Exerts control over other areas such as those responsible for emotions and stress response, and is thought to be the center for self-control, reasoning, and such Motor speech area for control of the muscles of speech A B C Auditory area D E F G Broca’s area H Wernike’s area Language comprehension and elaboration; important for all aspects of language, reading, and speech Cerebellum Responsible for fine motor movements, integration of sensory perception and motor control. I J Spinal Tracts Assignment Name of Tract (3 Sensory, 1 Motor) Information Carried and Destination 1o, 2 o, 3 o with pathway Spinocerebellar Tract Conducts proprioception (muscle sense) from spinal cord to the cerebellum where subconscious senses are perceived 1°= Begins with the unipolar sensory neuron which synapses with the second order neuron in the spinal gray matter 2°= Neuron travels in the spinocerebellar tract to the cerebellum Spinothalamic Tract Conducts pain, temperature, touch, and pressure from the spinal cord to the thalamus and the cerebral cortex where conscious senses are perceived. 1°= Begins with the unipolar sensory neuron from pain, temperature, touch , and pressure receptors 2°= Begins in the spinal gray matter from its synapse with 1° and crosses to the other side of the chord and travels in the tract to the thalamus. In the thalamus, where senses are relayed to the appropriate destinations, the 2°neuron synapses 3°= Neuron travels to the cerebral cortex where the conscious senses are perceived The Fasciculus Cuneatus and Fasciculus Gracilis Conducts discriminative touch and conscious proprioception from spinal cord to the cerebral cortex 1°= Unipolar neurons continue uncrossed to the medulla oblongata where they synapse onto the 2° order neuron 2°= Neurons cross in the medulla and continue on to the thalamus where they synapse with 3° order neurons Corticospinal (Pyramidal) Tract Carries voluntary motor stimuli from ceberal cortex to the spinal cord and the motor neurons which innervate skeletal muscles 3°= Neurons carry the received signals to the cerebral cortex where the sensory signals are interpreted 1°=Begins with multipolar neuron which get its stimuli from the primary motor cortex they pass through the internal capsule and descend to the midbrain where they form the crus cerebri. They then descend to the lateral corticospinal tract. The fibers enter the gray matter where they synapse in the ventral horn and on to 2° neurons. 2°= The latter emerge from the spinal cord in the ventral spinal roots and supply the voluntary muscles through the peripheral nerves.
