Answer and Explanation:
Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history. Paleontologists are still searching these areas.

The correct answer is - It has to act together with the nervous system mainly with other systems that assist in rock climbing.

Muscular systems involve pulling the weight of an individual towards and leg muscles to hold whereas the nervous system controls or maintain the actions of muscles and also helps in balance the body of the climber. This neuromuscular set helps in maintains the muscle's tonicity in order to execute the action of climbing.
Other than these two main body systems there are cardiovascular system, circulatory system and respiratory system also helps in providing the conditions like increase oxygen input, high heartbeat, and more.
