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?
corpus callosum
what does the human hindbrain comprise of
medulla,pons, cerebellum
where is the hypothalamus situated
forebrain
floor of 3rf ventricle
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,
nissle’s granules in a nerve cell are now identified as
ribosomes
ivan pavlov performed experiments on
conditioned reflexes
sodium pump stops operating during
action potential
dendrites of a motor neurone are generally more
branched
which type of neurone is most prevalent in the body
multipolar neuron
which part of nervous system controls actions like walking and and running
somatic nervous system
gray matter is primarily composed of
neuron somas
the spinal cord is continuous w which part of the brain
medulla oblangata
the part of the forebrain which lies below cerebrum
thalamus
the part of the forebrain which lies below cerebrum
thalamus
sensory area that recieves impulses from the skin are contained by which of the following
parietal lobe
the brain is divided into — main parts
3
which part of the brain is involved in sleeping and waking
hypothalamus
the auditory relay center is found in
midbrain
which part increases the surface area of the brain
cerebral cortex
which part of the brain is responsible for our primitive emotions
limbic system
what is the cerebral cortex responsible for
screening all incoming sensory data
and is involved in conscious activity
sensory neuron is also called
afferent
cerebral spinal fluid is found in between
pia matter and arachnoid matter
hypothalamus is a part of
diencephalon
control center of hearing and speech
cereBrum 🥁
swallowing and vomitting (reflex) is regulated by
medula oblangata
which hemisphere is speech and language area located in
left cerebral hemisphere
a single neuron can conduct — impulses per second
120
which part of nervous system controls walking and running 🏃♀️
somatic nervous system
brachial plexus supply to
upper limbs
