What is "flaccid paralysis"

n. weakness or loss of muscle tone resulting from injury or disease of the nerves innervating the muscles

Flaccid paralysis is a clinical manifestation characterized by weakness or paralysis and reduced muscle tone without other obvious cause (e.g., trauma). This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles. For example, if the somatic nerves to a skeletal muscle are severed, then the muscle will exhibit flaccid paralysis. When muscles enter this state, they become limp and cannot contract. This condition can become fatal if it affects the respiratory muscles, posing the threat of suffocation.

Flaccid paralysis is a term used in tactical shooting when a headshot is taken and the bullet enters the cranial cavity in the "T-zone". T-zone shots are normally made in a situation where the suspect is armed and holding a hostage, usually at gun or knife point. The T-zone is roughly a T-shaped area from the outside of one eye socket to the outside of other eye socket and extending down the bridge of the nose to the upper lip. This area forms the "T" from which it derives its name. When the bullet enters the T-zone, it strikes the medulla oblongata causing flaccid paralysis. The advantage of flaccid paralysis is the subject is rendered incapacitated instantaneously preventing involuntary muscle contraction that may pull the trigger or cause other movements that may injure or kill the hostage. This is a difficult shot even by the best marksman and should only be attempted by trained personnel.
