Precision of eye movement is due to the fact that extrinsic eye muscle motor units typically innervate 8 to 12 muscle cells and in some cases as few as 2 or 3 muscle cells. precision of eye movement is due to the fact that extrinsic eye muscle motor units typically innervate 8 to 12 muscle cells and in some cases as few as 2 or 3 muscle cells. true false

True

Explanation:

The answer is TRUE.

Motors unit is the basis of muscle movement and contraction. The eye muscle motor units are a group of muscle fibers and nerve fibers that helps to contract of the eye. The number of muscle fibers used for contraction may change and it determines the efficiency of the movement.

Therefore the accuracy or the precision of the eye movement depends upon the number of muscle cells and it may be sometime 8 to 12  and sometimes as few as  2 or 3 muscle cells.

Thus the answer is  TRUE.

local max is .5

step-by-step explanation:

the local maximum is for x values between 2 and 4

it looks like the x value is 2.5 and the y value is .5

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
