Block 8 - Our Nervous System LP 3 - Nervous System Analysis

The nervous system allows for fast communication through electric signals that are carried from one nerve to another. The brain coordinates the body's functions by receiving sensory input from different parts and sending motor commands back as signals to parts of the body. Reflex actions are facilitated by the spinal cord and are faster than other actions, helping reduce harm, while the unique human brain distinguishes our species.
