Chapter 4 body, brain, and health Flashcards
Celiac disease
An inherited digestive problem in which gluten triggers and immune response that leads to inflammation and damages the small intestine
Celiac disease can damage the villi of the small intestine leading to malnutrition
Catch up growth
After a period of malnutrition or illness, reflects the body struggle to get back on the growth course it is genetically programmed to follow
Endocrine glands
Secrete chemicals called hormones directly into the bloodstream
Pituitary gland
Controlled by the hypothalamus of the brain, triggers the release of hormones from all other endocrine glands by sending hormonal messages to those glands
Growth hormone
Produced by the pituitary gland, it triggers the production of specialized hormones that directly regulate growth
Pineal gland
Produces melatonin, which helps us fall asleep
Parathyroid glands
Four small glands behind the thyroid that influence bone growth
Adrenal glands
Produces adrenaline, also known as epinephrine, our flight or fight hormone
Hypothalamus
Connects the endocrine system to the nervous system
Thyroid gland
Produces thyroid hormone which controls metabolism
Thymus gland
Produces white blood cells that help fight infections
Pancreas
Makes insulin and glucagon to maintain balance of sugar in bloodstream and cells
Ovaries
Make estrogen and progesterone to regulate menstrual cycle and maintain a pregnancy
Testes
Make testosterone which is involved in sperm production
Androgens
Testosterone and other male hormones
Estrogen
The primary female hormone at puberty stimulates the production of growth hormone, and is responsible for the development of breasts, pubic hair and female sex organs for the control of menstrual cycles throughout a woman’s reproductive years
Progesterone
Called the pregnancy hormone, it orchestrates bodily changes that allow conception and then support a pregnancy
Neuron 
Contain three main parts of the dendrites which receive messages the cell body; and the axon, which sends messages across the synapse to other neurons
Myelination
Incases neurons and speeds transmission; begins prenatally, but continues for many years after birth
Cephalocaudal principal
Which means growth occurs in a head to tail direction
Proximodistal principle
When the chest and internal organs form before the arms hands and fingers during the prenatal period
