Answer:
oropharynx
Explanation:
The pharynx, which is sometimes referred to as the throat, is the cone-shaped muscular tube that links the oral and nasal cavity to the larynx and oesophagus. The pharynx, which serves as a passage for movement of food from the mouth to the esophagus and also as an airway, is divided into three parts, namely: the nasopharynx, oropharynx, and laryngopharynx.
The oropharynx is the part that receives both air and food. It is the middle part of the pharynx (throat) found at the back of the soft palate of the mouth and also underneath the nasopharynx.

Answer:
Muscles are stimulated by electricity. The effect depends on the intensity of the current and the type of muscle it travels through.
The victim may be unable to let go of the source of the current, making the duration of the contact longer and increasing the severity of the shock.
When a current above 10 mA travels through extensor muscles, it causes a violent spasm. If the muscles affected are the hip extensors that lengthen the limbs away from the body, the victim may be propelled, sometimes many metres away!
Muscles, ligaments and tendons may tear as a result of the sudden contraction caused by an electric shock. Tissue can also be burned if the shock is lasting or the current is high.planation:
