#nervous system

• Asparagine — A non-essential amino acid, being the first one historically isolated from natural sources (asparagus juice in 1806); it plays a crucial role in human protein biosynthesis, central nervous system metabolism as a neurotransmitter precursor, and in the clearance of toxic ammonia from the body via urea transformation; it is also a key structural compound in the nitrogen metabolism of many higher plants.
• Ataxic — Pertaining to ataxia, characterized by ataxia; suffering from a lack of voluntary coordination of muscle movements due to central nervous system damage. As an adjective, it describes motor behavior, an unsteady or jerky gait, or an organism affected by this pathology; as a noun, it denotes a male patient diagnosed with this neurological condition.
• Ataxia — A neurological disorder manifested by the lack of coordination of voluntary muscle movements, without a reduction in actual muscle strength; the inability to control the direction, precision, and rhythm of fine or gross motor actions. Clinically, it is a symptom or syndrome caused by lesions located in the cerebellum, spinal cord, or deep sensory pathways, affecting balance, gait, and speech.
• Atropism — A chronic pathological condition or systemic poisoning caused by the repeated and abusive use of atropine or other deadly nightshade preparations; a form of dependency or structurally altered tolerance of cholinergic receptors toward the effects of this toxic alkaloid. This phenomenon causes severe functional changes in the autonomic nervous system, manifested through visual, cardiac, and behavioral disorders.
• Autonomic — Relating to the vegetative nervous system, responsible for the automatic and involuntary regulation of vital bodily functions (such as heartbeat, digestion, respiration, or glandular secretions); a structural functional system operating independently of conscious voluntary control. In a clinical sense, it denotes the totality of sympathetic and parasympathetic fibers, ganglia, and reflexes that maintain internal homeostasis in response to environmental changes.
