Document Summary

3480 lecture 8 -the nervous system topic 2. Divisions of the nervous system: nervous system into the cns and the pns, cns, the brain and the spinal cord, the brain. Subcortical structures (brain stem: pns, somatic division, contains proprioceptive information stretch in the muscles, vestibular structure debate on pns or cns. Neurons and neuromuscular system: alpha motor neuron- has direct connection to extrafusal muscle fibers power producing fibers, this slide is globally depicting a motor unit, an alpha motor neuron and all the extrafusal muscle fibers it innervates. Many different types of neurons: efferent descending neuron conveying motor information, sensory ascending neuron conveying tactile and sensory information. The cerebral cortex and cerebellum: what differentiates humans the size of our cortex and primary frontal cortex. If you look macroscopically at the 2 hemispheres, they look the exact same: they have very different types of functions.
