○ protection from blows
○ nourishment of the brain
○ initiation of some nerve impulses

identify the answer that describes the nervous system integrative function.
○ senses changes in the environment
○ analyzes sensory information, stores information, makes decisions
○ responds to stimuli by gland secretion or muscle contraction

Explanation:

First Question (Functions of CSF):

CSF (Cerebrospinal Fluid) functions include reducing brain weight (by buoyancy), protecting from blows (cushioning), and nourishing the brain (supplying nutrients). Nerve impulses are initiated by neurons, not CSF. So the function not of CSF is initiation of some nerve impulses.

The integrative function of the nervous system involves analyzing sensory info, storing it, and making decisions. Sensing changes is sensory function, and responding via glands/muscles is motor function.

Answer:

initiation of some nerve impulses
