Question 1: What is a primary neuronal component found in gray matter and in white matter of the central nervous system? What makes the tissue appear gray and white? Where would you expect to see gray matter in a coronal section of cerebral cortex and transverse section of spinal cord? You may state and/or draw your answer.
Question 2: Describe 2 targets of astrocytes within the central nervous system and a distinct function of astrocytes at each of these locations.
Question 3: the human sensory homunculus:
A. Name a region of the body that has a large representation in primary somatosensory cortex compared to the relative size of the body region, and explain the purpose of this large cortical representation in primary somatosensory cortex for a relatively small body region.
For the human motor homunculus.
?B. Name a region of the body that has a large representation in primary motor cortex compared to the relative size of the represented body region, and explain the purpose of a large cortical representation in the primary motor cortex for a relatively small body region.
Name a region that is present in the human sensory homunculus but absent in the motor homunculus, and explain why a region of the body would be represented in the sensory homunculus but not represented in the motor homunculus.
Question 4: Photoreceptors are a class of sensory receptor that is activated by photons of light to convey the conscious sensation of vision.
Name two other classes of sensory receptors and the following details for each of the 2 classes of receptors
A. The primary modality that activates this class of receptors
B. An example of a sensation that is conveyed by their activation.
Question 5:
Describe the contribution of 2 distinct regions of cerebral cortex for language skills. Describe symptoms of damage to each of the 2 regions related to language skills.
Question 6: Describe the 2 distinguishing features of a motor unit and motor neuron pool? Explain why the muscle fibers contained in each are all the same type or a cluster of different types
