Q

Gyri, sulci and fissures.

A

In the cerebrum. Gyri are raised ridges, sulci are deep clefts between the ridges and fissures are even deeper clefts between major divisions of the cerebrum.

61
Test for visual accuity.
Standing 20 feet from the chart read the smallest line that you can. 20/20 vision means the person can read the line they should be able to read at 20 feet.
62
Test for astigmatism
Stand 20 feet from astigmatism chart. Cover one eye and observe if any lines or planes are darker.
63
Binocular Vision
Brain focusing images from two separate eyes. Demonstrated if you hold arm out and point at distant object. May see two fingers, may be different in distinctiveness and may change if you close an eye.
64
Tests for color blindness
Affects only males. May only see shades of gray or may lose ability to see red and green only.
65
Blind Spot
Each eye has a blind spot where the optic nerve exits the eye. Demonstrated by covering eye and looking at X on the board while walking toward board you find a spot where the mouse disappears.
66
Air Conduction and Bone conduction test.
sensory deafness: hair cells of cochlea are damaged. Conduction deafness: sound cannot normally conduct through middle ear. Used tuning fork to compare.
67
Nystagmus
Reflexes that aim the eye. Tested by spinning someone in a chair with head 30 degrees forward so that the horizontal semicircular canals are horizantal to the floor. Occurs in the direction of the fast movement.
68
Past-Pointing
Show the effect of vestibular reflexes on postural muscles. Had subject close eyes and point to tip of someones finger then spun them and had them try to touch tip of finger. Arm strays in the direction they were spinning.
