1) The neural tube and neural crest cells are of endodermal origin. FALSE 1) As autonomic motor neurons leave the spinal cord, they synapse with another neuron prior to synapsing with the target organ. TRUE 2) The forebrain develops into the telencephalon and the diencephalon. TRUE 2) There are no sensory neurons associated with the autonomic nervous system. FALSE ?3) A patient is diagnosed with Multiple Sclerosis, which causes a loss of myelination of the axons in the brain. This would interfere with transmission of information between nuclei. 3) Important visceral sensory information like blood pressure, plasma pH, and oxygen concentration are carried to the brain through cranial nerves XI and XII. FALSE 4) The cerebral cortex is composed of superficial white matter with underlying gray matter. FALSE 4) Autonomic motor nerves do NOT innervate ___skeletal muscle_____. 5) Gray matter is found only in the cerebral cortex. FALSE 5) Somatic motor neurons have a direct connection between the CNS and their effector organs, while __autonomic motor______ neurons must synapse on with a peripheral neuron before reaching their effectors. 6) Somatic motor reflexes involve ____ contraction of skeletal muscle_. 6) The midbrain forms from the ___. B) mesencephalon 7) The cerebellum forms from the ________. B) metencephalon 8) Cerebrospinal fluid is found ____. D) Both within the central canal and within the ventricles. Neural crest cells differentiate into __ peripheral nervous system ganglia_. 9) The function of ________ is to link sensory stimuli with the appropriate motor responses. B) interneurons 10) The total percentage of blood flow to the body per minute that goes to the brain is. A) 15 ?11) If the neural tube failed to develop properly, CSF production and circulation could be compromised. 12) Neural stem cells in adult mammalian brains are found in the ________. E) Both the subventricular and subgranular zones. 13) Which area of the brain contains neural stem cells that are apparently important in learning and memory? B) Subgranular zone of the hippocampus

14) Communication between the cerebrum and cerebellum is facilitated by the corpus callosum. FALSE 15) Damage to the parietal lobe of the cerebrum would impair the ability to distinguish between different types of sensations. TRUE 16) Choose the complete list of lobes of the cerebrum. C) Frontal, parietal, temporal, insula, occipital 17) The ________ is a cerebral lobe that is involved in memory and integration of sensory information (mostly pain) with visceral responses. D) insula 18) Choose the statement that characterizes the cerebral cortex. B) Areas of the body with the greatest density of receptors will have larger areas on the somatesthetic cortex. 19) Damage to the temporal lobe of the cerebrum would have the greatest impact on: C) hearing. 20) What type of neurons are found in the precentral gyrus? C) Upper motor neurons 21) What structure separates the frontal and parietal lobes? B) Central sulcus 22) A raised area on the cerebral cortex is a ________. C) gyrus 23) A dysfunction of ________ neurons would limit the ability to learn from and mimic the dance steps of an instructor. D) mirror neurons

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
