the growth of baby to an adult blank changes
Answers
Answer:
The infant and child differ structurally from the adult in a number of ways which are critical to the design for protection against impact forces and for adequate occupant restraint systems. The purpose of this paper is to bring together a profile of the anatomy, anthropometry, growth and development of the infant and child. Age differences related to the proper design of child restraint systems are emphasized. Problems discussed include child--adult structural differences, center of gravity of the body, the head mass in relation to the neck and general body proportions, positions of key organs, and biomechanical properties of tissues.
Introduction
Infants and children are not miniature adults. Body size proportions, muscle bone and ligamentrus strengths are different and thus occupant packaging for crash protection need special consideration. This paper is an overview of pediatric size and proportional differences with considerations of some child injuries in car crashes along with a review of some biomechanical data.
GROWTH OF THE INFANT BODY AS A WHOLE
Growth and development of the human body occurs continuously from birth through senesence (old age). Such development is sporadic and non-uniform, yet it does not occur haphazardly. For the most part, incremental growth of any dimension or part of the body occurs according to predictable trends. Most body dimensions follow trends which involve rapid growth separated by a period of relatively slower or uniform growth
