Final answer:
A lesion in the lateral pons or lateral medulla can cause impairments in motor control, reflexes, and sensory functions. It may also affect higher functions like swallowing and recognizing faces.
Step-by-step explanation:
A lesion in the lateral pons or lateral medulla can cause various symptoms depending on the affected structures in the brainstem. It can result in impairments in motor control, such as paralysis or paresis (partial loss of voluntary muscle control), and compromised reflexes. Additionally, it may affect sensory functions, leading to loss of sensation in the face or extremities. Furthermore, a lesion in this region can also impact higher functions, such as the ability to swallow or recognize faces.
