Step by step
Solved in 3 steps
- The vertebral canal is occupied by a bundle of spinal nerve roots called a. the terminal filum. b.Below L2 the descending tracts. c. the gracile fasciculus. d. the medullary cone. e. the cauda equina.Difficulty maintaining proper posture and balance would MOST likely result from damage to the: Select one: a. ventromedial corticospinal tract b. anterior lateral corticospinal tract c. dorsolateral corticospinal tract d. none of these e. dorsolateral corticorubrospinal tractAfter suffering a stroke, a patient can see objects anywherein front of him but pays attention only to objects in his rightfield of vision. When asked to describe these objects, he hasdifficulty judging their size and distance. What part of thebrain was likely damaged by the stroke?(A) the left frontal lobe(B) the right frontal lobe(C) the right parietal lobe(D) the corpus callosum
- Damage to the surface tissue of the spinal cord will most likely affecta. information processing within the spinal cord.b. the stimulation of sensory organs.c. communication between the peripheral nervous system and the brain.d. reflex arcs.In the spinal cord, the somas of the lower motor neurons are found ina. the cauda equina.b. the posterior horns.c. the anterior horns.d. the posterior root ganglia.e. the fasciculiThe thoracic spinal cord has the smallest dorsal horn area because: a. the trunk is the most innervated area of the body and therefore there are more projections into the dorsal horn there. b. the trunk is the least innervated area of the body and therefore there are fewer projections into the dorsal horn there. c. most of the descending upper motor neurons have already entered the ventral horn. d. There are many motor neurons to control the small muscles around the spine.
- Most fibers of the corticospinal tracta. decussate in the medulla oblongata.b. synapse in the pons.c. descend in the rubrospinal tract.d. begin in the cerebellum.Match the brain area to its correct blood supply superior temporal gyrus Superior frontal gyrus postcentral gyrus gyrus rectus insula inferior temporal gyrus precentral gyrus cuneus and lingual gyrus a. MCA & ACA b. ACA only c. MCA only d. MCA & PCA e. PCA onlyLower limbs are supplied by neurons from the ______ of thespinal cord.a. lumbosacral enlargementb. thoracic regionc. cervical enlargementd. All of these are correct.
- In adults, the spinal cord is not the same length as the vertebral canal, and most of the lumbar part of the spinal cord is within A. the coccyx. B. the sacrum. C. the cervical vertebrae. D. the thoracic vertebrae. E. the cauda equina.Which of the following is part of the hindbrain Question 9 options: A) Pons B) Tectum C) Tegmentum D) Thalamus E) CerebrumA patient presents with paralysis of the right side of the body. A) You know that this patient has suffered brain damage. Explain how you know the damage is to the brain, not the spinal cord. B) What region of the brain is most likely affected? Explain your answer.
