Senses: Receptors in the Skin

The video explains how the skin detects various sensations such as touch, pressure, heat, pain, and cold through different types of receptors. Thermal receptors detect temperature changes, mechanoreceptors sense touch, and nociceptors detect pain. These receptors are distributed unevenly across the body, with some areas having a higher concentration than others.

Which part of the body is responsible for feeling sensations like cold and heat?

• The heart

• The skin

• The brain

• The muscles

What type of receptors are responsible for detecting temperature changes?

• Photoreceptors

• Mechanoreceptors

• Nociceptors

• Thermal receptors

Where are cold receptors primarily located in the skin?

• Near the bones

• In the hair follicles

• Close to the surface

• Deep in the dermis

Which type of receptors are responsible for sensing touch?

• Thermal receptors

• Nociceptors

• Mechanoreceptors

• Chemoreceptors

In which part of the body are pain receptors more densely packed?

• The legs

• The face

• The arms

• The back
