Summary Introduction

To discuss:

The locations and differences between the upper and lower motor neurons in the descending tracts.

Introduction:

The spinal cord is a collection of nerve tissue that arises from the brain stem. It is a site that contains many motor neurons, interneurons, and complex neural circuits. The spinal cord tracts are stimulatory nerve pathways that pass the information through action potentials. The spinal tracts are important to diagnose and manage the spinal cord damages or injuries. It consists of two kinds of tracts namely ascending tracts (carry sensory information up the cord) and descending tracts (conduct motor impulses down the spinal cord and the brain).
