skin conductance and the nervous system Flashcards
why do we sweat
cooling down, gain grip when threatened
what are the two types of sweat glands
eccrine and apocrine
what is the eccrine sweat gland
all over the body
what is the aprocine sweat gland
armpits, genitals
what are the different types of nervous systems
CNS - the brain and spinal cord
peripheral - sympathetic and autonomic
autonomic- sympathetic (fight or flight), parasympthetic (rest or digest)
immune system
what is electrodermal activity
small changes in electrical activity of the skin after interacting with a stimulus
how is electrodermal activity measured
units of conductance (microsiemens or micromnos)
what is the use of measuring electrodermal activity
the measure of sympathetic arousal, measure of emotional impact of stimuli and can be used as a lie detector
what is spatial orientation
the vestibular system
what creates spatial orientation
objects, forces, chemical gradients, social mores, energy gradient and beliefs
where is the vestibular
in the inner ear
what are the parts of the vestibular
the otoliths, utride, saccule and the superior, posterior and lateral semicircular canal
what are the functions of the vestibular system
spatial orientation, balance, walking, standing, stabilising vision, blood pressure regulation
what are examples of vestibular clinical problems
vertigo, minor inbalance, dizziness (drugs or alcohol), vection (the illusion that you’re moving when your e not)
