General Overview of Tracts + Ascending Tracts of Spinal Cord

Here you can learn about general concept of tracts along with first, second, and third order neurons in both ascending tracts and UMN and LMN in descending tracts. The main focus of this video is ascending/sensory tracts. You will learn about function of sensory tracts along with first, second, and third order neurons involved in spinothalamic, spinocerebellar, dorsal column-medial lemniscus, spinotectal, spino-olivary, and spinoreticular tracts. 0:12 Introduction 0:39 Cross section of spinal cord 1:49 Order of neurons in sensory tracts 2:36 Neurons in descending tracts 2:46 Upper Motor Neuron (UMN) 2:58 Lower Motor Neuron (LMN) 3:08 UMN and LMN injury 3:36 Ascending tracts 4:09 Spinothalamic tracts 7:15 Dorsal column-medial lemniscal pathway 9:01 Spinocerebellar tract 10:07 Spinotectal tract 10:35 Spino-olivary tract 10:47 Spinoreticular tract
