thermoreception in polar bears

Cold-blooded animals such as lizards maintain safe body temperatures by moving into locations of favourable temperature. This behaviour is largely influenced by thermoreceptors in the skin.

Diagram of the autonomic nervous system showing the sympathetic and parasympathetic divisions. The left side illustrates sympathetic nerves branching from the spinal cord to organs and glands, while the right side shows parasympathetic nerves connecting to organs such as the eye, heart, lungs, liver, stomach, intestines, and bladder. Color-coded pathways and labeled ganglia highlight the different nerve routes and target organs in human anatomy.

Imaging technologies such as positron emission tomography (PET) have become valuable tools in the study of human sensation. For example, PET has been used to investigate brain areas involved in thermoreception.
