The radiologic
skeletal survey is most useful tool for detecting occult trauma fractures in children
younger than 2 years old. A current policy states that skeletal survey is
mandatory in all cases of suspected child abuse because younger
children are easier to lift, shake, throw, pull and fall. Moreover, occult fractures can be detected by bone scan
though; bone scan is not specific for fracture but still most useful in
detecting occult rib fractures.
The term used to describe a harmless organism resembling a harmful one is batesian mimicry. Cryptic coloration or camouflage makes prey difficult to spot, while aposematic coloration is a type of coloration exhibited by animals with effective chemical defenses. Mullerian mimicry is a type of mimicry in which two or more unedible species resemble each other.
