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.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
