HMB200H1 Study Guide - Final Guide: Glasgow Coma Scale, Tectospinal Tract, Rubrospinal Tract
Document Summary
*independent of starting arm position somatotopic organization of motor cortex (like somatosensory cortex) proportional to a-motor neuron innervation of body parts and *not clustered muscles but muscles needed to move body part (which can be further) Descending motor pathways motor cortex spinal cord motor neurons movement of muscles/limbs motor cortex different descending tracts down cord! corticospinal tracts: corticorubral tract rubrospinal tract 2) corticotectal tract tectospinal tract. Loops of data motor cortex sends information to caudate nucleus, basal ganglia other information sent to motor cortex by thalamus (basal ganglia & cerebellum always send through thalamus) and cortex: corticoreticular tract reticulospinal tract. Section 4, chapter 12 neurotransmitters & cell death. *delayed, leaves room for therapies to lessen effects. Glasgow coma scale: measured severity of traumatic brain injury.
