Watch this video (http://openstaxcollege.org/l/lumbarpuncture) that describes the procedure known as the lumbar puncture, a medical procedure used to sample the CSF. Because of the anatomy of the CNS, it is a relative safe location to insert a needle. Why is the lumbar puncture performed in the lower lumbar area of the vertebral column?
Which one of the following structures participates in a reflex? a. the gray matter of the brain b. the white matter of the brain c. the gray matter of the spinal cord d. an interneuron that stimulates an afferent neuron e. an interneuron that inhibits an afferent neuron
Watch the video (http://openstaxcollege.org/l/2brains) titled The Man With Two Brains to see the neuroscientist Michael Gazzaniga introduce a patient he has worked with for years who has had his corpus callosum cut, separating his two cerebral hemispheres. A few tests are run to demonstrate how this manifests in tests of cerebral function. Unlike normal people, this patient can perform two independent tasks at the same time because the lines of communication between the right and left sides of his brain have been removed. Whereas a person with an intact corpus callosum cannot overcome the dominance of one hemisphere over the other, this patient can. If the left cerebral hemisphere is dominant in the majority of people, why would right-handedness be most common?
Watch this video (http://openstaxcollege.org/l/neuroexam) that provides a demonstration of the neurological exam—a series of tests that can be performed rapidly when a patient is initially brought into an emergency department. The exam can be repeated on a regular basis to keep a record of how and if neurological function changes over time. In what order were the sections of the neurological exam tested in this video, and which section seemed to be left out?
Thelobe contains the visual cortex frontal parietal temporal occipital
4. The ______________ is the largest tract of commissural fibers in the cerebrum. 5. The ______________ is the pattern of white matter in the cerebellum. 6. The subdural space normally contains cerebrospinal fluid. True or false?
4. Nuclei within the _______ contain the cell bodies of the neurons responsible for sending dopaminergic and serotonergic axons throughout the brain. a. cerebellum b. basal ganglia c. temporal lobe d. spinal cord e. brainstem
8. Which lobe of the cerebral cortex is responsible for auditory perception, speech, and complex visual perceptions? parietal temporal frontal occipital
1. A site of communication between neurons is called a _________ 2. Where is the cerebral spinal fluid found? a.Between the dura mater and the arachnoid mater b.Between the dura mater and the pia mater c.Between the arachnoid mater and the brain d.Between the pia mater and the brain 3. The neuron processes that normally receives incoming stimuli are called _____?
A woman was recently discovered to have lived her entire life (over 20 years) without a cerebellum. What deficits would you expect her to have and why? What traits of the brain allowed her to live a normal life anyway?
1. What is the function of the anterior choroid plexus? 2. What are the adult functions of the optic lobes?
Mr. Jacobs suffers widespread damage to his right cerebral hemisphere. His wife believes he will be fine because his left cerebral hemisphere is undamaged. Is his wife correct? Explain. What deficits, if any, can Mr. Jacobs expect to face?
