Study Notes

Interior Brain Parts

Brainstem: Connects the spinal cord and the brain; contains the reticular activating system (RAS)
RAS: Responsible for brain alertness
Limbic System: Located above the brainstem, it generates emotions and processes emotional memories
Thalamus: Plays a key role in memory and many cognitive functions
Hypothalamus: Monitors the internal system to maintain homeostasis, or the body's normal state
Hippocampus: Essential for consolidating learning and converting information to long-term storage
Amygdala: Involved in emotions, particularly fear

Exterior Brain Parts

Frontal lobe: Responsible for planning, thinking, and contains the "self-will" area or personality
Temporal lobes: Process auditory information, including sounds and language
Occipital lobe: Located at the back of the head, responsible for visual processing
Parietal lobe: Focuses on spatial orientation, calculation, and recognition
Motor cortex: Controls body movement and works with the cerebellum to coordinate learning motor skills
Somatosensory cortex: Processes touch signals received from the body

Additional Brain Components

Schwann cell: Produces myelin sheath
Neurogenesis: The creation of new neurons
Cerebrum: Largest part of the brain, associated with higher-order thinking and decision-making
Gyri: Folded bulges on the cerebrum
Fissures: Deep furrows on the cerebrum
Sulci: Shallow furrows on the cerebrum
Corpus Callosum: Connects the left and right hemispheres of the brain
Cerebellum: Coordinates voluntary movements and balance
Dendrites: Receive signals from other cells
Axon: Transfers signals to other cells and organs
Synapse: The gap between neurons
Myelin sheath: Speeds up signal transmission
Nucleus: Controls the entire neuron

Mental Well-being

Also known as psychological well-being
Refers to a state free from mental or emotional disorders
Psychologically well-adjusted adolescents can problem solve realistically, make informed choices, and display resilience

Mental Health Challenges/Disorders

Eating Disorders
- Anorexia nervosa: Fear of weight gain, distorted body image, and dangerously low body weight
- Bulimia nervosa: Similar to anorexia, involves binge eating followed by purging behaviors (vomiting, excessive exercise)
Anxiety Disorders
- Phobic Disorder: Intense, irrational fear of specific objects, situations, or activities causing distress and disruption in daily life
- Panic Disorder: Sudden, intense feelings of fear and stress ("panic attacks")
- Obsessive-Compulsive Disorder (OCD): Intrusive thoughts (obsessions) and repetitive behaviors or rituals (compulsions) to reduce anxiety
Major Depressive Disorder (MDD)
- Also known as clinical depression
- Persistent sadness, loss of interest in activities, and various physical and emotional symptoms
Bi-polar Disorder
- Characterized by rapid shifts in mood, from happy to sad, with intense highs and lows
Conduct Disorder
- Repeated pattern of behaviors violating the basic rights of others
Personality Disorders
- Enduring patterns of thoughts, emotions, and behaviors that deviate from cultural expectations, causing distress or impairment
- Paranoid Personality Disorder: Persistent distrust and suspicion of others
- Antisocial Personality Disorder: Disregard for and violation of others' rights
- Histrionic Personality Disorder: Excessive attention-seeking, need for approval, and intense emotional expression
- Narcissistic Personality Disorder: Inflated sense of self-importance, need for admiration, lack of empathy
- Avoidant Personality Disorder: Intense feelings of inadequacy, sensitivity to criticism, and fear of rejection
- Dependent Personality Disorder: Excessive need to be taken care of, submissive and clingy behavior, and fear of separation
- Obsessive-compulsive Personality Disorder: Preoccupation with orderliness, perfectionism, and control
