2. Control & Communication Flashcards
The cerebrum controls
memory, personality, conscious thought,
The cerebellum controls
balance and co-ordination
The medulla controls
heart rate & breathing rate
The CNS is made up of the
brain and spinal cord
The sense organs contain receptors which detect
stimuli
Sensory neurons carry information from the
sense organs to the CNS
Inter neurons connect the
sensory and motor neurons
Motor neurons carry information from the
CNS to effectors
Effectors are usually
muscles or glands
The tiny gap netween neurons is called a
synapse
A reflex action helps to
protect our body from harm
A reflex action is
Rapid, Automatic and Protective
Hormones are released by
endocrine glands
Hormones are chemical messengers which are transported in
the blood
Hormones are transported to
target organs
Target organs have specific
receptors on their surface
The pancreas helps to control
blood glucose levels
Insulin converts
glucose to glycogen
Glucagon converts
glycogen back into glucose
Glycogen is stored in the
liver
Type 1 diabetes usually develops
early in life
Type 2 diabetes usually develops
later in life
