1) Narcolepsy:
1- Sleep disorder that causes excessive sleepiness and daytime sleep attacks
2- victims can fall asleep in mid sentence or laughter.
3-Occurs in people mostly ranged from age 15 to 30
2) Bells Palsy:
1- disorder of the nerve that controls movement of the muscles in the face.
2- Can result from stroke, or dead nerve cells.
3- Usually it is almost impossible for the face to contract back to normal, and most victims face does not return to normal.
3) Serotonin:
1- can affect the functioning of our cardiovascular system, muscles, and various elements in the endocrine system.
2- decreases sexual desire
3- imbalance in serotonin levels may influence moods in a way that leads to depression.
4) Dopamine:
1- similar to adrenaline, causes you to become hyper.
2- affects the brain processes that control movement, emotional response, and the capacity to feel pleasure and pain.
3- A shortage of dopamine can cause a person to lose the ability to think rationally.
5) Dementia:
1- affects memory, thinking, language, judgment, and behavior.
2- develops when the parts of the brain that are involved with learning, memory, decision-making, and language are affected by one or more of a variety of infections or diseases.
3- Alzheimers disease is a form of dementia.

1) Function of the medulla is it controls involuntary actions as the heart beat, breathing, and blood pressure.
2)Function of the cerebellum is it helps in basic coordination of motor movements as well as basic facets of memory and learning.
3)Function of the olfactory bulb is it relays sensory signals to the olfactory tract and helps with sense of smell.
4)Function of the optic chiasm is it allows the information from both eyes to be processed together.
5) Function of the corpus collosum is it connects the left and right side of brain helping in eye movement, maintaining the balance of arousal and attention, and tactile localization.

Transcription:
1. DNA polymerease seperates DNA at promoter point.
2. Nucleotieds attach to the DNA to form an RNA strand.
3. DNA polymerease detaches from the DNA strand.
4. RNA leaves the DNA and the DNA closes.

Translation:
1. RNA Enters the Cytoplasm.
2. RNA Attaches to a ribosome.
3. mRNA Brings amenio acids to the ribosome.
4. Codons and Anti-Codons bind.
5. Ribsome Produces a Protien Strand.

1. regulates vital functions
2. coordination of body
3. sends messages about smells to rest of brain
4. crosses information from eyes to rest of brain
5. binds to hemispheres of brain and facilitates communication between them.

Epilepsy -1
1.Might be because of brain injury, stroke, tumor, poisoning, or lack of oxygen.
2. partial seizures start in one part of the brain, while generalized seizures happen all over it.
3. triggers include lack of sleep, lights, overstimulation, fever, etc.
Nervous system stimulants -2
1. high potential for addiction
2. cocaine & meth increase dopamine to stimulate brain
3. everything seems more intense to the user.
ALS -3
1. Lou Garig’s disease
2. makes efferent neurons degenerate
3. No cure, but symptoms can be treated
Wilson’s disease -4
1. to much copper
2. can cause swelling
3. can cause jaundis
Alzheimers -5
1.dementia usually is caused by it
2. affects hippocampus and short term memory first
3. causes beta-amyloid plaques and neurofibrillary tangles

Transcription is when DNA is transcribed by an enzyme called RNA polymerase. RNA polymerase attaches to the DNA at the promoter region.The DNA strand opens up and allows the RNA polymerase to a single strand of DNA into a single strand of RNA polymer called messenger RNA. When RNA polymerase transcribes the DNA, guanine pairs with cytosine and adenine pairs with uricil. Then the mRNA detaches from the DNA.

1. DNA transcription is the process that invovles the transcring of the genetic information of DNA.
2. ?
3. The RNA enzymes are essential to life that are found in all to offer a protective chaperone funtion.
4. Two types were soon discover DNA and RNA ribonucleic acid strains produced smooth colonies.

1. Peripheral Neuropathy- diabetes is the most common cause, pressure can damage the nerves, and can cause problems with organs.
2. Wilson’s Syndrome- a geneti disorder, caused by too much copper in tissues, it causes clumsiness, depression, and can lead to Parkinson’s syndrome.
3. Parkinson’s Disease- from the death of dopamine producing cells, brain cant properly send messages, results in tremors and difficulties walking.
4. Narcolepsy- causes random sleep patters and sever drowsiness, may be an autonomic disease, there is no definite cause.
5. Bipolarism- moods reffered to as mania, people have one depressed mood with bipolarism, and there is no known cause.

1. The function of the medulla is to control the autonomic functions in the body.
2. The function of the cerebellum is to control motor functions and is thought to also control some cognitive functions.
3. The olfactory bulb is involved with the sense of smell.
4. The function of the optic chiasm is the part of the brain where the two optic nerves cross which allows you to see.
5. The function of the corpus collossum is to connect the two hemispheres of the brain and allow them to communicate together.
