AP Psych Mod 10

QuestionAnswer
Central nervous system brain and spinal cord
peripheral nervous system -connects central nervous system to rest of the body
Somatic nervous systen -controls voluntary movements -part of the peripheral nervous system
Brain -control center of central nervous system -makes decisions
spinal cord -carries messages from brain to rest of the body
sympathetic nervous system -alerts and speeds up body -Ex: dilate eyes, increase heart rate, and decrease digestion -part of autonomic system -"fight or flight"
parasympathetic nervous system -relaxes and slows down body -Ex: closes eyes, slows heart rate, and increases digestion -part of autonomic system
autonomic system controls involuntary body functions like heart rate, digestion, and breathing without conscious thought
Sensory neurons -detect stimuli (such as senses) and send information (via electrical signals) to the central nervous system
motor neurons -carry information from central nervous system to muscles and glands
Interneuron -the connector between sensory and motor neurons that allows them to communicate between each other -cause reflexes by making this connection
Neural network interconnected neurons that process and transmit information in the brain
Endocrine system -controls hormones by using glands
Hormones -chemicals that influence emotion and desires
Difference between endocrine and nervous system -Nervous system= Fast Endocrine=slow -Endocrine message lasts a long time Nervous system lasts a short time
epinephrine -adrenaline (hormone that speeds up body reactions)
pituitary gland -releases growth hormones and oxytocin -controls other glands (master gland) -located in core of brain
oxytocin -a social bonding hormone
adrenal gland on top of kidneys and release epinephrine and norepinephrine (adrenaline and noradrenaline) - increases heart rate, blood pressure, blood sugar
Order of movement of electrical impulse (message) from brain to endocrine system brain > pituitary > other glands > hormones > body
Leptin hormone that decrease hunger and regulates energy balance and storage
Melatonin hormone that regulates sleep-wake cycles
Ghrelin hormone that stimulates hunger
pineal gland regulate the body's sleep pattern by producing and secreting melatonin
reflex -an automatic, involuntary response to a stimulus, - a sensory neuron detects the stimulus-> sends a signal to the central nervous system which then activates a motor neuron to produce a quick response in a muscle or gland.
