MED 10000 Anatomy of a growing child Summary

Anatomy of a Growing Child
The 4 main realms of growth

- Functional Growth
- Physical Growth
- Emotional Growth
- Reproductive Growth

FUNCTIONAL GROWTH

- Main influences on the developing brain: hereditary and environment
- The different realms of brain growth:
o The serve and return method
o Stress
o Toxic Stress
o Executive Function and Self-regulation
- Key areas of neurodevelopment:
o Sensory and Motor Function
o Language
o Visual-spatial
o Memory
o Social Cognition
o Executive Function
- Ages of Key Functional-Gait Maturation:




PHYSICAL GROWTH

The growth of long bones

- Growth hormone produced in Pituitary Gland causes production of Insulin-like Growth
Factor 1
- Muscle and cartilage cells then multiply
- Biggest area of influence is on the epiphyseal plates
- Epiphyseal plates consist of cartilage
- Insulin-like Growth Factor 1 then causes cartilage to calcify and form bone
- Therefore, leading to growth

Control of growth hormone secretion

- Production is modulated by stress, exercise nutrition, sleep and by GH itself
- Primary controllers are two hypothalamic hormones and one from the stomach
o Growth hormone releasing hormone (GHRH)
▪ Stimulates the synthesis and release of GH
