- B. Broca's aphasia
- C. Beidecker's aphasia

Correct Answer: B
Rationale: Broca's aphasia is a language disorder that disrupts the ability to speak fluently. Individuals with this condition often experience difficulty in forming complete sentences, finding the right words, and articulating speech. This condition is caused by damage to Broca's area, located in the frontal lobe of the brain, which plays a critical role in speech production and language processing.
After a car accident, Rhodri had a lot of difficulty planning his day. This is most likely the result of damage to which lobe?
- A. temporal
- B. parietal

The frontal lobe also plays a role in personality, social behavior, and motor control, highlighting its importance in complex cognitive processes.
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.
