receptor function Flashcards
what do recptors do
detect changes in the surroiunding which acts like a stimulus specific to a specific stimulus
how is each receptor adapted
to detect a different type of stimulus
what do they do to energy
convert energy into nerve impulses at the sensory neurone energy transducers
what needs to be reached and why
a threashold needs to be reached to produce a generator potential
what do rods and cone in the retina detect
light stimuli and wavelength
WHAT do olfactory cells detect
presence of volatile characteristics
what do taste buds detect
presence of soluble chemicals
what do parcipion corpuscle detect
pressure on the skin
what do cochlea detect
vibration in the air
how is the strength of stimulus reflected
increases the rate of nerve impulses fired
where is the pacinian corpuscle found
on the skin in the deep skin such as finger soles, or in the joints
what does it detect
mechanical stimuli
whats its structure like
contain one nerve ending wrapped in connective tissue called lamella
why is it located in the joint
to show the change in direction of movement of the joint
what does the membrane contain
sodium ion channels
