Which structures in the Vestibular System detect Angular Acceleration (Head Rotation)?

1

Which structures in the Vestibular System detect Linear Acceleration (Head Tilt)?

You suspect your patient has a lesion along the sympathetic pathway to the eye, possibly relating to Horner's Syndrome. To determine where exactly the lesion is located you put eye drops in their eyes and test for sweating. The eyes dilate and you note a lack of sweat, where is the lesion?

1

Select the characteristic symptoms of Horner's Syndrome.

1

Generally speaking, Horner's Syndrome is caused by a disruption to the parasympathetic pathways to the eye and face.

1

Which of the following are true regarding Lock-In Syndrome?

1

This is ( Decerebrate, Decorticate, Decerebellate ) Posturing indicative of a lesion ( at or above the midbrain, in the lower brainstem, in the cerebellum ).

This is ( Decorticate, Decerebrate, Decerebellate ) Posturing indicative of a lesion ( in the lower brainstem, at or above the midbrain, in the cerebellum ).

1

How are Horner's Syndrome and Wallenberg's Syndrome related?

1

Symptoms for ( Wallenberg's, Horner's ) Syndrome include:
( Ipsilateral, Contralteral ) ( Decreased, Increased ) Facial Pain and Temperature Sense.
( Contralateral, Ipsilateral ) ( Decreased, Increased ) Body Pain and Temperature Sense.

Wallenberg's Syndrome may be caused by Thrombosis in the ( Vertebral a., Basilar a., Anterior Spinal a., Posterior Spinal a. ) or ( PICA, AICA, PCA, SCA, ACA, MCA ).
