Study Notes
Chapter 11 Homework Assignments - Study Notes
Bloom's Level 1
-
Homework Assignment 11.1: The central nervous system (CNS) includes the cerebral cortex, white and gray matter, and the reticular formation. Dorsal root ganglia are outside the CNS.
-
Homework Assignment 11.2: The primary motor cortex is located in the frontal lobe, and the primary visual cortex is located in the occipital lobe.
-
Homework Assignment 11.3: The hypothalamus is part of the diencephalon.
-
Homework Assignment 11.4: Blood reaches the brain through the internal carotid arteries.
-
Homework Assignment 11.5: Ascending or descending spinal cord tracts are named for the region where they begin and end within the CNS.
-
Homework Assignment 11.6: Cranial nerve IV (trochlear) innervates the superior oblique eye muscle.
-
Homework Assignment 11.7: Cerebrospinal fluid (CSF) is a clear watery fluid produced by ependymal cells. It cushions the brain and spinal cord and has a similar composition to plasma, but less protein.
-
Homework Assignment 11.8: The vagus nerve (cranial nerve X) has sensory, motor, and parasympathetic fibers, and plays no role in eye regulation.
-
Homework Assignment 11.9: A simple reflex arc follows this pathway: receptor → afferent neuron → interneuron → efferent neuron.
-
Homework Assignment 11.10: Cell bodies for the fasciculus gracilis and cuneatus tracts are located in the dorsal root ganglion.
-
Homework Assignment 11.11: The Babinski reflex uses afferent pathways, involves the peripheral nervous system, and can be used to diagnose nervous system dysfunction in newborns.
-
Homework Assignment 11.12: The order of tissues in a nerve, from the outside moving inward, is epineurium, perineurium, endoneurium, axon.
Bloom's Level 2 (and 3 - with some overlap in these questions)
-
Homework Assignment 11.13: Compounds like CO2, O2 and glucose can pass through the blood-brain barrier. Fat-soluble compounds can cross the barrier directly, others require transporters like glucose GLUT transporters.
-
Homework Assignment 11.14: A false statement about the CNS is that dorsal root ganglia are part of the CNS. They are part of the peripheral nervous system.
-
Homework Assignment 11.15: A convergent neuronal circuit is exemplified by information processing in the visual system.
-
Homework Assignment 11.16: Proof that the left side of the brain receives information about the right side of the body is given by contralateral ascending fibers into the thalamus.
-
Homework Assignment 11.17: Occlusion of the carotid artery is dangerous because the brain has a narrow safety margin for oxygen, supplied by the carotid arteries. The carotid arteries are the primary blood supply to the brain.
-
Homework Assignment 11.18: Spinal cord-injured patients face challenges because the connections between spinal cord motor neurons and muscles depend on synaptic activity. Muscles atrophy without consistent stimulation.
-
Homework Assignment 11.19: Connections between axons and target cells are formed during fetal development because of the presence of cues or signposts in the fetus that guide the axons to their target cells, this process does not occur in adulthood.
Bloom's Level 5
-
Homework Assignment 11.20 + 11.21 + 11.22+ 11.23 (not included): These assignments are not included as they involve higher-order analysis and are not summarized in a factual manner.
-
Homework Assignment 11.20 (partial): Christina, from Oliver Sacks' "The Man Who Mistook His Wife for a Hat," had symptoms of an inability to sense the position of her limbs in space due to sensory neuritis affecting proprioceptors.
