Neuron types Flashcards
3 neurons, what they look like, what they do!
What are the 3 types of neurons
-Motor
-Sensory
-Inter
Sensory neurons functions and description points?
-take information from the receptors TO the central nervous system for processing
-connected to receptors
-cell body pops out the side (so cutesy)
Motor neurons functions and description points?
-take messages FROM the central nervous system to muscles in the body (effectors), which then carry out the response
-connect to effectors (muscles or glands)
-cell body in/next to dendrites (fattie)
Inter neurons functions and description points?
-the connector neurons which occur in between different types of neurons (usually connect sensory and motor)
-carry info through spinal and brain
-connect sensory and motor
-big dendrites on the top and small cell body below
What are some other names for interneurons?
relay or connector
What is another name for nerve cells?
Neurons?
What is the most common neuron?
Motor
Do neurons have gaps? Why?
-gap between each neuron
-they were all touching, then when the brain sent of a signal all the nerves would “fire” off at once (imagine having one switch for all the lights in your house)
How do neurons communicate?
-info travels down neuron (dendrites to axon) as an electric impulse
-neurotransmitters carry the impulse from one to the next
-neuros are chemicals that are released into the space between
-drifts out of synaptic terminal
What is the electric impulse called and what is it?
-neurotransmitters is the name and it is in the chemical game
What is the space between each neuron called?
-Synapse
-neuros flow across it
where are neurotransmitters stored and when are they released?
-stored in vesicles
-released into synapse when a nerve impulse reaches the axon terminal
what happens when it reaches the dendrite?
-dendrites recieve a chemical messgae and send out an electrical signal
summary of cycle quickly!!
-Receptors stimulate sensory neuron to send information to the CNS.
-Interneurons translate message in CNS to motor neuron.
-Motor Neuron sends message from CNS to the effector.
myelin shealth does and looks like
-curved rectangular looking ahh
-insulates the axon to speed up the nerve impulse
dendrites does and looks like
-curly hair spiderweb funkybum
-recieve info from other neurons or receptors
axon does and looks like
-thin long tube (ayo)
-carries electrical nerve impulse away from the cell body towards axon terminals
cell body does and looks like
-circle thingamabob
-contains nucleas and other controling parts of the cell
axon terminal does and looks like
-idk what it looks like
-pass on info to the next neuron via synapse
