Concept Statements
• The process of Human Growth and Development is divided into many stages, both during Pre-natal and Post-natal periods.
• The stages of human growth and development are marked with specific incidents and are helpful in assigning age verification by the forensic experts.
• Understanding criteria of assigning stages of development is important for forensic experts.
CONTENTS DEALT IN THIS LESSON
• MAJOR STAGES OF GROWTH AND DEVELOPMENT BOTH DURING PRE-NATAL AND POST-NATAL PERIODS OF HUMAN GROWTH & DEVELOPMENT.
OBJECTIVES
The learner should be able to• Enlist major stages of human growth and
development.• Enlist & describe duration of stages of Pre-
natal Growth & Development.• Enlist & describe duration of the major stages
of post-natal development.
MAJOR STAGES OF G & D
The process of human growth and development is divided in two main stages:-
• 1. PRE-NATAL STAGE - ( Conception To Birth).
• 2. POST-NATAL STAGE – (Birth to Adulthood).
GROWTH & DEVELOPMENT
PRENATAL STAGES• 1.GERMINAL
• 2. EMBRYONIC
• 3.FETAL
POSTNATAL STAGES• 1.BABY
• 2.CHILD
• 3.ADOLESCENCE/ PUBERTY
• 4.ADULTHOOD
PRE-NATAL STAGES
Pre-natal period is further divided into three major stages :-
• 1. Germinal Stage -It’s duration is 2 weeks.• 2. Embryonic Stage, -It’s duration is 6 weeks• 3. Fetal stage -it’s duration is 30 weeks.
PRIMARY HUMAN FEMALE REPRODUCTIVE ORGANS
PRE NATAL STAGES OF G & DTHIS ILLUSTRATION CLEARLY DEMONSTRATES THAT THE FORENSIC EXPERT
MAY EASILY ASSIGN AGE BASED ON THE DEVELOPMENT STAGE OF THE EMBRYO (FROM ITS RELATIVE SIZE AND VISIBILITY OF ANATOMICAL PARTS.
BRIEF DESCRIPTION OF PRE-NATAL STAGES
• 1. Germinal Stage:- The germinal stage starts with the fertilization of female ovum with a sperm of the male.
Fertilization occurs typically two weeks after the first day of last menstruation cycle of the pregnant woman.
• 2.Embryonic Stage :- This stage starts with the COMPLETION OF implantation of the blastocyst on the wall of the uterus (WOMB).
• 3. Fetal Stage :- After 8 weeks of growth and development after fertilization , the developmental stage is known as fetal stage, and the embryo converts to the Fetus who has all the anatomical organs in much better state as compared to those of the embryo (as seen in Figure in the previous slide).
• The duration of fetal stage lasts about 30 weeks, till delivery where after, the neonate starts to grow out side the safe environment of the mother.
POSTNATAL GROWTH & DEVELOPMENTAL STAGES
• 1.BABY, UPTO 3 YR.• A) NEONATAL, up to 1 month.• B)INFANT, up to 1 year.• C)TODDLER, up to 18 month- <3 YR.• 2.CHILD, 3 Yr. to Adolescence/Puberty.• A)Early childhood,<5year.• B)Pre-adolescent childhood. 3.ADOLESCENT/PUBERTY/Late childhood.• 4. ADULTHOOD- Young Adult, up to 35,• Middle Aged Adult, up to 50• Old , up to 65 • Very old, >65 until death.

APGAR SCALE (Backronym of G & D )
• The Apgar scale is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. The five criteria are summarized using words chosen to form a backronym (Appearance, Pulse, Grimace, Activity, Respiration).
