Term
Which part of the eye has the sharpest image?

Term
What is the job of bipolar neurons and why are they named that?
Definition
It recieves impulses from photoreceptors and stimulates ganglion. It's named bi polar because it has two extenions, one side attaches to an axon and one side to a dendrite
Term
Ganglion cells receive impulses from bipolar neurons. What happens?
Definition
The axons of ganglion cells leave the retina in a tight bundle of fibers known as the optic nerve. The exit of optic never sends message to occipital love of cerebrum
Term
When the optic nerves cross what do they make? What does that eventually form?
Definition
The x is the optic chiasma and they eventually form the optic tracts
Term
The optic tract fibers synapse with what?
Definition
The lateral geniculate nucleus of the thalmus
Term
In the optical love of the cerebrum the optic tracts synapse with the what?
Definition
with the cortical cells and visual interpretation occurs
Term
What is the job and location of the pinna?
Definition
It's in the outter ear and picks up sound waves
Term
What is the job and location of the External auditory canal?
Definition
It's in the outter ear and directs sound waves to the middle ear
