This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Special Senses, Subject name: Physiology
The structure that integrates impulses for eye-hand coordination is: 
Select and explain. 
A. Superior colliculus, B. Frontal eye field, C. Pretectal nucleus, D. Area 17
A: Superior colliculus
Answer: A: Superior colliculus 
Explanation: Superior colliculus integrates impulses for eye-hand coordination to control rapid directional movements of the two eyes. VISUAL PATHWAY Other impoant areas of the brain involved in visual pathway: Suprachiasmatic nucleus of the hypothalamus, to control circadian rhythms; Pretectal nuclei in the midbrain, to elicit reflex movements of the eyes to focus on objects of impoance and to activate the pupillary light reflex; Superior colliculus, to control rapid directional movements of the two eyes; and Ventral lateral geniculate nucleus of the thalamus and surrounding basal regions of the brain, to help control some of the body's behavioral functions.
