Nervous System Protection
These bony structures protect the brain and spinal cord.
What are the skull and vertebrae?
The PNS includes all nervous tissue located outside of what two structures?
What is the brain and spinal cord?
This type of neuron carries information toward the CNS.
What is Sensory/Afferent neuron?
Chemicals that allow neurons to communicate with one another are called this.
What is Neurotransmitters?
These three layers surround and protect the brain and spinal cord.
What are the meninges?
These nerves carry information between the spinal cord and the rest of the body.
What is Spinal nerves?
This type of neuron carries information away from the CNS.
What is Motor/Efferent neuron?
Neurotransmitters are released from this part of the neuron.
What is Axon terminal?
This is the tough, outermost layer of the meninges.
What is the dura mater?
An area of skin supplied by the sensory fibers of a single spinal nerve is called this.
What is a dermatome?
This type of neuron connects neurons within the CNS and helps process information.
What is Interneuron?
Neurotransmitters cross this small gap between neurons.
What is Synapse?
This fluid surrounds the brain and spinal cord and helps protect them.
What is cerebrospinal fluid (CSF)?
A doctor wants to determine which spinal nerve is responsible for controlling a particular group of muscles. What would they examine?
What is myotome?
Put these steps in order: motor response, sensory information, integration.
What is Sensory → Integration → Motor?
A drug that increases or decreases the normal activity of a neurotransmitter can change communication between these cells.
What is neurons?
This space is located between the arachnoid mater and pia mater and contains cerebrospinal fluid.
What is the subarachnoid space?
Several spinal nerves combine and reorganize their nerve fibers before traveling to the arm. What structure are they forming?
What is a plexus?
Your heart continues beating without you consciously telling it to. Which nervous system division allows this to happen?
What is Autonomic nervous system?
A drug interferes with neurotransmitter communication at a synapse. What nervous-system process is being disrupted?
What is communication between neurons?
