The brain
Name one part of the brain
Cerebrum / Cerebellum / Medulla
What are nerve cells called?
Neurons
What is the gap between a neuron called?
Synapse
Define a hormone
Chemical messengers
What are the types of diabetes
Type 1 and Type 2
Which part of the brain controls balance and coordination?
Cerebellum
Name the three types of neuron
Sensory, inter, motor
How do signals cross a synapse?
Neurotransmitters
Where are hormones released into?
Bloodstream
People with type 1 diabetes are unable to produce?
Insulin
I am responsible for unconscious activities
Medulla
What is the role of a sensory neuron?
Carries impulses from receptors to CNS
What happens after the chemical crosses the synapse?
What is a target tissue?
Tissue with receptors for a hormone
Which organ controls blood glucose?
Pancreas
Describe the function of the cerebrum
Conscious thought, intelligence, memory
Put these in order: motor neuron, sensory neuron, inter neuron
SIM
Sensory -> Inter -> Motor
Why are synapses important?
Allow communication between neuron's
Why do only certain cells respond to a hormone?
They have specific receptors
Why do blood glucose levels stay high in diabetes?
No insulin / insulin resistance
A patient has poor balance after injury - which part is likely damaged?
cerebellum as It controls coordination and balance
Explain how a message travels from a stimulus to a response
Receptor -> sensory neuron -> CNS -> motor neuron -> effector
Explain what would happen if synapses did not work properly?
Messages wouldn't pass between neurons -> no response / slow reactions
A hormone travels in the blood but has no effect on a cell. Why?
the cell does not have the correct receptor
Compare 2 differences between Type 1 and Type 2 diabetes
Type 1 = no insulin, treated with medication, lifelong
Type 2 = insulin resistance, treated mainly with lifestyle, can be resolved
