Spinal Cord
A part of the spinal cord that contains ascending and descending neurons and can send fast signals because of myelination.

The cervical plexus has only one terminal nerve associated with it.
What is the Phrenic Nerve?
This sensory receptor detects chemicals dissolved in boogers or spit, and is associated with Taste and Smell.

This is the process of making the lens more spherical to view close up objects.
What is Accommodation?
This term means that you have trouble seeing items close up. People with this problems are called "farsighted"
What is Hyperopia?
One of the smallest bones in the body, this ear bone is called the “Hammer” because it has a long handle and an expanded end.
What is the Malleus?
Bonus 100 points for each, what are the other two bones called?
A network of interweaving anterior rami of the spinal nerves. They create redundancy so if individual nerves are damaged others can possibly pick up the slack.
What is a Nerve Plexus?
The femoral nerve and obturator nerve are part of this plexus located in the lower back.
What is the Lumbar Plexus?
If something moves these receptors catch it, they detect pressure, vibration, and stretch. They deal with hearing and equilibrium
What are Mechanoreceptors?
These cells provide vision in bright light, they are activated by high intensity light and provide color recognition and visual sharpness.
What are Cone Cells?
An inherited genetic trait this disorder is characterized by the absence or deficit in one type of cone cell.

This part of the ear is air filled and contains the tympanic cavity and auditory tube.
What is the Middle Ear?
A bundle of nerve bodies or somas that are housed outside of the CNS usually in a posterior root.
What is a Ganglion?
These two terminal nerves make up the nerve that is usually referred to as the Sciatic nerve and if pinched it causes shooting pain in the legs.
What are the Tibial Nerve and Common Fibular Nerve ?
Hot peppers trigger these receptors. “Like Ouch these ghost peppers hurt my tongue!”
What are Nociceptors?
Movement of the eyes for near focus.
What is Convergence?
Nearsighted people have trouble seeing things that are far away and they suffer from this ocular disorder.
What is Myopia?
Static equilibrium, linear acceleration, movement of the otoliths, and head position while standing are all detected by the Maculae of this apparatus.
What is Vestibular?
A type of neuron that is located between sensory and motor neurons. They make up the majority of neurons in the body and play a crucial role in integrating sensory information and regulating motor activity.
What is an interneuron?
The Phrenic nerve innervates this muscle in the abdomen that helps with breathing.
What is the Diaphragm?
These receptors are found in the retina of the eye, they can detect changes in light intensity, color, and movement.
What are Photoreceptors?
This structure is located in the back of the eye on the retina, it has the area of highest resolution, and therefore contains the highest number of Cones.
What is the Fovea Centralis?
This occurs when there are one or more unequal curvatures of the cornea.
What is an Astigmatism?
Detection of these are done by Vibrations of the wide distal end of the basilar membrane.
What are Low Pitched Sounds?
When neurons cross over from one side of the spinal cord to the other.
What is Decussation?
This plexus is the largest plexus in the body and has 5 terminal nerves associated with it.
What is the Brachial Plexus?
These receptors are located mainly in the skin and hypothalamus, they detect changes in temperature.
What are Thermoreceptors?
These cells allow you to see in black and white, they are longer and narrow, they are really helpful in low light or unlit rooms.
What are Rod Cells?
Also known as “Old Man Eye” it means you have trouble reading words close up.
What is Presbyopia?
The inner ear is a fluid filled bony labyrinth and contains these three structures.
What are the Cochlea, Vestibule, and Semicircular Canals?
This kind of reflex is when the receptor and effector organs are on different sides of the spinal cord.

_____Cornea
_____Aqueous Humor
_____Lens
_____Vitreous Humor
Each eye sees slightly different spatial information and transmits these differences to the brain. The brain then uses the discrepancies between the two eyes to judge distance and depth. This type of vision allows depth perception.
