Which of the following animals is NOT a typical reservoir for the spread of rabies?
- A. dog
- B. bat
- C. skunk
- D. chicken
Correct Answer: D
Rationale: The correct answer is D: chicken. Chickens are not typical reservoirs for rabies as they are not known to carry the rabies virus. Dogs, bats, and skunks can serve as reservoirs for rabies due to their susceptibility to the virus. Dogs are a common source of rabies transmission to humans, while bats and skunks are known carriers of the virus. Therefore, the correct answer is D as chickens do not play a role in the spread of rabies.

The terminal buttons of a neuron are located at the end of its:
- A. axon
- B. dendrite
- C. myelin sheath
- D. nodes of ranvier
Correct Answer: A
Rationale: Terminal buttons, also known as synaptic terminals, are located at the end of a neuron's axon. They contain vesicles filled with neurotransmitters, which are released into the synaptic cleft when an action potential reaches the terminal. These neurotransmitters then bind to receptors on the dendrites of adjacent neurons, facilitating communication between neurons. Terminal buttons are essential for transmitting signals across synapses.
