Question 9 options: Children Adolescents Adults Older adults Question 10 (1 point) What indicates that spinal shock is terminating? Question 10 options: Voluntary movement below the level of injury Reflex emptying of the bladder Paresthesia below the level of injury Decreased deep tendon reflexes and flaccid paralysis Question 11 (1 point) Which term is used to describe a complication that can result from a spinal cord injury above T6 that is producing paroxysmal hypertension, as well as piloerection and sweating above the spinal cord lesion? Question 11 options: Craniosacral dysreflexia Parasympathetic dysreflexia Autonomic hyperreflexia Retrograde hyperreflexia Question 12 (1 point) Why does a person who has a spinal cord injury experience faulty control of sweating? Question 12 options: The hypothalamus is unable to regulate body heat as a result of damage to the sympathetic nervous system. The thalamus is unable to regulate body heat as a result of damage to the sympathetic nervous system. The hypothalamus is unable to regulate body heat as a result of damage to the parasympathetic nervous system. The thalamus is unable to regulate body heat as a result of damage to spinal nerve roots. Question 13 (1 point) Spinal cord injuries most likely occur in which region? Question 13 options: Cervical and thoracic Thoracic and lumbar Lumbar and sacral Cervical and thoracic-lumbar Question 14 (1 point) The most likely rationale for body temperature fluctuations after cervical spinal cord injury is that the person has: Question 14 options: Developed bilateral pneumonia or a urinary tract infection (UTI) Sustained sympathetic nervous system damage resulting in disturbed thermal control Sustained a head injury that damaged the hypothalamus’s ability to regulate temperature Developed septicemia from posttrauma infection Question 15 (1 point) Multiple sclerosis is best described as a(an): Question 15 options: CNS demyelination, possibly from an immunogenetic virus Inadequate supply of acetylcholine at the neurotransmitter junction as a result of an autoimmune disorder Depletion of dopamine in the CNS as a result of a virus Degenerative disorder of lower and upper motor neurons caused by viral-immune factors Question 16 (1 point) What is the most common opportunistic infection associated with acquired immunodeficiency syndrome (AIDS)?

Individuals with bipolar disorder who exhibit psychotic behaviors have deficits in gamma-aminobutyric acid (GABA) linked to genetic loci located on chromosome 20. Individuals with schizophrenia who exhibit psychotic behaviors have deficits in reelin expression linked to genetic loci located on chromosome 18. [Show Less]
