Question

Toxin produced by tetanus affects
A. Voluntary muscles
B. Involuntary muscles
C. Both voluntary and involuntary
D. Jaw bones

Answer 1

Hint: Tetanus is a dangerous nervous system infection caused by a toxin-producing bacteria. Muscle spasms, particularly in the jaw and neck, are a symptom of the condition. Lockjaw is a frequent name for tetanus. Tetanus consequences that are severe can be fatal.

Complete solution :-
Tetanus toxin is an exceptionally strong neurotoxin generated by Clostridium tetani's vegetative cell in anaerobic circumstances, which causes tetanus. Clostridia have no known purpose in the soil environment, where they are most commonly found. It's also known as TeNT, or spasmogenic toxin.

The most appropriate answer is option A. Voluntary muscles.

Muscles that are not voluntarily used-
Tetanus, often known as lockjaw, is a bacterial infection caused by the bacterium Clostridium tetani, which can be found in soil, saliva, dust, or manure. The germs usually enter through a break in the skin, such as a cut or puncture wound, from the soil. They produce toxins that cause muscle spasms by interfering with normal muscle contractions, i.e. it affects voluntary muscles. As a result, the right response is 'voluntary muscles.'

Without treatment, a tetanus infection can be fatal. According to the Centers for Disease Control and Prevention (CDC), about 10 to 20% of tetanus infections are deadly. Tetanus is a medical emergency that necessitates rapid hospitalisation.

Note:-
Your doctor may recommend a booster if the wounded individual hasn't received a tetanus shot in the last five years and the wound is deep or unclean. The booster shot should be given to the affected person within 48 hours after the injury. Tetanus is not caused by rust, although it can be caused by stepping on a nail if you are not inoculated. Tetanus-causing bacteria can enter the body through any type of skin trauma, including burns and blisters. Tetanus is no longer as widespread as it previously was.
