100
Focuses the image on the retina
What is the lens
100
These structures carry information out of the retina
What is the ganglion cells
100
Important structure of the brain for reaching out and grasping the object not maintaining the grasp
What is the cerebellum
100
Muscle spindles are found here
What is in the extrafusal muscle fibers
100
This type of reflex has one synapse and is very quick
What is a monosynaptic reflex
200
Muscle that constricts the pupil and is controlled by the parasympathetic nervous system
What is the circular muscle
200
Type of ganglion cell that is color insensitive and rapidly adapting
What is M ganglion cells
200
Pathway responsible for object recognition
What is the Inferior temporal or ventral "what" pathway
200
Prevents muscles from tearing when tension is too great
What is the golgi tendon organ
200
A muscle's resistance to passive stretch
What is muscle tone
300
Extra ocular muscle that is controlled by cranial nerve III and functions to elevate the eyes
What is the superior rectus
300
Cells that are located between photoreceptors and bipolar cells
What are horizontal cells
300
A lesion in this brain area causes optic ataxia
What is the posterior parietal cortex
300
Cell bodies for groups 1a and II afferent neurons from muscle spindles are found here
What is the dorsal root ganglion
300
Ability to maintain appropriate relationship between body segments and between the body and environment for a task
What is postural orientation
400
Muscle in the eye that when weakened causes esotropia

Neuron that quickly sends information regarding any changes in muscle length
What are 1a afferents
400
Maintaining the body's center of mass within boundaries of space
What is postural stability
500
Muscles of the eyes that allow you to look up and right
What is superior rectus in the right eye and inferior oblique in the left eye
500
The inability to recognize faces
What is prosopagnosia
500
Object moving from finger surface to the palm of the hand and back
What is translation
500
these neurons give motor input to muscle spindles allowing them to stay taut and responsive at all times
What are gamma motor neurons
500
Ongoing postural adjustments while engaged in stationary tasks
What is steadying balance
