MEDSCI 142 In-course Test Questions
With Complete Verified Solutions.
The medial lemniscus conveys sensory information from where to where? - Answer The gracile and
cuneate nuclei to the thalamus
Which of the following lesions results in a dissociated sensory loss? - Answer A lesion on the right side
of the spinal cord
Which of the following is characteristic of a ventral root of the spinal cord? - Answer Contains
myelinated axons from the lower motor neurons
In deep vein thrombosis, a large cylindrical blood clot forms in a vein of the leg. If the clot breaks free
and begins to move with the blood flow, it is likely to lodge in the: - Answer Pulmonary artery
The wall of his left ventricle, weakened by the presence of an area of dead muscle, ruptures. Blood from
the left ventricle exits through the rupture and enters the pericardial space. As pressure rises in the
pericardial space, it compresses the ventricles and begins to affect the filling of the ventricles during
diastole. If atrial pressure remains the same, which of these is the lowest (pericardial) pressure when
there will be no ventricular filling? - Answer 10 mmHg
A surgeon exposes a human patient's heart by making a midline incision through the skin of the chest,
then cutting lengthwise through the sternum and opening the pericardium. In this view, the chamber of
the heart which she would be LEAST likely to see is the: - Answer Left atrium
Which of the following is incorrect with respect to coronary arteries? - Answer They are elastic arteries
Spinal cord transection at the level of the neck would result in: - Answer Loss of sympathetic control
over stroke volume
An increase in afterload on the heart is most likely to be associated with: - Answer Hypertension
