40
Function of acetylcholine
cholinergic -
* Learning, short term memory, arousal, reward (delerium), motivation, ACH are higher during wake and REM sleep and lower during NREM sleep

42
Increased levels of acetylcholine are associated with
parkinsonian symptoms (acetylcholine stimulates muscles to conract. Overstimulation causes tremors and jerking movements)
increased levels contribute to motor symptoms. Imbalance of reduced dopamine levels causing muscles to become over excited leading to tremors and other involuntary movements. Dopamine normally acts to inhibit acetlcholine release. when dopamine is low acetylcholine is high.

50
family systems theory
based on the idea that on cant understand a member/part without understanding how all family members operate together (system)
51
Overt rules
* part of family systems therapy
* openly stated and clearly communicated
**Example **- a set curfew, chore responsibilites, expectations regading respectful communication
52
covert rules
Family systems therapy concept that families are governed by unspoken rules, may not be explicity stated, but still guide their actions (family members may not be conciously aware of them).
Example: "dont show weakness", "dont talk about problems", "the father is the decision maker."
53
Boundaries
Family systems therapy
* barriers that protect and enhance functional integrity of families, individuals and subsystems.
54
clearly defined boundary
**family systems therapy**
* maintain individual separateness; emphasizing belongingness
**Example**-a rule where parents maintain privacy regarding personal finances of parents and only allowed to discuss children's allowances
55
Rigid/inflexible boundary
Family systems therapy
* leads to distant relationship and disengagement
Exmple -always having dinner at 6 PM without exception, Always expected to get straight A's without flexibility or adaptation
56
Diffuse boundaries
**Family systems therapy**
* blurred, indistinct, lead to **enmeshment** (an unhealthy level of emotional closeness and interdependence, where individuals struggles to maintain a separate sense of self., excessively involved in eachother's lives, often with one person taking on the emotional role of another.
* **Example** - like a child acting like a parent to their parent leading child to feel they are responsible for parents happiness or constantly trying to fix their problems.
57
Existential Therapy
* emphasizes free will and responsibility, accepting freedom and making responsible choices
* Goal to live authentically and focus on present and personal responsibilities
* understand the patient's subjective experience
* Reflection on life and self-confrontation are encouraged
* Focus on meaning - especially in the face of existential anxieties like death and absurdity of existence
58
Humanistic thearapy - Carl Rogers
* **person-centered therapy**
* Concepts include Self-directed growth and **self actualization**
* Each person has the potential to actualize and find meaning
* Therapis provides unconditional **positive regard** and empathy to foster a supportive environment.
59
main differences between existential and humanistic therapy
*** existential therapy** puts stronger emphasis on exploring the fundamental questions of existence, like death and the meaning of life
*** Whereas humanistic therapy **focuses more on an individual's potential for self actualization (reaching full potential) and becoming the best version of themselves, often assuming a more positive view of human nature.
60
Interpersonal therapy
* **focus on interpersonal issues that are creating distress**
* **TIme-limited**, active, focused on the **present and interpersonal distress**
* Goal is to identify and modify interpersonal problems, to understand and to manage relationsip problems
61

66
Family systems therapy
* AKA **systemic family therapy**
* Focus is on chronic anxiety within families
* goals are to increase the families awareness of each member's function within the family and to increase levels of **self differentiation **(the level at which one's self-woth is not dependent on external relationships, circumstances, or occurences)
*** Triangles:** dyads that form triads to decrease stress; the lower the level of adaptatio, the more likely a triangle will develop
*** Triangles/triangulation, genograms
* Triangles (triads only)**
67
Structural family therapy
* goal is to produce structual change in the family organization to more effectively manage problems
* **Changing transactional patterns and family structure**
* structural mapping (genogram); mapping relationships using symbols to represent overinvolvement, conflict, coalitions, and so forth
*** Hierarchies **- distribution of power
68

5 tanner stages
1. hormones are hard at work behind the scenes: **prepuberty**
2. when the first signs of **puberty begin** -breast buds start, areola expands, downy pubic hair begins growing. The testicles and scrotum grow larger.
3. the** growth spurt**: breast buds continue to grow, no separation betwwn aereola and breast tissue, scant terminal hair, hair forms under the armpits, acne, fat accumulates on thighs and hips. Penis becomes longer and testes gets bigger.
4. t**he continuation of developmen**t: aereola and papilla form a secondary mound above the breast. pubic hair covers entire triangle, breasts become ful
5. the final stage, pubic hair extends into the groin - adult genitals
