CNS vs. PNS
This system includes the brain and spinal cord and is responsible for processing and integrating information.
What is the central nervous system?
This structure connects the two cerebral hemispheres.
What is the corpus callosum?
There are this many pairs of cranial nerves in the human body.
What are 12 pairs?
This part of the neuron receives incoming signals from other neurons.
What are dendrites?
This system contains cranial and spinal nerves and serves as the "final common pathway" to muscles and organs.
What is the peripheral nervous system?
This structure acts as the major sensory relay station to the cortex (except for smell).
What is the thalamus?
This cranial nerve is primarily responsible for hearing and balance.
What is cranial nerve VIII (vestibulocochlear nerve)?
This part of the neuron carries electrical signals away from the cell body.
What is the axon?
This division of the PNS controls voluntary movement and sensory input.
What is the somatic nervous system?
This structure is responsible for coordination, balance, and fine-tuning movement.
What is the cerebellum?
This cranial nerve controls facial expression and is also involved in taste.
What is the facial nerve (CN VII)?
This junction is where neurons communicate using neurotransmitters.
What is the synapse?
This division of the PNS includes sympathetic and parasympathetic systems and controls automatic body functions.
What is the autonomic nervous system?
This structure includes the midbrain, pons, and medulla and connects the brain to the spinal cord.
What is the brainstem?
This cranial nerve plays a major role in speech and swallowing by innervating the larynx and pharynx.
What is the vagus nerve (CN X)?
This electrical event involves depolarization and repolarization of a neuron.
What is an action potential?
This system is responsible for integrating sensory input, planning motor behavior, and higher functions like language and memory.
What is the central nervous system?
This system is involved in emotion, memory, and behavior and interacts with both cortical and subcortical regions.
What is the limbic system?
This cranial nerve controls tongue movement and is essential for articulation.
What is the hypoglossal nerve (CN XII)?
These cells support, protect, and provide metabolic assistance to neurons.
What are glial cells?
