midterm 1 Flashcards
what is health psychology
Health promotion and maintenance
Prevention and treatment of illnesses
Ethology and correlates of health, illness and dysfunction
Impact of health professionals on people’s behaviour
Why people get ill and how they respond to illness
Early time
- something is wrong with your mind and its influencing your body
- their linked
Greek- humoral theory
- when things go away from homeostasis your ill
- essential fluid is linked to personality and behaviour
Middle ages
- level of health is related to degree of faith
- religion infiltrates medical knowledge
renaissance
-rejection of humoral theory
due to microscopy and autopsy
dualism
-mind and body are separate
conversion hysteria
-psychological conflicts are converted into physical symptoms
Psychologipsychomatic medicine
-Dealing with psychological issue to cure illness
Biopsychosocial
What we consider healthy changes over time
health=not constant
System theory- all connected (macro/micro)
central nervous system
- carries voluntary nerve impulses to skeletal muscles and skin
- carries involuntary impulses to muscles an glands
- includes brain and spinal cord
peripheral nervous system
- outside the brain and spinal cord
- includes somatic and autonomic nervous system
somatic nervous system
-controls voluntary movement
autonomic nervous system
- controls organs that operate involuntarily
- includes sympathetic and parasympathetic nervous system
sympathetic nervous system
- mobilizes the body for action
- response to danger
parasympathetic nervous system
- maintains and restores equilibrium
- calms down after dangerous situations
Hindbrain
- oldest part of the brain
- includes medulla,pons & cerebellum
medulla
-mediates heart rate and blood pressure, controls respiration
pons
links hindbrain and midbrain
cerebellum
voluntary muscle movement (processes for basic function)
Midbrain
connects hindbrain to forebrain
forebrain
- newer part of brain
- 2 parts diencephalon and telencephalon
Diencephalon
thalamus- relay senses and stimulus
hypothalamus-cardiac function
telencephalon
cerebral cortex- higher order intelligence (frontal, temporal, parietal, occipital lobe)
endocrine system
- system that secretes hormones into blood
- pituitary gland and adrenal gland
anterior
- secretes hormones for growth
- promotes protein synthesis
- darkening of skin
posterior
-preserves bodies water
pituitary gland
anterior lobe and posterior lobe
adrenal gland
adrenal medulla and adrenal cortex
adrenal medulla
-releases hormones that help react to stress
adrenal cortex
-releases hormones necessary for life (regulate metabolism and stress response)
cardiovascular system
heart, blood vessels and blood
blood
- provides oxygen to cell
- manages pH and carbon dioxide
- secretes hormones
- gets rid of waste
- blood carries O2 from lungs to tissue and CO2 expels from breath
left side of heart
- takes in oxygenated blood from lungs
- distributes to organs
right side of heart
-sends deoxygenated blood back to the lungs from organs
systole blood pressure
- hearth contracts
- lets oxygenated blood out
diastole blood pressure
- hearth is relaxing
- deoxygenated blood enters hearth
respiratory system
- provides oxygen to body
- removes carbon dioxide from body
- regulates blood in body
Infection is transmitted by
- direct transmission:touching
- indirect:sneezing
- biological:biological catalyst changes composition of infection
- mechanical:organism is not changing the virus
Immune response
natural immunity,specific immunity, humoral immunity, cell-mediated immunity
natural immunity
- first
- always working
- macrophages:removes threat by swallowing it
- natural killers: recognizes infection
specific immunity
- comes in if natural immunity needs help
- T-cells:kills particular pathogen
Humoral immunity
- protects against bacteria
- neutralizes viral infection
cell-mediated immunity
cytotoxic: responds to specific antigens
helper T:enhance function of cells
stress response
- cerebral cortex labels event as stressful
- signal sent to hypothalamus
- activates nervous system
- acute stress
- flight or fight response
- sympathetic arousal
