When an individual displays a deficit in the comprehension of speech involving difficulties in recognising spoken words and converting thoughts into words is known as

Correct Answer: A

Rationale: Wernicke's aphasia is a language disorder characterized by difficulties in understanding spoken language and converting thoughts into coherent speech. Individuals with this condition may produce fluent but nonsensical speech and struggle to recognize spoken words. This condition results from damage to Wernicke's area, a region in the temporal lobe responsible for language comprehension.

Correct Answer: D

Rationale: Sensory neurons in the peripheral nervous system (PNS) transmit nerve impulses from sensory receptors (e.g., in the skin, eyes, or ears) to the central nervous system (CNS), which includes the brain and spinal cord. These neurons play a crucial role in detecting external and internal stimuli, such as touch, temperature, and pain, and relaying this information to the CNS for processing and response.

Correct Answer: A

Rationale: During the repolarization phase of an action potential, potassium ions move out of the axon, restoring the negative charge inside the neuron. This efflux of potassium ions helps return the membrane potential to its resting state after depolarization. The movement of potassium ions is facilitated by voltage-gated potassium channels, which open in response to the change in membrane potential.

Correct Answer: C

Rationale: The brain stem is responsible for regulating unconscious bodily functions, such as breathing, heart rate, and blood pressure. It includes structures like the medulla oblongata, pons, and midbrain. These areas control vital processes necessary for survival and maintain homeostasis. The brain stem also serves as a pathway for nerve signals traveling between the brain and the rest of the body, making it essential for basic life functions.
