Why are nerve impulses an important function in both the special senses and the musculoskeletal system?

Nerve impulse provide signal to brain that controls the body position and position of muscles for movement in case of musculoskeletal system, and in special senses too information is gathered via senses and transmitted in the form of impulse to the brain.

Explanation:

Special senses include: vision, hearing, balance, taste and smell. Sensory receptors are present on these special senses which generates nerve impulse upon external or internal stimulus and this impulse travels to the central nervous system  via sensory nerve and is processed to produce further response.

Musculoskeletal system also have sensory receptors in joints and in muscles that produce nerve impulse, which travel to the brain and provide information about body positions and movements.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
