While gathering equipment after an injection, a nurse accidentally received a prick from an improperly
capped needle. To interpret this sensation, which of these areas must be intact?
a. Corticospinal tract, medulla, and basal
ganglia
b. Pyramidal tract, hypothalamus, and sensory
cortex
c. Lateral spinothalamic tract, thalamus, and
sensory cortex
d. Anterior spinothalamic tract, basal ganglia,
and sensory cortex
ANS: C
The spinothalamic tract contains sensory fibers that transmit the sensations of pain,
temperature, and crude or light touch. Fibers carrying pain and temperature sensations
ascend the lateral spinothalamic tract, whereas the sensations of crude touch form the anterior
spinothalamic tract. At the thalamus, the fibers synapse with another sensory neuron, which carries the
message to the sensory cortex for full interpretation. The
other options are not correct.
A patient with a lack of oxygen to his heart will have pain in his chest and possibly in the shoulder, arms,
or jaw. The nurse knows that the best explanation why this occurs is which one of these statements?

its ability to discriminate the location.
