Organisation
The two main divisions of the nervous system.
What is the Central Nervous System and Peripheral Nervous System
The part of the a neuron that receives messages from other neurons.
What is a dendrite?
What is a vertebrae?
The part of the brain that controls balance and coordination.
What is the cerebellum?
The branch of the autonomic nervous system that activates the fight, flight or freeze response.
What is the sympathetic nervous system?
The long part of a neuron that carries an electrical impulse away from the cell body.
What is an axon?
The direction that sensory messages travel.
From body to spinal cord/brain.
The lobe that is mainly involved in processing visual information.
What is the occipital lobe?
The hormone released to prepare the body for fast action.
What is adrenaline?
The scientific term for motor neurons.
What are efferent neurons?
The small gap between two neurons.
What is a synapse?
The type of neuron that connects sensory neurons to motor neurons inside the central nervous system
What is an interneuron?
The part of the brain that processes touch, temperature and pain information.
What is the parietal lobe?
The reason why pupils get larger during fight/flight/freeze response.
To allow more light to enter the eyes.
The part of the peripheral nervous system that controls voluntary movements, such as kicking a ball.
What is the somatic nervous system?
Myelin damage can make movement, sensation or thinking slower. Explain.
Myelin insulates axons and speeds impulse transmission, any damage disrupts or slows those signals.
Name the different components of the spinal reflex arc in order.
Receptor --> sensory neuron --> interneuron --> motor neuron --> effector.
A person understand speech but has difficulty producing spoken words after a brain injury. Which lobe is most likely affected?
Frontal lobe (Broca's area)
Why does blood flow redirect away from the digestive system during a fight or flight response?
More oxygen and glucose sent to skeletal muscle/vital organs (heart, lungs etc) so body can react quickly.
The system that controls automatic functions such as heartbeat and digestion?
What is the autonomic nervous system?
The type of cells that produces myelin sheath.
What are Schwann cells?
A person can move their leg but cannot feel touch in it. What type of pathway may be damaged?
Sensory Pathway
The part of the brain responsible for vital life functions such as breathing regulation and heart control.
What is the medulla oblongata?
After danger has passed, which part of the nervous system helps return heart rate and digestion to normal?
The parasympathetic nervous system.
