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 , the neurons involved in muscle contraction are affected.

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.
