Biopsychology Flashcards
What does the spinal cord do
Recieves and transmits info to the brain
What does the brain do
Maintains life and is involved in higher functions and processes
What is the peripheral nervous system made up of (2)
Somatic nervous system
Autonomic
What is the somatic nervous system
Transmits info to and from the senses
What is the autonmicnnervous system
Transmits info to and from internal organs
What is the sympathetic nervous system
Increases bodily activity
What is the parasympathetic nervous system
Maintains or decreases bodily activity
What are the three types of neutrons
Sensory
Relay
Motor
What are the sensory neutrons
Tell the brain about external and internal environment
They process info taken from the senses
What are relay neutrons
Connect motor and sensory
Carry messages from one part of CNS TO ANOTHER
What is the motor neurone
Carrys signals from CNS
What is synaptic transmission
Process for transmitting messages from neuron to neuron
What’s a synapse
Gap between neutrons where chemical signals pass through
Describe the process of synaptic transmission
Nerve impulse travels down neuron and prompts release of neuro transmitter
Chemicals are released into synaptic fluid
The receptors of the post synaptic neuron take up the chemicals from fluid and convert them into electrical impulses
What’s excitation
When it’s more likely for a neuron to fire
