What are noxious sensations?

What are noxious sensations?

Noxious stimuli are stimuli that elicit tissue damage and activate nociceptors. Nociceptors are sensory receptors that detect signals from damaged tissue or the threat of damage and indirectly also respond to chemicals released from the damaged tissue.

What is the medical term for noxious stimuli?

Nociception is the neural processes of encoding and processing noxious stimuli. Nociception refers to a signal arriving at the central nervous system as a result of the stimulation of specialised sensory receptors in the peripheral nervous system called nociceptors.

Is pain a noxious stimulus?

A noxious stimulus is actually, or potentially, damaging to tissue and liable to cause pain, but does not invariably do so. Some noxious stimuli, particularly in the viscera, do not cause nociceptive responses.

What detects the noxious stimulus?

What is pain vs nociception?

While nociception refers to neural encoding of impending or actual tissue damage (ie, noxious stimulation), pain refers to the subjective experience of actual or impending harm. Although nociceptive stimulation usually leads to pain, pharmacological and brain lesion research shows that one can exist without the other.

What type of receptors detect pain?

The pain receptors are nociceptors. They are known to exist in muscle, joints, and skin. Each nociceptor has selective sensitivity to mechanical (muscle-fiber stretching), chemical (including lactic acid), and thermal stimuli.

What is brain smudging?

Smudging refers to the changes in the brain areas devoted to detecting the stimulation of body parts and performing functions begin overlapping. This process is why some body parts may become difficult to use or other areas become sensitive compared to the injured area.

What is visceral pain?

Visceral pain is vague and occurs in the abdomen, chest, intestines, or pelvis. It’s experienced due to damage of internal organs and tissues, and it’s not well understood. It’s also not always clearly defined pain, but it is internal pain.
