Speech and language areas are located in:
Correct answer: D. Left cerebral hemisphere
- A. Thalamus
- B. Medulla oblongata
- C. Right cerebral hemisphere
- D. Left cerebral hemisphere
Explanation
The correct answer is the left cerebral hemisphere. This hemisphere is crucial for language and speech functions, containing key areas such as Broca's and Wernicke's areas. These regions are essential for the production and understanding of speech. In contrast, the thalamus serves as a relay station for sensory information, the medulla oblongata manages autonomic functions, and the right cerebral hemisphere is more involved in spatial and non-verbal tasks, not language processing.

About Brain
The brain includes the cerebrum, cerebellum, brainstem, hypothalamus and medulla, each with distinct roles in sensation, movement and homeostasis. Questions connect major brain regions with their functions, reflex control and coordination, while distinguishing involuntary responses from hormonal regulation.
