If your just looking for a description here you go.

Explanation:

Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

Radda [10]

Answer:

The correct answer is: Clostridium Tetani.

Explanation:

Clostridium tetani is a Gram-positive bacteria found in soil.

C. tetani may grow and generate tetanospasmin, a powerful toxin that interferes with motor neurons, producing tetanus, if introduced into a wound.

Tetanospasmin travels throughout the body via the lymphatic and bloodstream, where it is taken up by different sections of the nervous system. Tetanospasmin inhibits the release of the inhibitory neurotransmitters glycine and gamma-aminobutyric acid at motor nerve terminals in the nervous system. This blockage causes extensive motor neuron activation and muscular spasming. These muscle spasms usually start at the top of the body and work their way down, starting about 8 days after infection with lockjaw and progressing to spasms of the stomach muscles and extremities. The muscle spasms last several weeks.

Tetanus toxoid vaccinations, which are often given to children around the world, can inhibit the toxin's activity.
