Question
Chapter 49, Problem 5IQ
Summary Introduction
To determine: The functions of primary somatosensory cortex and primary motor cortex.
Introduction: The cerebral cortex is the part of the brain that contains sensory, association, and motor areas. Each side of the cerebral cortex is divided into frontal, temporal, occipital, and parietal lobes.
Summary Introduction
To determine: The distribution of nerve cells in primary somatosensory cortex and primary motor cortex.
Introduction: The outer surface of cerebral hemispheres is referred to as the cerebral cortex. Most of the information processing takes place in the cerebral cortex.

- Which of the following statements best describes the axonal projection patterns of upper motoneurons located in the primary motor cortex? Upper motoneurons located in the primary motor cortex are cholinergic and their axons project directly to muscle fibres to control voluntary muscle movements. Upper motoneurons located in the primary motor cortex are glutamatergic and their axons project to the thalamus, brain stem and directly to muscle fibres to control voluntary muscle movements. Upper motoneurons located in the primary motor cortex project to the spinal cord where they synapse with cholinergic lower motoneurons that control voluntary muscle movements. Upper motoneurons located in the primary motor cortex project to neurons in the cerebellum, thalamus and brain stem that in turn contact lower motoneurons in the spinal cord to control voluntary muscle movements.arrow_forwardWhy are the different regions of the cerebellum involved in this complex motor learning? What might prevent someone from being able to learn to ride a bike? Are there disorders that might prevent this kind of motor function? Is there a correlation between the learning age and the stage of physical development?arrow_forwardWhich of the following statements about the basal nuclei are correct? (SELECT ALL THAT APPLY) a.) The basal nuclei get information from only parts of the cerebral cortex that are involved in movement planning b.) Parkinson's disease is a condition that affects the normal functioning of the basal nuclei c.) The basal nuclei have an indirect pathway that tends to excite and thus increase the activity of the output nuclei (The Globus pallidus internal segment and substantia nigra pars reticulata) of the basal nuclei. d.) The basal nuclei have a direct pathway that tends to inhibit and thus reduce the activity of the output nuclei (The Globus pallidus internal segment and substantia nigra pars reticulata) of the basal nuclei.arrow_forward
