HUMAN DEVELOPMENT Flashcards
3 MAJOR PATHS OF HUMAN DEVELOPMENT
Physical Development, Physical Development, Cognitive Development
changes in bodily appearance and structure, and in bodily activities like motor skills
Physical Development
changes in social and emotional aspects of personality
Psychosocial Development
changes in the thought processes that could affect language, learning activities, and memory
Cognitive Development
a process whereby traits of parents are handed down to their offspring via the genes.
HEREDITY
the forces that affect man, like physical forces, natural forces, and social forces.
ENVIRONMENT
(a) thread-like or rope-like bodies that contain the genes, either classified as (b)
(a) Chromosomes (b) autosomes or trait chromosomes
bearers of hereditary traits.
Genes
are strong genes; the trait that dominant genes carry will be manifested in the offspring
Dominant genes
are weak genes; the traits can only be manifested if it is paired with another recessive gene of its kind.
Recessive genes
“Like begets like”, where human individuals will reproduce their own kind.
Principle of Reproduction
“No” 2 individuals of any kind are exactly “alike” even identical twins have mild differences.
Variation
similarities and differences among family members.
Dominance and Recessive
the hereditary endowments and the number of births and the millions of sperm which fertilize the ripened egg is played and attributed by chance alone.
Chance
sex-linked traits are carried by the same genes that determine sex which are carried by women but, usually suffered by most men (ex. Baldness, color blindness, hemophilia).
Sex-Linked Characteristics
the appearance in general like facial features, complexion, height, and body built.
Physical traits
are characteristics like harelip, cleft-plate, and stub-finger.
physical defects
are predisposition to tuberculosis, asthma, and hypertension.
physical diseases
examples are I.Q. level, some cases of mental retardation, and predisposition to mental disorder.
Mental traits
like artistic, literary, athletic, musical, and numerical talents.
Special talents/abilities
arise when one egg cell/ovum further divides into two after being fertilized by one sperm, have same sex and looks
Identical or monozygotic twins
arise from two eggs/ova which are fertilized by two different sperm cells, the same or different sexes
Fraternal or dizygotic twins
different area of the body, called an erogenous zone, at each of the five stages of development:
Oral, Anal, Phallic,Latency, Genital
Children develop ______ ,mental models, to interpret information
schemata
is when they take in information that fits with what they already know
Assimilation
describes when they change their schemata based on new information
Accommodation
From fertilization to 2 weeks
rapid cell division
Zygotic/Germinal Stage
2nd week to 8th weeks or 2 months
Umbilical cord connect the embryo to the placenta
Embryonic Stage
8th weeks to birth
Appearance of the first bone cells
Fetal Stage
substances that are damaging and causing birth defects.
Teratogens
fetus’ head emerges first through the birth canal followed by one shoulder then the other, next by the arms one at a time and finally the legs.
Natural or Spontaneous Birth
employed with the aid of surgical instruments if the fetus is too large or if its position does not allow normal birth process.
Instrument Birth
fetal buttocks appear first, followed by the legs, arms and eventually the head.
Breech Birth
the fetus lies crosswise in the mother’s uterus.
Transverse Presentation Birth
the fetus is delivered surgically by means of a slit created in the maternal abdominal wall.
Cessarian-Section Birth
(a) from birth to two weeks and is
subdivided into: (b)
(a) Infancy (b) Period of the Partunate
