Answer:
somatic motor neuron hyperexcitability; inhibition
The neuronal circuitry to skeletal muscles involves neurons that stimulate contractions and those that inhibit contractions. The muscle spindles and Golgi tendon organs are involved in maintaining the proper muscle tonus (resting muscle tension); they work by signaling the CNS. Since tetanus involves SOMATIC MOTOR NEURON HYPEREXCITABILITY, the neurons involved in muscle contraction INHIBITION are affected.
Explanation:
Tetanus is a infection that is caused by a bacteria called Clostridium tetani. It occurs when open wounds in the body are not properly treated and they get infected. This wound can be caused by stepping on a nail or sharp object like broken bottle.
When tetanus enters an open wound present on the body, it attacks the neurons in the body, specifically the somatic motor neurons. Tetanus hinders the release of neurotransmitters and blocks the inhibitory properties of the muscles. These causes the muscles of the body to contract unhindered and uncontrollably resulting in spasms. This can also be referred to as neuronal hyperexcitabilty.
<span>The synthetic estrogen-like hormone is classified as a xenohormone. Xenohormones have hormone like affects when absorbed or ingested by animals. As a result, they cause a variety endocrine complications. These types of compounds in the environment can easily find their way into the fishes that humans consume and eventually cause endocrine problems in the human population.</span>
A species that is habitat specialist and lives at the highest elevation.
Explanation:
An ecosystem consist of plants, animals as well as micro-organisms but due to climate change the plants as well as animals are in danger . The case that has been provided in the question where due to climate change the temperature rises as a result the species living at the highest elevation are in problem .
Due to rise in temperature the snow is melting and the sea water level is rising. The animals and plants adapt themselves according to the climate where they are residing but suddenly if climatic change take place they will be unable to survive.
The animals which are mostly affected due to climatic change are snow leopard, polar bear, giant panda.
