D) I think there was something about “far away objects are focused ... on the retina and near objects are focused ... on the retina?

E) Far point can be 1m away​

A) Depends on the state of rods

B) Means the distance of ... and 1 arc

C) Depends on the visual field

D) Can be impaired by defects of focusing

A) They maintain activity of Ia afferent

B) They detect the length of extrafusal muscle fibres

C) They produce contraction of nuclear bag and chain fibres

D) They stimulate the activity of Ib fibres

A) Elicited by postganglionic neurons

D) Appears over occipital lobes when eyes are closed

E) Measured mostly on frontal lobe for conscious thought

A) Contraction of smooth muscles of vessel by alpha 1-Adrenergic receptor

B) Decrease dilation of bronchi by beta 2-adrenergic receptor

C) Increased liberation of epinephrine mediated by alpha1

D) Decrease contraction of gastric sphincter by beta 1-adrenergic receptor

A) Nicotinic receptor generates action potential on motor neuron end plate

A) Degeneration of rhodopsin

B) Regeneration of light sensitive of rhodopsin

C) Constriction of pupil

D) Dilation of pupil

E) Increased sensitivity of retina for light
