  • ARE YOU OKAY?? That looked like it hurt!
  • OW! What's happening to me?!
  • "The nervous system normally controls automatic body processes, like the blood pressure, breathing rate, and heart rate of a human being. The two parts of the nervous system are the somatic and autonomic. The autonomic system regulates certain body processes and the somatic system is made up of the nerves that connect the spine and brain with muscles and receptors. It's kind of like your body's “electrical wiring”, according to"

  • One warm day,  Andrea and Andy were at the beach. Suddenly, Andrea felt a burning, stinging, prickling pain.  She ran out of the water screaming. A jellyfish had stung her, and she didn't know how to respond. She didn't even know what was happening! A man appeared. He said...
  • So, are you experiencing any symptoms such as..
  • well yeah
  • Stomach pain? Nausea? A headache? Muscle pain? Drowsiness? Difficulty breathing? 
  • Thank you so much for your help doctor!
  • Well, when a jellyfish stings you, the microscopic barbed stingers in their tentacles are released. A tube of venom penetrates the skin and may enter the bloodstream. The stingers are called 'cnidocytes' and the venom tubes inside are called 'nematocysts'. A protein called porin is found in the venom of jellyfish and other cnidarians (like sea anemones and corals). However, this neurotoxin is poisonous and affects the nervous system greatly. 
  • The symptoms that Andrea explained were all related to the nervous system. The nervous system "detects environmental changes that impact the body, [and] then works in tandem with the endocrine system to respond to such events", according to
  • Red, brown, or purplish stains that look like jellyfosh tentacles? Itching? Swelling? Throbbing?
  • If you're feeling any of these symptoms, get medical help immediately.  Symptoms such as trouble breathing, muscular spasms, or an irregular heart rate can lead to other system failures, like cardiac or muscular. Also, the hypothalamus is the link between the endocrine and the nervous system, which produces releasing or inhibiting hormones, controlling the production of other hormones. It also regulates other body parts.
