Explanation

Blackleg is caused by Clostridium chauvoei, a bacterial infection that produces toxins leading to muscle necrosis.

It mainly affects young cattle.

It is characterized by sudden death and gas-filled swelling in muscles.

Explanation

Norepinephrine is the primary neurotransmitter released by postganglionic neurons in the sympathetic nervous system.

It prepares the body for "fight or flight" responses by increasing heart rate, blood pressure, and alertness.

Explanation

Uterine prolapse in cattle primarily occurs after difficult or prolonged calving, which weakens pelvic muscles and ligaments.

It often follows straining and trauma during delivery, especially in cases of large calf or twin births.

Explanation

Hemorrhagic Septicemia in buffaloes is caused by Pasteurella multocida.

It is a highly fatal bacterial disease causing septicemia and hemorrhages.

Explanation

Cardiac muscle cells have very limited ability to regenerate after injury, leading to scar tissue formation.

Fibroblasts, renal tubular cells, and hepatocytes have a higher regenerative capacity compared to cardiac muscle.

Explanation

Most anesthetics enhance the action of GABA (an inhibitory neurotransmitter) by increasing Cl⁻ ion influx into neurons.

This hyperpolarizes the neuron, making it less excitable and leading to unconsciousness.

Explanation

Intramedullary nailing involves inserting a metal rod into the marrow canal of the bone, offering strong internal support.

It is considered the most effective and stable treatment for long bone fractures like femur or tibia.

Explanation

CPK (Creatine Phosphokinase) is released into the blood during muscle damage, making it a reliable indicator.

It is especially used to diagnose muscle disorders and myocardial infarction.

Explanation

Silent ovulation is when ovulation occurs without visible behavioral signs of estrus in the female.

It often leads to unnoticed breeding cycles, affecting fertility management in animals.

Explanation

Intradermal injection means the drug is injected into the dermis, the layer just beneath the epidermis.

It is commonly used for allergy tests and tuberculosis screening.
