HKR 2300 Growth and Development Midterm with correct answers 100% Motor development - Correct Answer The continuous, age-related process of change in movement as well as the interacting constraints (or factors) in the individual, environment, and task that drive these changes. The change you see simply by getting older. Growth - Correct Answer Quantitative increase in size or mass Maturation - Correct Answer Qualitative advance in cell, organs or body systems. Thing we don't always see. What are the 3 main perspectives from lecture 1 - Correct Answer Maturational perspective, information processing perspective and Ecological perspective. What are Newell's 5 Constraints - Correct Answer Individual structural, Individual functional, Environmental Physical, Environmental socicultural and Task Newtons 1st law - Correct Answer Objects in motion stays in motion until acted upon by a force. Newton's 2nd law - Correct Answer F = m x a OR a= F/m Newton 3rd law - Correct Answer For every action there is an equal and opposite reaction Rotating limbs - Correct Answer An objects linear velocity is the product of its rotational velocity and radius of rotation. Stability - Correct Answer Resistance to movement Balance - Correct Answer Maintain equilibrium What are the 2 ways and 2 directions for prenatal growth? - Correct Answer The influence on growth - Correct Answer Genetics; timing and rate of growth. Extrinsic factors can slow growth; malnutuition, illness/ injury. PHV - Correct Answer peak height velocity PWV - Correct Answer peak weight velocity. Newell's individual structural constraint explains this. 5 systems from Lecture 3 - Correct Answer Skeletal, Muscular, Adipose, Endocrine, Nervous. Cessation - Correct Answer Growth at the epiphyseal plates stops at different times for different bones. Usually stops by age 18/19. Younger ages in girls. Occification - Correct Answer The process of laying down new bone material. What are the endocrine hormones? - Correct Answer Growth hormone, Thyriod hormone, Estrogen and Testosterone. What is a Neural Network? - Correct Answer Interconnected neural cells. signal speed though the network by myelin sheaths. Movements - Correct Answer Movements can be categorized as either. Spontaneous or Infantile reflexes. Reflexes - Correct Answer Not all reflective movements disappear many are incorporated to later situational movements. They are important for motor development. There are three types primitive postural and locomotor. Stereotypies - Correct Answer Rhythmic movements primative reflexes - Correct Answer Protective, survival and nutrition. postural reflexes - Correct Answer Practice for maintaining bal
