B10 Flashcards
Whats the key word called when the body automatically keeps you stable when environent changes
Homeostasis
What are the internal conditions that are controlled in you body
Body temperature
Water content of body
Blood glucose concentration
What does the receptors do
Detect changes in the internal or external environment (known as a change in STIMULI)
What are coordination centres
Ares that recieve and process the information from the receptors. Sending out signals and coordinate the response of the body
Give examples of coordination centres
Brain, Hormonal system and spinal cord
electrical impaulses information sent by a change of stimuli, what does this
Neurons. Thousands and tousands of these are called nerves
CNS stands for?
CENTRAL NERVOUS SYSTEM
Ehat type of neurons carry impaulses from you sense organs to your CNS
SENSORY NEURONS
What is the CNS made out of
BRAIN AND SPINAL CORD
What neuron is called when it coordinates the response to the information, and sends impaulses
MOTOR NEURONS
What is the neuron called when the body gets a response back as a negative feedback
EFFECTORS
Nervous system summed up in order
Stimulus – receptor – CNS – effector
What is the effector organ called when it has a fast reflex
The REFLEX ARC
How do synapses work
The sensory neuron releases its NEUROTRANSMITTERS to pass onto the relay motor when then goes to the muscle
How does the reflext pathway work
Stimulus - receptor - sensory neuron - relay neuron - motor neuron - effector - response
