Know What Neurons And Synapses Ure Flashcards
Neuron
-A cell in the body & brain
-Responds to stimuli in the environment or within the body
-Communicates Information through the nervous system using
-Electrical and chemical processes
Sensory neurons
-Converts external stimuli from the environment
Into electrical impulses
Replay neurons
-Transmits electrical impulses with the CBS
Motor neurons
-Transmits impulses from the brain to the muscles or glands.
Central nervous system
- Made up of brain and spinal cord
- helps brain and body communicate
- passes messages backward and forward
- sends messages to brain via spiral cord
- brain sends message to body via spinal cord (makes body move)
(dopamine (role in attention and learning, if not enough dopamine it makes it difficult to concentrate on tasks ) serotonin (plays a role in mood, make people feel depressed))
Synapse
- Small gap at the end of A neuron that allows a signal to pass from one neuron to the next
- released by a impulse of neuron
- goes across the synaptic cup
- taken up at the receptors of another neuron
Synaptic functioning
-Involves the communication between the neurons using neurotransmitters
Role of the central nervous system (CNS)
- made up of brain and spinal cord
- helps brain and body communicate
- passes messages backwards and forwards
- senda messages to brain via spinal cord
- brain sends message to body via spinal cord (makes body move)
