NR 414 EXAM 4 questions with correct answers
How many pairs of cranial nerves? Correct Answer-12
How many pairs of spinal nerves? Correct Answer-31
Afferent messages Correct Answer-Sensory messages from the skin to
CNS (from sensory receptors)
Efferent messages Correct Answer-Motor messages from CNS to
muscles and glands
Cerebral cortex Correct Answer-- The center for a human's highest
functions
- Outer 6 layers
- Gray matter
- Responsible for level of consciousness, reasoning, memory
Cerebrum Correct Answer-Right and left hemispheres
Frontal lobe Correct Answer-- Personality, behavior, emotion, intellect
- Initiates voluntary movement
- Broca's area: motor speech (pronouncing words)
- Injury --> change in emotional status, personality
, Temporal lobe Correct Answer-- Auditory reception, taste, smell,
hearing
- Wernicke's area: language comprehension
Parietal lobe Correct Answer-- Sensation, touch, pressure, pain, heat,
cold
Occipital lobe Correct Answer-Visual perception
Thalamus Correct Answer-- Relay station
- Sensory pathways form synapses on way to cerebral cortex
Hypothalamus Correct Answer-- Major respiratory center with basic
function control and coordination
- Thirst, sex, hunger, temperature
Basal ganglia Correct Answer-- Motor-associated with extrapyramidal
tract which controls automatic associated movements (i.e. arm swing
with walking)
- INITIATES gross movement and motor function
Cerebellum Correct Answer-- Motor coordination and muscle tone of
voluntary movements
- FINESSES gross movement (smooth, coordinated, steady)
- Ex: playing piano
