biopsychology Flashcards
(35 cards)
what are the 2 subsystems of the nervous system?
- central nervous system
- peripheral nervous system
what is the CNS made up of?
- spinal cord
- brain
what is the PNS further divided into?
- autonomic nervous system
- somatic nervous system
what does the ANS control?
vital functions such as:
- breathing
- heart rate
- digestion
- sexual arousal
- stress responses
what does the somatic nervous system control?
- controls muscle movement
- receives information from sensory receptors
what works alongside the nervous system to control vital functions?
endocrine system
what hormone does the thyroid gland release and what effect does this have?
- releases thyroxine
- affects heart rate(increases)
- also increases metabolic rates
what is the autonomic nervous system further broken down into?
- sympathetic
- parasympathetic
what is the role of the parasympathetic nervous system?
-maintains normal resting state
what does the sympathetic nervous system do?
- prepares the body for fight or flight
- e.g increased heart rate, dilated pupils etc
what happens in a fight or flight response?
stressor perceived –> changes from parasympathetic to sympathetic state –> hypothalamus stimulates pituitary gland –> stimulated adrenal glands produce adrenaline
this is the flight or fight response
what are the 3 types of neurone?
- motor
- sensory
- relay
state the process of a signal crossing a synapse
see page 5 in biopsychology workbook
what is the holistic theory?
the idea that all of the brain is used for all functions
what is the localisation of function?
the idea that different parts of the brain control different areas
who supports the idea of localisations of function?
- Broca
- Wernicke
what are the 4 lobes of the brain?
- frontal
- parietal
- temporal
- occipital
What is the function of the frontal lobe?
this is the motor area
what is the function of the parietal lobe?
- controls somatosensory area
- how we receive sensory information
what is the function of the occipital lobe?
-deals with visual information.
what is the functions of the temporal lobe?
-deals with speech-based information
what is the function of Broca’s area?
-speech production
what is the function of Wernicke’s area?
-understanding language
what will happen is Broca’s area is damaged?
slow speech that lacks fluency
