Stressor Response
Help!
|
|
||||
|---|---|---|---|---|---|
| anger, fear, anxiety, and excitement | emotional stress
🗑
|
||||
| trauma, fever, haemorrhage, surgery, and malnutrition | physical stress
🗑
|
||||
| stress response is initiated by the | hypothalamus
🗑
|
||||
| short term stress | The Alarm Reaction
🗑
|
||||
| long term stress | The stage of resistance
🗑
|
||||
| The body needs the ability to suddenly mobilise resources (Glucose), particularly to the heart and skeletal muscles, to allow for “fight or flight | Purpose of GAS
🗑
|
||||
| Hypothalamus projects descending axons to autonomic nuclei in the medulla oblongata that influence | HR, BP, digestive activities and respiration
🗑
|
||||
| Hypothalamus projects descending axons to | autonomic nuclei
🗑
|
||||
| autonomic nuclei are in the | medulla oblongata
🗑
|
||||
| Interneuron in the spinal cord stimulates the pre-ganglionic sympathetic nerve fibres to stimulate | Adrenal medulla
🗑
|
||||
| Adrenal medulla releases | 80% epinephrine and
20% nor-epinephrine
🗑
|
||||
| more potent stimulator of metabolic activities (rise in glucose), bronchial dilation, and increased blood flow to skeletal muscles and the heart. | Epinephrine
🗑
|
||||
| has a greater influence on peripheral vasoconstriction and blood pressure | Norepinephrine
🗑
|
||||
| The action potential travels from the limbic system to the | hypothalamus
🗑
|
||||
| new action potential is generated by the hypothalamus and sent via | descending sympathetic fibre
🗑
|
||||
| Alarm reaction (short term stress response) causes increase in: | HR, BP, RR, metabolic rate, sweating, bronchiole and pupil dilation, glucose release to blood
🗑
|
||||
| Alarm reaction (short term stress response) causes decrease in: | digestive system activity, urine output
🗑
|
||||
| During the stage of Resistance or long term stress response Hypothalamus releases | Corticotropin releasing hormone( CRH)
🗑
|
||||
| CRH acts on | anterior pituatary gland
🗑
|
||||
| Anterior pituatary gland releases | Adrenocorticotropic hormone (ACTH)
🗑
|
||||
| ACTH acts on | adrenal cortex
🗑
|
||||
| adrenal cortex releases | cortisol
🗑
|
||||
| cortisol blood levels rise, inhibiting | CRH and ACTH
🗑
|
||||
| during cortisol release negative feedback, the hypothalmus releases CRH into | hypothalamo-hypophyseal portal system
🗑
|
||||
| cortisol is carried by what through systemic circulation | proteins like Albumin
🗑
|
||||
| gluconeogenesis, lipolysis, protein catabolism in all tissues bar hepatocytes and inhibits lipogenesis in fat tissue | cortisol effects
🗑
|
||||
| stimulates the liver to break down fats, encourages glycogen breakdown, acts as glucose sparing hormone | growth hormone
🗑
|
||||
| stimulates metabolism and increase in glucose blood levels | thyroid hormones
🗑
|
||||
| Na & H2O retention, dcrs in cap perm. formation of prostaglandins/leukotrines, stab. lysosomal membr. inhibits phagocytosis & suppresses T-Lymphocytes, inhibits connective tissue repair | long term cortisol effects
🗑
|
||||
| nervous tic, fatigue, depression, anxiety, overreating, insomnia, HTN, CAD, IBS, sexual dysfunction, hair loss, autoimmune disease, tension headach | State of exhaustion
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
