Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves , but there are minor variations in some of the details.
A sensory map is an area of the brain which responds to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation. In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina. In other cases it represents other stimulus properties ...
Late-onset GM2 gangliosidosis may also present as burning dysesthesia. [6] Chemotherapy-induced peripheral neuropathy is a progressive, enduring and often irreversible tingling numbness, intense pain, and hypersensitivity to cold, beginning in the hands and feet and sometimes involving the arms and legs caused by some chemotherapy agents.

A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or sensory functions, for different parts of the body.
Each of these nerves relays sensation (including pain) from a particular region of skin to the brain. The term is also used to refer to a part of an embryonic somite. Along the thorax and abdomen, the dermatomes are like a stack of discs forming a human, each supplied by a different spinal nerve. Along the arms and the legs, the pattern is ...
Experts clear up the confusion on lactic acid, the burning sensation you feel in your legs during hard efforts, how to improve lactate threshold.
Paresthesias are usually painless and can occur anywhere on the body, but most commonly occur in the arms and legs. [1] The most familiar kind of paresthesia is the sensation known as "pins and needles" after having a limb "fall asleep". A less well-known and uncommon paresthesia is formication, the sensation of insects crawling on the skin.
Now, after the lab team’s decade of close collaboration with scientists at Google, that data has turned into the most detailed map of a human brain sample ever created. 300 million images
