14Which is true about the sensory pathways of the spinal cord
- AThe dorsal columns are responsible for discriminative touch, vibration, and proprioception and the lateral spinothalamic tracts are responsible for pain and temperature.
- BThe dorsal columns are responsible for discriminative touch, pain, and proprioception and the lateral spinothalamic tracts are responsible for vibration and touch.
- CThe dorsal columns are responsible for pain and vibration, and the lateral spinothalamic tracts are responsible for discriminative touch, proprioception and temperature.
15Conscious proprioception receptors are [blank_start]muscle spindles[blank_end], [blank_start]Golgi tendon organs[blank_end], and [blank_start]Pacinian corpuscles[blank_end]
- Amuscle spindles
- BGolgi tendon organs
- CPacinian corpuscles
16The dorsal column pathways is a two-neuron sensory pathway

[blank_start]graciLis[blank_end] - Leg- AcuneAtus
- BgraciLis
20A lesion of the dorsal columns causes [blank_start]ipsilateral[blank_end] deficits in discriminative touch, vibration, and conscious proprioception.
- Aipsilateral
- Bcontralateral
21A lesion involving the ascending sensory information after it has crossed in the brainstem will result in ipsilateral deficits to discriminative touch, vibration, and conscious proprioception
- AVerdadero
- BFalso
22Abnormal sensory perception , such as numbness or tingling, is referred to as [blank_start]paresthesias[blank_end].
- Aparesthesias
23Sharp, localized pain is conveyed by
- Aunmyelinated C fibers
- BLightly myelinated A-delta fibers
24A lesion of the lateral spinothalamic tract will results in deficits in pain and temperature sensation on the [blank_start]contralateral[blank_end] side of the body below the level of the lesion.
- Aipsilateral
- Bcontralateral
25The thalamus is the sensory relay station for virtually all incoming sensory input heading to the cortex
- AVerdadero
- BFalso
26A map of the body along the surface of both the primary motor and somatosensory areas of the cortex is called a [blank_start]homunculus[blank_end].
- Ahomunculus
27On the homunculus, the largest areas (the areas of highest sensory acuity) are:
- Athe lips
- Bthe face
- Cthe fingertips
- Dthe toes
- Ethe hands
28The function of the eye is to focus photons onto the retina
- AVerdadero
- BFalso
29The [blank_start]fovea[blank_end] is the area of highest visual acuity.
- Afovea
- Bmacula
- Cretina
- Dpupil
30As ambiet light increases, the pupils
- Aincrease in circumference
- Bdecrease in circumference
- Cundergo no change in circumference
31When looking at objects off in the distance, the lens
