Adolescence (12 - 20 Years Old) ATI Flashcards
During this stage, you transition from childhood to adulthood =
Adolescence
Adolescence literally means-
“Grow and mature”
Bridges the gap between dependence and independence =
Adolescence
Puberty begins during-
Preadolescence
The stage of development usually between 11 and 13 =
Preadolescence
Puberty takes years to complete and may last through the end of-
Can puberty continue even after most of the physical changes related to it have taken place?
Adolescence
Yes
What does puberty begin with?
A growth spurt in height & weight + the development of secondary sex characteristics
When does puberty end in females?
The onset of Menarche (First Menstrual Period)
When does puberty end in males?
The onset of Spermarche (Sperm Production)
The stage of development in which you become sexually mature =
Post-Puberty (Still in Adolescence)
The onset of puberty is influenced by-
Genetics, Environmental Factors, & Gender
Which gender typically experiences puberty first?
Typically it impacts females first
While variations can occur in the age of onset, duration, and pace of the physical changes of puberty, the sequence of these changes is-
Pretty consistent from person to person
What results in the emergence of sexual differences between females and males in regard to adult body size, composition, and shape?
The rapid growth and development during puberty
Primary sex characteristics =
Primary sex organs that are present at birth + involved with reproduction
Secondary sex characteristics =
Breasts in females, pigmented facial hair in males
Do secondary sexual characteristics play any role in reproduction?
No, they just appear during puberty
Pubic hair is initially -
It eventually becomes-
Sparse + Lightly Pigmented
Grows Darker + Coarser
During puberty in males, what happens to the larynx (voicebox) and vocal cords? What does this result in?
They increase in size, resulting in a deepened voice
In females, some changes of puberty include:
Fat distribution changes, there is also an increase in the width + roundness of the hip and pelvic regions
Both females and males produce what during puberty?
What does this cause?
Sebaceous glands that become larger and more active.
Causes Acne.
Puberty causes awkward stages, both in their appearance and their-
Physical Coordination
Hormonal changes during puberty are triggered by -
The Hypothalamus
How does the hypothalamus trigger the hormonal changes during puberty?
It begins releasing Gonadotropin-Releasing Hormone (GnRH)
When GnRH is produced, where is it taken? Then what does it do?
It’s transported to the anterior pituitary gland, then stimulates the secretion of gonadotropins
What are the two different types of gonadotropins?
Follicle Stimulation Hormone (FHS)
Luteinizing Hormone (LH)
FSH stimulates the development of-
Eggs in females + Sperm in males
LH stimulates the-
Testes to secrete testosterone + Ovaries to secrete estrogen
Testosterone + Estrogen stimulate the development of-
Primary + Secondary Sex Characteristics
Influence the physical growth spurt in adolescence
What happens to the brain during adolescence?
It becomes more complex and the number of folds increases.
Unused brain pathways are eliminated as myelination increases
Unused brain pathways are eliminated during adolescence, this process is called-
Synaptic Pruning
The brain becomes more efficient and functional during-
This causes-
Adolescence
Major Cognitive Changes
Cognitive functioning in an adolescent is-
Rapid
The brain capacity for these 3 things matures during adolescence:
Attention, Memory, Cognitive Processing
Some of the most significant changes to the brain in adolescence occur in the-
Prefrontal Cortex
The anterior area of the brain that’s involved in decision making, abstract thinking, problem solving, and impulse control =
The Prefrontal Cortex
Paradoxically, while adolescents are developing the ability to think like adults, they are often-
Risk Takers
Adolescents are prone to-
Giving into peer pressure
Is it true that some scientists believe that adolescent are genetically wired to be risk takers?
Why?
Yes.
It could be an evolutionary benefit that helps build the confidence + motivation needed to leave your family + begin a life of your own
What happens to the heart and lungs during adolescence?
What does this lead to?
They increase in size + compacity
Increased strength + Endurance
What happens to the stomach and intestines during adolescence?
They increase in size + compacity
Eye-Hand Coordination + Dexterity Improves During-
Adolescence
Psychosocial changes occur at what kind of pace during adolescence?
A Rapid Pace
Are Psychosocial changes almost as dramatic as the physical changes associated with puberty?
Yup
When do people develop a sense of identity?
During Adolescence
Peer relationships become more important than family ones during-
Adolescence
Is it normal during adolescence to experience a strong desire to conform to their peer group due to their need for acceptance + belonging?

Adolescence
Both males and females tend to become unhappy with -
Their appearances during adolescence
Adolescents require a lot of iron to make-
A well-met caloric intake is necessary to support-
Calcium is needed for-
Extra Hemoglobin.
Proper Growth & Development associated with puberty.
The extra bone growth.
Why do males require additional hemoglobin during adolescence?
Because of increased muscle mass
Why do females require additional hemoglobin during adolescence?
Because of blood loss during menstruation
In some cases, adolescents will rely extensively on-
This can cause problems like-
Fast foods + unhealthy food choices
Obesity or disordered eating
What happens in terms of teeth during adolescence?
The second molars erupt
By the end of adolescence, what happens to your jaw?
It reaches and adult size
By early adulthood, what kinds of teeth appear?
Third Molars (Wisdom Teeth)
What’s one of the most widely unmet health care needs of adolescents?
Oral Health
Why might adolescents be at a higher risk for dental issues?
Sports Injury, Oral Piercings, High Sugar Intake, Nicotine Initiation, Orthodontic Considerations
Lifelong dental health habits are created during-
Childhood + Adolescence
