Psychology Terms - Acetic acid
A colorless, smelly liquid that arises during alcohol fermentation and serves as a metabolite of acetylcholine and serotonin. It can be diluted with water to produce vinegar and is extensively utilized in the production of vinyl acetates, polymers, and pharmaceuticals. Acetyl n. The radical group —COCH3 produced by the removal of —OH from acetic acid. [Derived from acetic acid + -yl, denoting a chemical group or radical, from the Greek hyle meaning wood]

Psychology Terms -Acetylcholine
A neurotransmitter released from the terminals of numerous neurons, serving as the primary chemical messenger for motor neurons in the peripheral nervous system, including the autonomic nervous system, and acting as a crucial neurotransmitter in the central nervous system. It functions to stimulate skeletal muscles and inhibit cardiac muscle, persisting only briefly to facilitate the transmission of impulses between cells before being degraded by acetylcholinesterase into acetic acid and choline.

Psychology Terms – Acetylcholinesterase
An enzyme that catalyzes the hydrolysis of acetylcholine into acetic acid and choline. By degrading acetylcholine following its release from the terminal boutons of presynaptic neurons and from postsynaptic receptors after a nerve impulse has been initiated, it inhibits subsequent postsynaptic nerve impulses. Also referred to as cholinesterase. Refer to nerve gas and physostigmine. Abbreviation for Acetylcholinesterase. [Derived from acetylcholine + ester + -ase, indicating an enzyme, from Greek diastasis meaning separation]

Psychology Terms - Achilles tendon reflex
A deep tendon reflex elicited by a tap on the Achilles tendon located in the posterior aspect of the ankle. It is frequently lacking in individuals with diabetes, peripheral nervous system disorders, pyramidal tract diseases, or hyperthyroidism. Also referred to as the ankle reflex.
