Tolerance and withdrawal are pharmacological adaptations, distinct from addiction and from harm.
Body & Medicine·17 connections
The nervous system's detection of damaging stimuli, which is not the same thing as the experience of pain.

Living bone is continuously resorbed and rebuilt, which is why fractures heal and why healing runs in stages.
Body & Medicine·13 connections
Wounds kept moist under an occlusive dressing re-epithelialize faster than wounds allowed to dry and scab.
Holding fractured bone still enough, and aligned well enough, for biology to do the repair.
Body & Medicine·12 connections
A fracture that stops progressing toward healing, usually because of motion, gap or lost blood supply.
Body & Medicine·11 connections
Local anesthetic placed around a nerve or plexus to interrupt conduction from a whole region, and the rebound that follows.
Tissue fed by a single terminal or retrograde vessel has no redundancy, so injury there heals badly.
Most of what is called taste is smell arriving at the receptors from the back of the mouth.
Body & Medicine·10 connections
The claim that pre-industrial night sleep came in two blocks separated by a waking interval, and the dispute over how general that was.
How bodies chemically dispose of foreign compounds, and why those pathways differ enough between species to make one animal's food another's poison.
A family of vitamin-A derivatives that act on nuclear receptors, arranged in a potency ladder that is not a ranking of usefulness.
Body & Medicine·8 connections
The body's stereotyped vascular and cellular response to injury or infection, which is a mechanism, not itself a synonym for infection.
Body & Medicine·7 connections
A stepwise framework for escalating pain treatment in fixed stages, moving to a stronger drug class only once a weaker one fails.
Body & Medicine·5 connections
Pressure trapped inside a closed fascial compartment rises high enough to cut off blood flow to the muscle and nerve sealed inside it.
Pain felt at a site distant from its actual source because the brain misattributes signals that share a nerve pathway.
An internally generated roughly 24-hour cycle in physiology that keeps running even with no external cues to set it.
Body & Medicine·4 connections
Repair tissue built mostly from type I collagen that restores strength to a wound but never rebuilds the original tissue's structure or function.
Both are dense fibrous connective tissue, but a tendon joins muscle to bone while a ligament joins bone to bone.
The physiological maintenance of core body temperature within a narrow range, actively defended rather than passively fixed.
The unconscious sense of one's own body position and movement, running entirely independent of vision.
Body & Medicine·3 connections
The inner ear's sensory system for head position and motion, distinct from hearing despite sharing the same organ.
