Neurology Flashcards
What’s the nervous system made up of
Nerons
How do nerve impulses pass to each other
Through synapses
What are the senses
Hearing touch sight taste
What’s nerve cells joined together by
Synapises
What’s the part of a neuron
Cell body
Finer dendrites
Axon
Myelin sheath
Axon terminal
How big is a neuron
A few mm - meter long
Dendrons split into dendries do what
Takes info into neutron
What is in the pre synaptic terminal
Chemical transmitters
When a cell reaches the end on a neuron what happens
Calcium is pumped into the neuron
Cerebrospinal fluid is found between which two meniges?
Above the pla matter and below the arachnoid mater
Which two electrolytes are essential for nerve impulse to pass down the axon and to another neurone
Sodium and calcium
Which part of the brain is difficult to see in a gross specimen
Midbrain
Which main structures make up the brain stem
Midbrain pons and medulla
Why is Greg matter found on the outmost region of the cerebrum
Nerves travel here synapse in the grooves of the cerebrum and then travels elsewhere
Why is the olfactory bulb sometimes called the ol factory lobe?
In some species like dogs the olfactory bulb is so large that it appears as a separate lobe
