Normal Human Development Flashcards
What is growth?
Quantitative changes in size, dimension, or structure–quantitative (it can be measured) (e.g., height, weight, head circumference)
How do we measure head circumference?
Tape measurement (globella or most prortuded part of forehead, and then it should cross across the occipital protuberance and then goes back to the golbella)
Hanggang kelan ba lumalaki ang head circumference?
20-21 years old
What is development?
Quantitative and qualitative changes that occure throughout life. These are refinement of skills.
What is adaptation?
These are changes in response to the environment or situation demands
Why do we need to adapt?
For survival (e.g., skin color, antibody formation)
What is assimilation?
Assimilation is application of past information to new information (e.g., using concepts learned from undergrad → boards review)
What is accommodation?
Accommodation is alteration of past information in light of new information (e.g., eat a watermelon seed)
What is fetal age?
Age of fetus
There are two ways to get the fetal age, what are they?
Gestational age
Conceptional age
What is gestational age?
Also known as age of gestation (AOG), measured from the first after the last menstruation.
This is the most common indicator of fetal age
This is the most common indicator of fetal age. What is this called?
Gestational age
What are the terms used in gestational age? Their week counts?
Normal term (38 - 42 weeks)
Pre-term < 38 weeks
Post-term > 42 weeks
What is conceptional age?
Age of conception/AOC
Measured from the last sexual intercourse
Considered as the most accurate
What is chronologic age?
Age counted from birth
What is the adjusted age?
Used to assess which milestones are expected of a preterm infant
How do we compute the adjusted age?
Chronological age in months - 40 weeks - AOG (age of gestation) / 4 weeks
Chronological age (weeks - (40 weeks - AOG)
You have a 9-month old px born at the 25th week of gestation
9 months - (40 weeks - 24 weeks/4 weeks)
9 months - (16 weeks/4 weeks)
9 months - 4 months
5 months
What is ovulation? It is triggered by?
- It is the formation of one or more egg cell
- Triggers by luteinizing hormone
What is ovum?
Product of a 28-day ovarian cycle (ovum is synonymous to egg cell)
What is fertilization?
- Chromosomal union of the sperm cell and egg cell (the egg cell and sperm cell unite, haploid cells)
What is zygote? When is it called zygote?
Fertilized egg cell
We call it zygote from fertilization → implantation
What is morula?
It is spherical ball of cell undergoing rapid mitosis
What is blastocyst?
Advanced form of morula capable of implantation (implanted at the uterus)
What is an embryo?
From implantation → to 5-8 weeks (2 months)
What is a fetus?
5-8 weeks (2 months) → term
What is gastrula?
Formation of primary germinal layers (precursor of the primary germinal layers)
What is conceptus?
Developing placenta and embryo
What is the correct cycle of embryonic development?
Ovulation → ovum → fertilization → zygote → morula → blastocyst → embryo → fetus → gastrula → conceptus
What are the 3 primary germinal layers?
Ectoderm, mesoderm, endoderm
The process of forming the gastrula is called __________.
Gastrulation
What is ectoderm? It is a precursor to?
Outermost layer
Precursor to the integumentary system and nervous system
What is the mesoderm? It is a precursor to?
Middle layer
Precursor to:
- renal system,
- musculoskeletal system,
- cardiovascular system, and
- reproductive system
What is endoderm? Precursor to?
It is the innermost layer.
Precursor to: endocrine, digestive, and respiratory
What is Piaget’s Cognitive Development?
- Child is actively responsible for development
- Child is explorative and curious
- Child learns from 5 senses
Give an example for Piaget’s Cognitive Development
A child learns that something is hot by touching it. So, the child will no longer touch it.
What are the four stages of Piaget’s Cognitive Development?
Sensorimotor, Preoperational, Concrete Operational, and Formal Operational
Immature reflexes, circular reaction (cause and effect reaction). What stage is this in Piaget’s and what is the expected age for this stage.
Sensorimotor Stage. Birth to 2 years old
Symbolic language, active play, egocentricity. What age is this expected and what stage is this in Piaget’s Cognitive Development?
2 years old. Preoperational Stage
This is when the child is able to do logical thinking, conservation, inductive reasoning (something specific but you are able to generalize it e.g., you have a brown cat with four legs named Brownie and then you see a dog that is brown and has 4 legs and you say that the dog looks like brownie.) What age is this expected and what stage of Piaget’s Cognitive Development?
Concrete Operational Stage, 7 years old
This is when you are able to do abstract thinking, problem solving, deductive reasoning. What stage is this in Piaget’s Cognitive Development? What age is this expected?
Formal operational stage; 11 years old
He was the one who developed the psychosexual development, wherein the development of cognition is dependent on internal pleasure.
Sigmund Freud
This stage is when the child puts things in mouth. What age is this expected?
Oral stage: 0-18 months
What are the two categories under the oral stage?
Oral incorporative and oral aggressive
What is oral incorporative?
Subo ng subo, gullible, excessive eating/drinking, unusual optimism
