Thermoreceptors

Thermoreceptors are a type of sensory receptor that are found in the skin, mucosa, skeletal muscles, liver and hypothalamus. They are responsible for the detection of changes in environmental and body temperature.

Types of Thermoreceptors

There are two main types of thermoreceptors:

1. Cold receptors: These are activated by a decrease in temperature. They are found in the epidermis and are more numerous than warm receptors.
2. Warm receptors: These are activated by an increase in temperature. They are found in the dermis.

Function

Thermoreceptors function by sending signals to the brain via the spinal cord when they detect changes in temperature. This allows the body to maintain a stable internal temperature, a process known as thermoregulation.

Clinical significance

Damage to thermoreceptors can lead to a variety of conditions, including hypothermia, hyperthermia, and burns. Additionally, certain diseases, such as multiple sclerosis, can affect the functioning of thermoreceptors.
