Answer:
The correct answer is: Clostridium Tetani.
Explanation:
Clostridium tetani is a Gram-positive bacteria found in soil.
<u>C. tetani may grow and generate </u><u>tetanospasmin</u><u>, a powerful toxin that interferes with </u><u>motor neurons</u><u>, producing </u><u>tetanus</u><u>, if introduced into a </u><u>wound</u>.
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. <u>This blockage causes </u><u>extensive motor neuron activation and muscular spasming</u>. 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.
Answer:
There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.
Explanation:
Answer: reproductive, endocrine, and nervous systems
- Hormones provide feedback to the brain to affect neural processing. Reproductive hormones affect the development of the nervous system. The hypothalamus controls the pituitary gland and other endocrine glands.
