Biology (nervous system) Flashcards
Stimulus
Change in your enviromemt
Receptor
Allows us to sence change
Coordinator
The brain tells you what to do(can be spinal cord in reflexive response)
Effector
What leads response muscle/gland
Response
How you react
Neurone
A specialised nerve cell
Nerve impulse
Electrical message that passes along a neurone
Sensory neurone
This carries the nerve impulse from the receptor to the brain/spinal cord
Motor neurone
Carries the nerve impulse from the brain/spinal cord to an effector
Reflex
An automatic response to a stimulus that does not involve conscious thought
Relay neurone
Connects a motor and a sensory neurone in the spinal cord and is involved in a reflexic arc.
Synapse
Junction between two neurones
