Chapter 54: Care of Patient with Neurologic Disorder (Christensen) -G Flashcards
Name two structural divisions of the Nervous system.
CNS and PNS
The CNS is composed of 2 structures. What are these?
The brain and the spinal cord.
PNS is composed of nerve cells lying outside CNS and has two functional divisions. What are these divisions?
Autonomic and Somatic
This structural division of the Nervous System interprets incoming information and issues instruction based on past experiences
CNS
This functional division of Peripheral Nervous System sends messages to the skeletal muscles (voluntary muscles). What is this?
Somatic Nervous System
Autonomic Nervous System is also called this due to its uncontrollable action.
Involuntary Nervous System
This structure is the functional unit of the nervous system.
Neurons
This structure is composed of axon, cell body and dendrites
Neurons
This part of neuron conducts impulses away form the neuron cell body.
axon
cell body
dendrites
axon
This part of neuron branches from the cell body and receives impulses.
dendrites
This largest part of the brain is divided into left and right hemisphere.
Cerebrum
This structure bridges the left and right hemisphere
gyri
cortex
corpus callosum
corpus callosum
Name 4 Cerebral Lobes
Frontal, Temporal, Parietal, Occipital
This lobe interprets vision!
Occipital
This lobe interprets hearing, smelling, and speech comprehension!
Temporal
This lobe has two areas for speech (motor and written).
Frontal
This lobe has conscious skeletal movement and judgment formation.
Frontal
This lobe interprets sensory impulses from the skin and can also determine distance, size and shape.
Parietal
Cerebrum’s outer portion is composed of gray matter called this.
Sulci
Gyri
Cerebral Cortex
Cerebral Cortex
Injury to Broca’s Area can cause EXPRESSIVE APHASIA which causes inability to speak. Broca’s area is found in this lobe of the cerebrum.
Frontal
Injury to Wernicke’s Area can cause RECEPTIVE APHASIA, in which a person hears a sound but unable to interpret its meaning (ie listening to a foreign language). Wernicke’s are is found in this lobe of the cerebrum.
Temporal
This structure is located at the base of the brain and contains the midbrain, the pons, and the medulla oblongata. This structure’s main function is to carry all nerve fibers between the spinal cord and the cerebrum.
Cerebellum
Basal Ganglia
Brainstem
Brainstem
This second largest structure of the brain lies posterior and inferior to the cerebrum. Voluntary movement coordination and balance, equilibrium, muscle tone maintenance are its main responsibility. What is it?
Interneuron
Cerebellum
Cerebrum
Cerebellum
This structure conducts impulses from and to the brain AND serves as a center for reflex action. In addition, this structure can be 17 to 18 inch long that extends from the brainstem all the way down to 2nd lumbar vertebra. Wicked loongg!!
Basal Ganglia
Midbrain
Spinal Cord
Spinal Cord
The PNS is composed of how many cranial nerves?
12 pairs or 24
The PNS is composed of how many spinal nerves
31 pairs or 62
To maintain homeostasis, the autonomic nervous system has two divisions. These divisions work antagonistic of one another. Ever heard of fight or flight? Yeah, that’s right…
Sympathetic and Parasympathetic
True or False
As neurons are lost with aging, neurologic function deteriorates, resulting in slowed reflex and reaction time.
True
True or False
The incidence of stroke does NOT increase with age.
False
True or False
Cigarette smoking has been found to decrease the incidence nervous system damage due to certain chemicals that keeps the neurons firing.
False. It has been proven that smoking cigarettes causes lung cancer, which in some cases, metastasizes to the brain causing far more damage.
True or False
Trauma or spinal cord injury and head injury occur frequently on young people.
True. Patient teaching on voiding such injuries should include avoidance of drug and alcohol use, safe use of motor vehicle (helmets, seatbelts), safe swimming practices, safe handling and storage of firearms, use of hard hats in dangerous construction areas, and use of protective gear as needed for sports.
