#1
Which of the following minerals is essential for preventing tetany in animals?
Calcium
ExplanationPrevents muscle spasms by regulating neuromuscular function.
#2
Which neurotransmitter is associated with tremors in animals?
Dopamine
ExplanationRegulates movement and its imbalance can lead to tremors.
#3
Which of the following is a common sign of tremors in dogs?
Excessive salivation
ExplanationOften accompanied by increased drooling.
#4
In veterinary medicine, what is the primary cause of tremors associated with hyperthermia?
Electrolyte imbalance
ExplanationElevated body temperature disrupts electrolyte balance.
#5
What is the primary cause of tetany in animals?
Calcium deficiency
ExplanationInadequate calcium levels disrupt nerve impulses, leading to spasms.
#6
Which type of tremor is characterized by rhythmic, oscillatory movements and is often seen in neurologic disorders?
Intention tremor
ExplanationOccurs during voluntary movements, indicative of neurologic issues.
#7
What is a common symptom of tetany in animals?
Muscle stiffness
ExplanationMuscles contract involuntarily and remain rigid.
#8
Which vitamin is crucial for preventing hypocalcemic tetany in livestock?
Vitamin D
ExplanationFacilitates calcium absorption from the intestine.
#9
Which of the following is a potential trigger for tremors in livestock?
Stress
ExplanationEmotional or physical stress can exacerbate tremors.
#10
In veterinary medicine, what is a common treatment for tetany caused by magnesium deficiency?
Magnesium supplementation
ExplanationRestores magnesium levels to alleviate symptoms.
#11
What role does parathyroid hormone play in the development of tetany in animals?
Promotes calcium absorption
ExplanationStimulates release of calcium from bones to maintain levels.
#12
In avian species, which vitamin deficiency is associated with tremors and ataxia?
Vitamin E
ExplanationProtects nerve cells from oxidative damage.
#13
Which of the following can be a differential diagnosis for tremors in rabbits?
Thiamine deficiency
ExplanationLeads to neurologic symptoms due to impaired nerve function.
#14
What is the typical age range for the development of tetany in young ruminants?
Newborn to 3 weeks
ExplanationCritical period when calcium demand exceeds intake.
#15
In veterinary medicine, which species is commonly affected by hypocalcemic tetany during parturition?
Cows
ExplanationDue to high demand for calcium during calving.
#16
What is the recommended treatment for tremors caused by lead toxicity in animals?
Chelation therapy
ExplanationRemoves lead from the body to alleviate symptoms.
#17
What is the characteristic feature of tetanic spasms in animals?
Sudden and intense muscle contractions
ExplanationResult in powerful, uncontrollable muscle movements.
#18
Which of the following conditions is associated with intention tremor in animals?
Cerebellar dysfunction
ExplanationDamage to the cerebellum disrupts motor coordination.
#19
Which neurological disorder in animals is associated with resting tremors?
Parkinson's disease
ExplanationCauses tremors at rest due to dopamine deficiency.
#20
What is the primary manifestation of tetany in horses?
Twitching of facial muscles
ExplanationFacial muscles exhibit spasmodic contractions.
#21
What is a potential cause of secondary tetany in animals?
Chronic renal failure
ExplanationImpairs kidney function, affecting calcium levels.
#22
Which of the following conditions may lead to tremors in rabbits?
Encephalitozoonosis
ExplanationCaused by a parasitic infection affecting the nervous system.
#23
Which of the following substances can lead to tremors in animals when ingested in toxic amounts?
Zinc
ExplanationAccumulates in nerve tissue, disrupting function.
#24
What is the primary mechanism of action of neuromuscular-blocking agents that can induce tremors in animals?
Blockade of nicotinic receptors
ExplanationPrevents nerve signals from reaching muscles, causing tremors.
