The correct answer is Ruffini corpuscles, which are a type of sensory receptor primarily responsible for detecting heat along with sustained pressure and skin stretch. These receptors are located in the deep layers of the skin and in the joint capsules. They respond to the stretching of the skin, which can be associated with heat, thereby contributing to the sensation of warmth.

Merkel cells are mechanoreceptors sensitive to light touch and texture rather than heat. Krause end bulbs are specialized receptors often associated with cold sensation. Pacinian corpuscles are responsible for detecting pressure and vibration, providing insights into mechanical changes rather than thermal sensations. Understanding the specific roles of these different types of sensory receptors is crucial for recognizing how the body senses and responds to various stimuli, including temperature changes.
