Which of the following is an example of the endocrine system directly interacting with the nervous system ?

a) the vertebrae protect the spinal cord from injury.

b) hormones provide feedback that affects neural processing.

c) sensory receptors in bones send signals about body position to the brain.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
