Coordination - Coggle Diagram
Coordination
RECEPTORS
sensory cells that senses stimulus present in the sense organs.
Ear-Cochlea
Eyes-Retina
Tongue-Taste buds
Weak response- won't be able to produce a strong response
Strong response- produce a strong response
Synapse
neuron>gap<neuron
junction where two neurons meet
synaptic cleft
vesicles- containing neurotransmitters on one neuron and receptor transmitters in the other neurone.
Central nervous system
brain
protected by the skull
spinal cord
protected by vertebral column
co-ordinates responses
EFFECTORS
Muscles
Organs or glands that produce a response to the stimulus.
Peripheral nervous system
nerves
connecting different parts of the body
carry the messages called electrical signals and chemical messages in the form of sodium and potassium ions.
neurotransmitter
sense organs
senses any change in the environment
Reflex arc
external stimuli
sensed by sensory cells called receptors
passes the cells to sensory neurones
then passes it to relay neurone
motor neurones
effectors
muscles and glands
the pathway of a reflex action where the conscious parts of the body aren't involved.
so that the message is sent quickly
Stimulus
any change in the internal or external environment
Nervous system
transmits messages in the form of electrical and chemical signals
sensory neurons
relay neurones
motor neurones
nerve- collection of neurons
