• Algostasis — The arrest, blockade, or temporary or permanent suspension of pain sensations; the achievement of analgesia through therapeutic or pharmacological methods. In algology and anesthesia, it describes the clinical stage where nociceptive impulses are interrupted at the synaptic or peripheral level.
• Analgesia — The total absence, complete loss, or pathological or therapeutic diminution of sensitivity to pain, without the loss of consciousness or other sensory modalities (such as tactile or thermal sensitivity). In a structural clinical sense, it can occur as a symptom in severe neurological disorders (like syringomyelia or spinothalamic tract lesions) or can be deliberately induced through the administration of analgesics, local anesthesia techniques, or neurostimulation procedures for patient comfort.
• Anesthetic — A chemical substance, drug, or therapeutic agent that induces a temporary, reversible, and controlled loss of painful, tactile, or thermal sensitivity, either generalized or limited to a specific region of the body. As an adjective, it describes any structural element, procedure, or compound that has the property of canceling the perception of nociceptive stimuli, blocking nerve impulse transmission to the brain.

As an adjective, it describes any structural element, procedure, or compound that has the property of canceling the perception of nociceptive stimuli, blocking nerve impulse transmission to the brain.
• Anodynia — Complete absence of pain or the congenital or acquired inability to feel physical suffering in the presence of an obvious harmful stimulus; absolute analgesia. This rare neurological condition is caused by peripheral receptor dysfunctions, lesions of the spinothalamic tracts, or structural anomalies in the higher nervous centers, exposing the patient to major risks of involuntary self-injury.
• Autoanalgesia — A physiological, neurological, or psychological phenomenon whereby the body spontaneously diminishes, blocks, or suppresses its own perception of physical pain through the internal release of endorphins, enkephalins, or by activating descending inhibitory pathways of the central nervous system, without the administration of external analgesic substances.
