The organ system that transmits impulses to muscles to cause contraction is the __ endocrine system skeletal system nervous system

## Step 1<br />The question is asking about the organ system that transmits impulses to muscles to cause contraction. This is a function of the nervous system. The nervous system is responsible for transmitting signals between different parts of the body, and it plays a crucial role in coordinating muscle contractions.<br /><br />## Step 2<br />The endocrine system, on the other hand, produces hormones that regulate various bodily functions, but it does not directly transmit impulses to muscles.<br /><br />## Step 3<br />The skeletal system provides structural support to the body and facilitates movement, but it does not transmit impulses to muscles.
