Muscular control

The effect of high or low environmental temperature on skilled performance is important for industrial or service personnel. Operators often have to work in extreme thermal conditions, such as in furnaces or when they need to operate a pump in cold weather at night. Errors of omission are quite often due to the workers trying to minimize the time period they have to be exposed to high or low temperatures. Particular emphasis has been placed on the effects of cold on manual performance. Cold can affect muscular control, reducing such abilities as dexterity and strength. 

Like alcohol, barbiturates are intoxicating. During the stage after mild intoxication, the person s speech may be slurred. The person may stagger and lose muscular control. Other symptoms of intoxication include irritability, shallow breathing, and fatigue. 

Slight shock felt disturbing but not painful average person can let go however, vigorous involuntary reactions to shocks in this range can cause accidents Painful shock muscular control is lost called freezing or let-go range ... 

The subject is again asked to hold his arm out. Now he is told his arm is becoming rigid, by itself, so rigid that if he tried he wouldn t be able to bend it. Eventually he is challenged to try to bend his arm. In spite of great effort, the arm does not bend he has lost his normal muscular control over it. 

Dysarthria - Imperfect articulation of speech due to disturbances of muscular control which result from damage to the central or peripheral nervous system. 

Its value as a war gas was quickly recognized. Dogs or monkeys poisoned by tabun seemed to lose all muscular control - their pupils shrank to dots, they frothed at the mouth and vomited, they had... 

Caution Combines with the hemoglohin of the blood to form carboxyhemoglobin which is useless as an oxygen carrier. Toxic symptoms Headache, mental dullness, dizziness, weakness, nausea, vomiting, loss of muscular control, increased then decreased pulse and respiratory rates, collapse, unconsciousness, death. Antidote Oxygen. See Patty s Industrial Hygiene and Toxicology vol. 2C, G. D. Clayton, F. E. Clayton, Eds. (Wiley-Interscience. New York, 3rd ed., 1982) pp 4114-4124. 

The rigid cuticle that is the external surface of nematodes is quite distinct from the tegument of cestodes and trematodes. Nematodes also possess a functional gut that ends in a muscularly controlled rectum. Although the various niches occupied by nematodes have led to evolutionary surface adaptations particularly suited for specific environments, the general features of their surface biology are well conserved. 

DTPA diethylene triaminepentaacetic acid DTPA Diethylenetriamine pentaacetic acid dysarthria imperfect articulation of words due to disturbances of muscular control which result from damage to the central or peripheral nervous system dysphagia painful difficulty in swallowing due to disorders affecting the esophagus (gullet), e.g. stenosis (constriction), spasm (cramp)... 

ACUTE HEALTH RISKS headache dizziness mental dullness weakness sleepiness nausea vomiting loss of muscular control increased then decreased pulse and respiratory rates collapse hallucinations methemoglobinemia-carboxhemoglobinemia unconsciousness death by asphyxiation. 

Carbon monoxide is a highly poisonous gas. The acute toxic symptoms include headache, tachypnea, nausea, dizziness, weakness, confusion, depression, hallucination, loss of muscular control, and an increase and then a decrease in pulse and respiratory rate. If the dose is high, these symptoms progress to collapse, unconsciousness, and death. The severity of toxic effects depends on the concentration of carbon monoxide and the duration of exposure. Prolonged exposure to a concentration of 50 ppm does not result in adverse health effects in humans, but a... 

Fig. 9.25. Three possible adaptronic control systems for biomedical applications, a Open-loop solid line) adaptronic system with closed-loop option dashed line), as e. g. applied in the neural/muscular control of a mechanical prosthesis (open-loop) or a drug delivery system (closed-loop), b control depends on two variables, namely the biological system and the ambiance sensor input, c signal is encoded from an ambiance input to achieve an effector response in the biological system. Biosensing delivers state variables for adaptive control...

The majority of the acute studies has been performed on the common lupin alkaloids sparteine and lupanine [39-41]. They both display moderate acute toxicity, the former being the more toxic one. The observed symptoms suggest that alkaloids cause neurological effects leading to loss of motor coordination and muscular control. The effects are generally reversible. 

Milliamperes (women) Painful shock, muscular control is lost. 

EFFECTS OF ALCOHOL. When ingested in moderate amounts, alcohol acts on the central nervous system and higher centers of the brain, lowering inhibitions and affecting judgment. Earge amounts may produce a loss of muscular control, unconsciousness, and even death. Also, people may become addicted to any alcoholic beverage.
