Tetanus

For my project, I chose tetanus because when I was eleven, I got my tetanus shot. At the time, I didn’t know what tetanus was so my dad explained it to me. I thought the topic was interesting. At the time, I thought that tetanus was only caused by rust getting on an open wound or cutting yourself with something rusty. I only knew that it stiffened your face muscles and could kill you.

Tetanus, also known as lockjaw, is caused by the bacteria Clostridium tetani. The bacteria thrives in places like dirt, dust, mature, and sometimes in the intestines of people and animals. That means if you
The human beings' nervous system consists of the brain, spinal cord, and the nerves. The nervous system enables a way for the brain to receive information about someone's surrounding. Then, the brain is able to send signals to various areas of the body, so it can respond. Millions and millions of cells called neurons creates the nervous system. “Specialized neurons called receptors are located in the ears and eyes and the other sense organs of the body. The receptors translate events in a person's surroundings . . . into nerve messages, which are known as impulses. Nerve impulses travel along nerve fibers at speeds of 3 to 300 feet (0.9 to 90 meters) per second” (Stevens). There are receptor cells in the eyes that respond to light rays that reflect off of things and translate them into nerve patterns. Sensory neurons carry the information from the receptors to the association neurons in the brain and spinal cord. When the brain receives the message, it analyzes it and decides what the body should do. Neurons called motor neurons, which carry messages from the brain to the muscles and other parts of the body, make it able for the impulses through. The body receives the instructions and responds. Even though it only takes a few seconds to happen, it’s a complicated
