Endocrine System
What is the Endocrine System?
It is a hormonal system that is made up of a bunch of endocrine glands and these glands secrete chemicals called hormones into the bloodstream
The nervous system is made up of the brain and spinal cord and all the neural tissue throughout the body.
What principle does the development of growth follow?
a cephalocaudal principle.
Why are environmental factors are important during the first few months of fetal development?
Size is related more to your environment than to genetics. Genetics won't take effect until the child is born.
Newborns spend most of their time sleeping under what kind of sleep?
REM cycle
Why is the Endocrine System so important?
The variety of hormones made including growth hormone, thyroid hormone amongst others are responsible for our development and keep us alive throughout our lives.
How do nerves fire?
They fire through the use of synapses.
Why do infants and toddlers have disproportionate heads to their bodies?
Growth first appears in the head of infants and toddlers.
What is the definition of a reflex?
Unlearned involuntary response to a stimulus.
What is Brain Lateralization?
The functioning dominance of one part of the brain over the other.
The endocrine system is controlled by a feedback loop where the pituitary gland in the brain will produce hormones.
What is Myelination?
Myelination is the process where the axons of the neurons become covered by a fatty sheath called myelin.
What is the proximodistal principle of growth?
Growth occurs from the inside proximal to the outside towards your fingertips distal
What are the reflexes that are apparent in all newborns?
breathing, blinking, sucking, swallowing, and grasping.
When does brain lateralization occur?
Beginning stages can occur infant-three months. More advanced can occur within the first year.
How many different types of hormones are there?
There are 7 different types of hormones.
Why is Myelination important?
Milan-based with acts like insulation and it helps the transmission of neurons move quickly.
What is the third principle of growth?
Orthogenetic principle
Why are survival refluxes important?
They are essential to keeping us alive (same as the reflexes we are born with)
What are some factors that affect child development?
Environmental, interpersonal, and biological
What are the seven different types of hormones?
Pituitary gland (growth), activated hormones (signal), thyroid (growth, development, and regulation), testosterone (development), estrogen, progesterone (development and regulation), and adrenal androgens (development)
When is our brain development most crucial?
childhood development
What does the orthogenetic principle do?
Goes into the development of the embryo in the fetus where humans develop from a single cell that becomes a full adult human
When do these Primitive reflexes start developing into voluntary actions?
During early months of infancy.
What is the human average life span?
72 years old
