thermoreceptor

Thân thiện

A scientist explains how a thermoreceptor in the skin detects temperature changes.

Definition

Noun: A specialized sensory nerve ending that detects and responds to changes in temperature, specifically to heat (warmth) and cold.

Usage

A "thermoreceptor" is a biological term for a type of neuron located in the skin and other tissues. Its primary function is to convert thermal energy (temperature) into electrical signals that are sent to the brain, allowing the perception of hot and cold sensations.

Examples

• The thermoreceptors in your skin send signals to your brain when you touch a hot surface.
• Scientists study how thermoreceptors help animals regulate their body temperature.
• A malfunction in certain thermoreceptors can lead to an inability to sense extreme temperatures.

Advanced Usage

• Central thermoreceptors: These are located within the body, such as in the hypothalamus of the brain, and monitor core body temperature to help maintain homeostasis.
• Peripheral thermoreceptors: These are located in the skin and mucous membranes and monitor the temperature of the external environment or the body's surface.

Variants and Related Words

• Thermoreception (n): The sensory process of detecting temperature; the sense of heat and cold.
• Nociceptor (n): A related sensory receptor that responds to potentially damaging stimuli, such as extreme heat or cold that causes pain.

Synonyms

• Temperature receptor
• Thermal sensor (in a biological context)

Related Concepts

• Sensory receptor: The general category of structures that respond to stimuli.
• Homeostasis: The internal stability that thermoreceptors help maintain by providing temperature feedback.
• Hypothalamus: The part of the brain that integrates signals from thermoreceptors to regulate body temperature.
