Like all cells in the body, neurons have a cell body containing a nucleus. But unlike other cells, neurons have a distinctive ability: they can communicate with other cells, using a cluster of fibers called dendrites at one end. Dendrites receive messages from other cells. At their opposite end, neurons have a long extension called an axon, the part of the neuron that carries messages destined for other neurons. Neurons do not actually touch one another. Rather, they communicate with other neurons by means of chemical messengers, neurotransmitters, that travel across the small gaps, known as synapses, between neurons. Although estimates vary, infants are born with between 100 billion and 200 billion neurons. In order to reach this number, neurons multiply at an amazing rate prior to birth. At birth, most neurons in an infant's brain have relatively few connections to other neurons. During the first 2 years of life, however, a baby's brain will establish billions of new connections between neurons. Furthermore, the network of neurons becomes more complex. The intricacy of neural connections continues to increase throughout life. Child care authorities agree: For the first 12 months of life, there is no better food for an infant than breast milk. Breast milk not only contains all the nutrients necessary
for growth, but it also seems to offer immunity to a variety of childhood diseases, such as respiratory illnesses, ear infections, diarrhea, and allergies. Breastfeeding for as little as 4 months reduces infections by an average of 45 percent, and the reduction in infection is 65 percent lower for 6 months of breastfeeding compared to formula-fed babies. Breast milk is more easily digested than cow's milk or formula, and it is sterile, warm, and convenient for the mother to dispense. There is
even some evidence that breast milk may enhance cognitive growth, leading to high adult intelligence. the model that seeks to identify the way that individuals take in, use, and store information -In
a study by developmental psychologist Karen Wynn, infants first were shown an object—a 4-inch-high Mickey Mouse statuette. A screen was then raised, hiding the statuette. Sets with similar termsWhat is the typical weight gain lbs of an infant between the first and second year of life?Between ages 1 and 2, a toddler will gain only about 5 pounds (2.2 kilograms). Weight gain will remain at about 5 pounds (2.2 kilograms) per year between ages 2 to 5. Between ages 2 to 10 years, a child will grow at a steady pace.
What is the typical weight gain of an infant between the first and second year of life quizlet?Birth-weight typically doubles by five months (to 15 pounds) and triples by the first birthday (to 22 pounds). The baby gains only 5 to 6 pounds in the second year, and 4 to 5 pounds in the third year. Height increases by about half in the first year (to 30 inches) and by an additional 5-6 inches in the second year.
What is the approximate energy requirements of infants in kcal/kg of body weight?Another way to generalize caloric need is that an infant needs 100cal/kg/day, ages 1 to 3 years need 80 kcal/kg/day, 4 to 5 years needs 70kcal/kg/day, 6 to 8 years needs 60 to 65 kcal/kg/day and 9+ needs 35 to 45 kcal/kg/day.
What approximate age does the normal infant first develop the ability to swallow food?At first, babies learn how to swallow solid foods such as pureed or mashed foods you feed them from a spoon. Most babies can swallow a spoonful of pureed foods without choking when they are around 6 months old. Babies can start to use a spoon by themselves at around 10 to 12 months old.
