The Nervous and Reproductive System

William Wright

The Nervous System

The Nervous System is a complex net of wiring that sends signals to different parts of the body.

The Central Nervous system has the brain, spinal cords, and nerves. This acts as mission control and does all of the sending.

The Peripheral Nervous system has sensory neurons, ganglia, and nerves connecting to the Central Nervous system. This receives sent signals and acts them out.

Each hemisphere of the brain has three parts; the cerebral cortex (gray matter), internal cerebral (white matter), and the basal nuclei.

The Diencephalon holds the thalamus, hypothalamus, and epithalamus.

The Brain Stem has three separate parts too. The midbrain; the sensory thing for eyes and ears. Pons; just conducting lines. And the medulla oblongata; controls breathing.
Epilepsy is the weird electrical shoot outs that cause seizures. It stiffens the body, keeps eyes open, stops your breathing, and makes people have a loss of urine. Treatment would be drugs like Vimpat and Lyrica.

Alzheimers Disease weakens memory. It tends to effect older people and minds. It is not common.

Reproductive System

The Reproductive System allows the human race to populate the earth we live on.

Spermatogenesis is when sperm is created. 1 diploid cell is turned into 4 haploid cells be they can mature.

Oogenesis is almost the same as Spermatogenesis but as the four haploid cells are created, only one becomes and ovum. It just so happens that they are different.
HPV is the most common STD in america. It causes genital warts and cancers. There are vaccines to cure it.

Pelvic Inflammatory Disease is a disease 1 out of 8 women get. It can be caused by ghonorrhea and chlamydia. It can cause pain and pregnancy issues.
