adenodiastasis (s) (noun) (no pl)
Separation or ectopia of glands or glandular tissue from their usual anatomical sites: Examples of adenodiastasis can be the pancreatic glands in the wall of the small intestine, or the gastric glands in the wall of the esophagus.
adiabatic (adjective), more adiabatic, most adiabatic
In thermodynamics, describing a process in which there is no transfer of heat into or out of the system in question: The research indicated that there was an adiabatic loss or gain of heat for the proposed manufacturing of the material.
adiabolist (s) (noun), adiabolists (pl)
A person who denys the existence of the Devil.
adiactinic (adjective) (not comparable)
Referring to the incapability of transmitting actinic rays: Such adjactinic substances do not convey radiation which would damage photochemically sensitive materials, like the safelight in a photographic darkroom.
adiadochocinesia, adiadochocinesis; adiadochokinesia, adiadochokinesis (s) (noun); adiadochocinesias, adiadochocineses; adiadochokinesias, adiadochokineses (pl)
1. Loss of the power to perform rapid alternating movements: This symptom of adiadochocinesia is indicative of a disorder of the cerebellum or its tracts.

Adiadochokinesis involves the inability to stop one movement and then to follow it immediately with another motion in the opposite direction.

2. The inability to perform rapid alternating movements of one or more of the body's extremities: Adiadochocinesis is sometimes requested by physicians during physical examinations so they can determine if the patient has any neurological problems.
3. Etymology: a highly contrived word that is composed of the Greek a-, "without" + diadochos, "successive" + kinesis, "motion".

So, adiadochokinesis is a neurological sign of the inability to perform rapid alternating movements; such as, pronation (turning the hand so the palm faces downward or backward) and supination (having the palm of the hand facing upward).

adiathermancy (s) (noun), adiathermancies (pl)
The condition of being impervious to or unaffected by heat waves: Jake's aunt often experienced adiathermancy and so she didn't find the heat of the desert all that uncomfortable.

Impermeability to heat or not allowing heat to pass through or to diffuse.
