Unit 2 Flashcards
(78 cards)
Nature vs Nurture
The debate of whether human behavior is determined by genetics or learned through environments (Thomas Bouchard Experiment of identical twins of their IQ)
Biopsychosocial Approach
The approach of biological (genes), psychological (gene expression + beliefs) and social- cultural(peer influence) influences all play a part in our individual development
Endocrine System
Endocrine Gland
- Pineal Gland, Hypothalamus, and pituitary Gland
- Thyroid and parathyroid
- Adrenal glands
- Pancreas
Pineal Gland
- Produce melatonin
- regulate circadian rhythm
Hypothalamus
- control pituitary gland
- trigger hunger and thirst
- maintain homeostasis
Pituitary Gland
- Control growth
- Produce hormones such as oxytocin (pair bonding and social trusts)
Thyroid Gland
- maintain metabolism
Parathyroid
- regulate the level of calcium in blood
Adrenal Glands
- Trigger fight or flight responsesF
Fight or flight Response
Automatic Physiological reaction to an event perceived as stressful or frightening
Pancreas
- Regulate the level of blood sugar releasing inculin
Testis and Ovaries
Reproductive organs in the male and female
Epigenetics
- study of how environmental factors influence gene expression
CNS (central nervous system)
composed of brain and spinal cords
PNS (peripheral nervous system)
connects sensory and motor neurons to the CNS
Somatic nervous system (branch of PNS)
charge of controlling voluntary movements of our skeletal muscle
Autonomic nervous system (branch of PNS)
controls all automatic functions of our internal organs (Such as heart beat or breathing)
Dendrite
Receives information and transfers to the cell body
Axon
Pass message to its terminal branches
Myelin Sheath
A layer of tissue that covers the axon and speeds up neural impulses. Without a myelin sheath, there is a loss of muscle control
Threshold
Minimum level of stimulation required to trigger a neural impulse
all-or-none response
they either fire or they don’t
Excitatory
Pushes neuron’s accelerator, makes a neuron more likely to reach action potential and fire
Inhibitory
Push a neuron’s brake, makes it less likely for a neuron to reach action potential
