Question

the reticular formation contributes to: global cortical arousal and vigilance endocrine gland regulation voluntary muscle control reflex arc modulation

Explanation:

The reticular formation is a network of neurons in the brainstem. It plays a crucial role in regulating global cortical arousal and vigilance. It filters sensory information and helps maintain consciousness. Endocrine gland regulation is mainly by the hypothalamus - pituitary axis. Voluntary muscle control is associated with the motor cortex and pyramidal tracts. Reflex arc modulation is more about spinal cord and local neural circuits.

Answer:

Global cortical arousal and vigilance
