signals from sensory receptors, such as those found in the skin, muscles, joints, and internal organs, to the spinal cord or brain.
The structure of a sensory axon consists of a long, thread-like projection that extends from the cell body of the neuron. This projection, known as an axon, is covered by a myelin sheath, which provides insulation and speeds up the transmission of electrical impulses along the axon. The end of the axon is often branched, allowing multiple connections with other neurons.
Sensory axons are classified based on the type of sensory information they transmit. For example, there are different types of sensory axons responsible for transmitting information related to touch, pressure, temperature, pain, proprioception (sense of body position), and vibration. Each type of sensory axon has specialized receptors at the peripheral end that detect specific stimuli, such as pressure-sensitive receptors or temperature-sensitive receptors.
Once the sensory information is received by the sensory axon, it travels as electrical impulses, called action potentials, along the axon towards the CNS. These action potentials are generated by changes in the electrical charge across the axon membrane, known as depolarization and repolarization. At the CNS, the sensory information is further processed, interpreted, and integrated, resulting in conscious perception and appropriate motor responses.

Etymology of SENSORY AXON
The etymology of the term "sensory axon" can be broken down into its two main components:
1. Sensory: The word "sensory" derives from the Latin word "sensus", which means "feeling" or "perception". It comes from the past participle of the verb "sentire", meaning "to feel" or "to perceive". In the context of a sensory axon, "sensory" refers to nerves or neurons that transmit sensory information from sensory receptors (e.g., in the skin, muscles, or organs) to the central nervous system (brain and spinal cord).
2. Axon: The word "axon" stems from the Greek word "axios", which means "axis" or "axle". It refers to the elongated, slender projection of a neuron responsible for transmitting electrical impulses away from the cell body, often towards other neurons or target cells.
