Finally, in adults, the head represents approximately 12% of the body length. The cephalocaudal trend is also the trend of infants learning to use their upper limbs before their lower limbs. The proximodistal trend, on the other hand, is the prenatal growth from 5 months to birth when the fetus grows from the inside of the body outwards.
After birth, babies first gain control over their lips and tongues, then their eye movements, followed by control over their neck, shoulders, arms, hands, buttocks, fingers, legs, and feet. There is a genetic cephalocaudal (head-to-foot) trend in both prenatal and postnatal development.
Child development involves the biological, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence. It is—particularly from birth to five years— a foundation for a prosperous and sustainable society .
Early childhood is a stage of rapid growth, development and learning and each child makes progress at different speeds and rates. [13] It is essential to integrate physical training designed in accordance with the anatomical characteristics andage-related characteristics of a child's development, to ensure the normal physical development of ...
Physical development. Typically grows between 1 and 1.5 inches (2.5 and 3.8 cm) and gains about 2 pounds (910 g). [20] Motor development. Hands kept in tight fists. [21] Equal movement of arms and legs on both sides. [21] Able to briefly hold up head when in prone position. [21] Arm thrusts are jerky. [22] Brings hands close to eyes and mouth. [22]
From birth, the ovaries of the human female contain many immature, primordial follicles. These follicles each contain a similarly immature primary oocyte . At puberty , clutches of follicles begin folliculogenesis, entering a growth pattern that ends in ovulation (the process where the oocyte leaves the follicle) or in atresia (death of the ...
Plant development is the process by which structures originate and mature as a plant grows. It is studied in plant anatomy and plant physiology as well as plant morphology. Plants constantly produce new tissues and structures throughout their life from meristems [ 36 ] located at the tips of organs, or between mature tissues.
Another notable example includes the development of sensory systems, which also undergo plastic changes during critical time periods. [32] [6] [33] A lesser known example, however, remains the critical development of respiratory control during developmental periods. At birth, the development of respiratory control neural circuits is incomplete ...
