Lobes of the Brain
The frontal lobe is responsible for higher cognitive functions such as reasoning, problem-solving, decision-making, voluntary movement, and speech production.
What is the frontal lobe responsible for?
There are 12 in this category.
How many cranial nerves are there?
The basic functional unit of the nervous system.
What is a neuron?
This part of the brain is responsible for balance and coordination.
What is the cerebellum?
These nerves carry sensory information from the body to the CNS.
What are afferent (sensory) nerves?
This lobe processes sensory information such as touch, temperature, and pain and helps with spatial awareness.
What is the parietal lobe responsible for?
The facial nerve - CN VII.
Which cranial nerve controls facial expression?
This is the gap between two neurons where neurotransmission occurs.
What is a synapse?
The largest part of the brain, responsible for higher-order thinking and voluntary actions.
What is the cerebrum?
The PNS is divided into the somatic nervous system and this system, which controls involuntary functions.
What is the autonomic nervous system?
This lobe contains Wernicke’s area.
What is the name of the area the temporal lobe contains?
Controls phonation and swallowing through the laryngeal muscles.
What is the function of the vagus nerve - CN X in speech?
A major excitatory and major inhibitory neurotransmitter.
What are glutamine and GABA?
This structure connects the brain to the spinal cord and controls basic life functions like breathing and heart rate.
What is the brainstem?
This part of the autonomic nervous system prepares the body for "fight or flight" responses.
What is the sympathetic nervous system?
The occipital lobe is located at the back of the brain and is responsible for visual processing.
Where is the occipital lobe located?
Damage to this cranial nerve results in sharp facial pain, difficulty chewing, and loss of sensation in certain areas of the face.
What is the trigeminal nerve - CN V?
This speeds up signal transmission along the axon.
What is the role of myelin in neural conduction?
This protective barrier prevents harmful substances from entering the brain from the bloodstream.
What is the blood-brain barrier?
This large nerve extends from the lower back down the leg and is the longest nerve in the body.
What is the sciatic nerve?
This lobe contains the Broca’s area.
What area does the frontal lobe contain?
This cranial nerve carries auditory and balance information.
What is the vestibulocochlear nerve - CN VIII?
This is a process where action potential jumps from node to node along myelinated axons.
What is saltatory conduction?
This part of the CNS relays sensory information to the cerebral cortex.
What is the thalamus?
This cranial nerve is responsible for controlling heart rate, digestion, and other autonomic functions.
What is the vagus nerve?
