Tetany and Tremors in Veterinary Medicine Quiz

#1

Which of the following minerals is essential for preventing tetany in animals?

Calcium
Explanation

Prevents muscle spasms by regulating neuromuscular function.

#2

Which neurotransmitter is associated with tremors in animals?

Dopamine
Explanation

Regulates movement and its imbalance can lead to tremors.

#3

Which of the following is a common sign of tremors in dogs?

Excessive salivation
Explanation

Often accompanied by increased drooling.

#4

In veterinary medicine, what is the primary cause of tremors associated with hyperthermia?

Electrolyte imbalance
Explanation

Elevated body temperature disrupts electrolyte balance.

#5

What is the primary cause of tetany in animals?

Calcium deficiency
Explanation

Inadequate 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
Explanation

Occurs during voluntary movements, indicative of neurologic issues.

#7

What is a common symptom of tetany in animals?

Muscle stiffness
Explanation

Muscles contract involuntarily and remain rigid.

#8

Which vitamin is crucial for preventing hypocalcemic tetany in livestock?

Vitamin D
Explanation

Facilitates calcium absorption from the intestine.

#9

Which of the following is a potential trigger for tremors in livestock?

Stress
Explanation

Emotional or physical stress can exacerbate tremors.

#10

In veterinary medicine, what is a common treatment for tetany caused by magnesium deficiency?

Magnesium supplementation
Explanation

Restores magnesium levels to alleviate symptoms.

#11

What role does parathyroid hormone play in the development of tetany in animals?

Promotes calcium absorption
Explanation

Stimulates release of calcium from bones to maintain levels.

#12

In avian species, which vitamin deficiency is associated with tremors and ataxia?

Vitamin E
Explanation

Protects nerve cells from oxidative damage.

#13

Which of the following can be a differential diagnosis for tremors in rabbits?

Thiamine deficiency
Explanation

Leads 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
Explanation

Critical period when calcium demand exceeds intake.

#15

In veterinary medicine, which species is commonly affected by hypocalcemic tetany during parturition?

Cows
Explanation

Due to high demand for calcium during calving.

#16

What is the recommended treatment for tremors caused by lead toxicity in animals?

Chelation therapy
Explanation

Removes lead from the body to alleviate symptoms.

#17

What is the characteristic feature of tetanic spasms in animals?

Sudden and intense muscle contractions
Explanation

Result in powerful, uncontrollable muscle movements.

#18

Which of the following conditions is associated with intention tremor in animals?

Cerebellar dysfunction
Explanation

Damage to the cerebellum disrupts motor coordination.

#19

Which neurological disorder in animals is associated with resting tremors?

Parkinson's disease
Explanation

Causes tremors at rest due to dopamine deficiency.

#20

What is the primary manifestation of tetany in horses?

Twitching of facial muscles
Explanation

Facial muscles exhibit spasmodic contractions.

#21

What is a potential cause of secondary tetany in animals?

Chronic renal failure
Explanation

Impairs kidney function, affecting calcium levels.

#22

Which of the following conditions may lead to tremors in rabbits?

Encephalitozoonosis
Explanation

Caused 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
Explanation

Accumulates 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
Explanation

Prevents nerve signals from reaching muscles, causing tremors.
