KNES 355 - Post-Natal Growth Lecture Notes

This set of flashcards focuses on key vocabulary terms and their definitions related to post-natal and prenatal growth concepts, as discussed in the lecture notes for KNES 355.

Post-Natal Growth

The period of growth occurring after birth, which involves changes in height, weight, and body composition.

Velocity Curve

A graph that shows the rate of change in growth (e.g., height) over time, indicating periods of acceleration and deceleration.

Take-off (TO)

The initial phase of a growth spurt when an individual’s growth rate begins to increase significantly.

Peak Height Velocity (PHV)

The maximum rate of growth in height that occurs during puberty.

Distance Growth Curve

A graph depicting the cumulative growth measures (e.g., height) at each age over time.

Cumulative Growth

The total amount of growth accumulated over a specific period.

Stature

The height of an individual, commonly measured in centimeters.

Body Mass

The weight of an individual, influenced by various factors including genetics and environmental conditions.

Growth Spurt

A rapid period of growth, usually occurring during childhood and adolescence.

Sex Differences in Growth

Variations in growth patterns and sizes between males and females, often influenced by hormonal factors.

Age at Peak Height Velocity (APHV)

The chronological age when an individual reaches their maximum growth velocity in height.

Prenatal Growth

The growth of an individual before birth, which is influenced by genetic factors and in-utero environment.

Genetic Influence on Height

The impact of inherited traits on an individual's final adult height.

Environmental Factors

Non-genetic factors that can affect growth and development, such as nutrition and social conditions.

Teratogens

Substances that can cause developmental malformations or birth defects when a developing fetus is exposed to them.

Catch-up Growth

The accelerated growth that may occur after a period of slower growth, often seen in children after nutritional recovery.

Small for Gestational Age (SGA)

A term used to describe infants whose weight and size are lower than the normal range for their gestational age.

Dizygotic Twins

Twins that develop from two separate eggs fertilized by two separate sperm, leading to different genotypes.

Monozygotic Twins

Identical twins that originate from a single fertilized egg that splits into two embryos.

Longitudinal Growth Data

Data collected over time to analyze growth patterns and changes in individuals.

Body Composition Changes

Variations in the proportion of muscle, fat, and other tissues in the body over time.
