NR 412 Exam 2 (Acid/Base, Pulmonary, Somatosensory) Questions With Complete Solutions

BIO 210 Lecture Exam 4 Questions and Answers 100% Pass A posterior root contains A) sensory axons only B) motor axons only C) a mix of sensory and motor axons D) autonomic nervous system axons A) sensory axons only The white matter of the spinal cord is surrounded by gray matter. A) True B) False B) False If a patient experiences numbness in the boundaries of a dermatome, it is suggestive of damage to A) the somatosensory cortex B) the thalamus C) one of the spinal ...

RAPID-adapting mechanoreceptors - ️️Meissner and Pacinian (dynamic phase QUICKLY becomes static phase) dorsal root ganglion (DRG) - ️️(part of the PNS) cluster of cell bodies in the dorsal root of a spinal nerve (when the action potential reaches the DRG, it splits into 2 - one travels toward the cell body and the other continues down the axon) dorsal horn - ️️the POSTERIOR column of grey matter in the spinal cord (shape differs depending on spinal segment) - contains SENSORY n...

dermatome - ~~> the area of skin supplied by the sensory axons of a single spinal nerve dorsal horn - ~~> the POSTERIOR column of grey matter in the spinal cord (shape differs depending on spinal segment) - contains SENSORY neuron cell bodies ventral horn - ~~> the ANTERIOR column of grey matter in the spinal cord (shape differs depending on spinal segment) - contains MOTOR neuron cell bodies 3 types of primary somatosensory afferent axons - ~~> 1) Aβ 2) Aδ 3...

Merkell cells - ~~> - slowly adapting - 25% of mechanosensory afferents in hand - highest spatial resolution - edges, points, corners, curvature - static indentation ** Meissener - ~~> - rapidly adapting -40% of mechanosensory innervation in hand - skin motion, indentation, low frequency vibrations for textured objects*** - more than 4x more sensitive than Merkell to skin deformation, but larger receptive fields so less spatial resolution - ie. tea set plate etchin...
