Cranial Nerves
Created in 1862, this assessment remains the most widely used tool for evaluating visual acuity.
What is a Snellen chart?
The peripheral nervous system contains this many pairs of spinal nerves.
What is 31?
Shoulder abduction corresponds to this myotome.
What is C5?
Pain and temperature are examples of this sensation category.
What are superficial sensations?
A tuning fork assesses this deep sensation.
What is vibration (pallesthesia)?
This cranial nerve innervates the levator palpebrae muscle.
What is CN III (Oculomotor)?
This system is best known as “fight or flight.”
What is the sympathetic nervous system?
The umbilicus lives in this dermatome.
What is T10?
These sensations require higher-level processing of sensory information.
What are cortical sensations?
An aesthesiometer is used to assess which sensation?
What is two-point discrimination?
This nerve helps you chew your favorite snack with its motor branch.
What is CN V3 (Mandibular branch of Trigeminal)?
These roots carry sensory information into the spinal cord.
What are dorsal roots?
This dermatome is on the lateral (radial) side of the antecubital fossa, just proximal to the elbow.
What is C5?
The inability to recognize an object by touch alone is known as this.
What is astereognosis?
What is agraphesthesia?
This nerve allows you to shrug your shoulders.
What is CN XI (Accessory)?
The brachial plexus typically originates from these spinal levels.
What are C5–T1?
Elbow flexion corresponds to this myotome.
What is C6?
This sensation may be carried by both the DCML and spinothalamic pathways.
What is light touch?
A patient who cannot abduct the shoulder may have a lesion of this nerve.
What is the axillary nerve?
This nerve is tested when you ask a patient to “smile, show teeth, puff your cheeks.”
What is CN VII (Facial)?
There are this many branches in the brachial plexus.
What is 5?
This dermatome is located over the acromioclavicular joint.
What is C4?
Proprioception and vibration are part of this sensation category.
What are deep sensations?
This test is used to assess double simultaneous stimulation.
