Control and coordination Flashcards
what are nociceptors
they respond to potnetially damaging stimuli that result in pain
what are meissner corpuscles
a type of mechanoreceptor responsible for touch sensitivity
what is unique about photoreceptors
they are the only sensory recpetor cell that is depolarised at rest (in the dark) -35
and hyperpolarised to a light stimulus 70mV
the photosensitive compound in the human eye is made up of
opsin and retinal
destruction of the anterior horn cells of the spinal cord would result in
voluntary motor impulses
the fovea centrails is the place of most distinct vision that consists of
high density of cones, but no rods
what is the function of the cerebrum
intelligence, memory, reasoning though and judgement, learning AND SKELETAL MUSCLES
what is the function of the cerebellum?
controls muscular acticity such as typing, running,
the activity of the two cerebral hemispheres is coordinated by?

what does vagus nerve affect
arises from the side of the medulla
mixed nerve . 10th cranial nerve
controls VISCERAL movements and sensations
heartbeat, respiratory movements, peristalsis, sound production,
nissleβs granules in a nerve cell are now identified as
ribosomes
ivan pavlov performed experiments on
conditioned reflexes
sodium pump stops operating during
