Chap 5 Flashcards
What are secular growth trends?
changes in physical development from one generation to the next that are largely related to environmental factors
What are the 3 mechanisms of growth?
- Heredity
- Hormones
- Nutrition
Describe how hormones play a role in a child’s growth?
The pituitary gland is responsible for the secretion of growth hormone (GH), that will trigger the mechanisms of growth of muscles and bones. Additionally, thyroxine is a hormone responsible for nervous system development
What are the 3 main challenges to healthy child growth?
- Malnutrition
- Diseases
- Accidents
What are the main diseases that effect child growth?
Malnutrition related diseases make up 45% of child deaths. Other common diseases include, malaria, pneumonia, asphyxiation at birth and diarrhea
What function does the left hemisphere have?
Language production and comprehension, as well as computation and reasoning
What function does the right hemisphere have?
artistic and musical abilities, as well as spatial relationships and facial plus emotional recogntion
Describe the process of the spinal cord forming
The neural plate is the first structure that develops, this plate will then fold over and both ends will be fused shut forming the neural tube. The neural tube will then undergo development and elongation to generate the spinal cord
What is an EEG?
Measures brain waves through its electrical impulses. When performing a task, specific parts of the brain will “light up” and is detectable with this kind of test
What is an FMRI ?
Uses magnetic fields to track the blood flow within the brain
What is a PET scan?
This scan will measure the concentration of glucose in the brain, if a certain part of the brain is being stimulated to perform a task, then glucose levels should be higher at this area
What is an fNRIS?
Similar to an fMRI, it measures blood using infrared light to penetrate the skull. This is a less invasive technique than an fMRI
What are some of the major reflexes of newborn babies?
- Babinski: flexing the foot when touched
- Blinking and sucking
- Palmar: flexing of the hand when an object is place in the palm
- Moro: the outward stretching and pulling in of the arms and legs
What is the dynamics systems theory?
A theory that states that motor development involves many distance skills organized and reorganized over time to meet demands of specific tasks
What is the difference between fine and gross-motor skills?
Fine motor: Includes grasping, holding and manipulating objects
Gross: Includes running, throwing or jumping
