sensory perception Flashcards
what is an exteroreceptor ?
An exteroceptor is a receptor
that is located near a stimulus in the external environment, such as the somatosensory receptors that are located in the skin.
What is an interoreceptor ?
An interoceptor is one that interprets stimuli from internal organs and tissues, such as the receptors that sense the increase
in blood pressure in the aorta or carotid sinus.
what is a proprioreceptor ?
a proprioceptor is a receptor located near a moving part of the body,
such as a muscle, that interprets the positions of the tissues as they move.
what are the associated functions with the frontal lobe ?
According to The Human Medicines Regulations 2012, is it legal to sell one of the blister strips of paracetamol 500mg tablets (8 tablets) from a sandwich shop
what are some symptoms of brain tumours affecting the frontal lobe ?
Personality change Loss of inhibition leading to offensive behaviour which is out of character for that persone.g. swearing, rudeness, inappropriate sexual behaviour Irritability Aggression Apathy – loss of interest in life Difficulty planning or organising Weakness of one side of the face or body Problems walking Difficulty speaking
what are some associated functions of the parietal lobe ?
perception and integration of sensory information (e.g. touch, pressure, temperature, and pain) visuospatial processing spatial attention spatial mapping number representation
what are some symptoms of a brain tumour affecting the parietal lobe ?
Loss of sensation in part of the body
Sensory or motor neglect – e.g. a person with right sided sensory neglect will not respond to a sound, gesture or touch from or on the right but will respond normally to these stimuli on the left side.
Difficulty speaking or understanding speech
Problems with reading and/or writing
what is a function of the occipital lobe ?
vision
what is a symptom of a brain tumour affecting the occipital lobe ?
This area is responsible for vision; symptoms include problems with or loss of vision on one side. Blindness that is caused by damage to the visual area of the brain is called ‘central’ or ‘cortical’ blindness.
what are some associated functions of the temporal lobe ?
Recognition Perception (hearing, vision, smell) Understanding language Learning and memory Emotional reactions Associated cognitive disorders Schizophrenia is the cognitive disorder most closely aligned to temporal lobe dysfunction.
what are some symptoms of brain tumours affecting the temporal lobe ?
Fits – may be called ‘temporal lobe Epilepsy’
Short term memory problems
Inability to recall words
what are some associated functions of the cerebellum ?
coordination of voluntary movement motor–learning balance reflex memory posture timing sequence learning
