Nervous System Flashcards
What are the two different nervous systems
Central nervous system
Peripheral nervous system
What does the central nervous system control
Brain and spinal cord
What cells can you find in the central nervous system
Oligodendrocytes
What are the two divisions of peripheral nervous system
Motor and sensory
What are the two nervous systems that make up the motor division in the peripheral nervous system
Somatic
Autonomic
What does the somatic NS control
Skeletal muscles
What does the autonomic NS control
Smooth, cardiac muscles and glands
What are the two nervous systems within the autonomic nervous system within the motor division within the Peripheral nervous system?
Parasympathetic
Sympathetic
What would be a way of describing the parasympathetic nervous system?
Resting and digesting
How would you describe the sympathetic nervous system?
Fight or flight
What are the two nervous tissues?
Neurons
Neuroglia
What makes up neuroglia?
Astrocytes
Microglial
Where do you find neuroglia?
Central nervous system
When you see Schwann cells what nervous system are you looking at
Peripheral nervous system
What are the three types of neurons
Sensory neurons
Interneurons
Motor neurons
A unipolar neuron structure would be what kind of neuron
Sensory
What does a sensory neuron look like?
Two axon terminals on both ends covered in myelin sheath and the nucleus and cell body in the middle
What is an example of a multipolar neuron structure?
Motor neurons
What is an example of a bipolar neuron structure?
Interneuron
What does a multipolar motor neuron look like?
Cell body and nuclei with dendrites and one long axon terminal covered in Mylien sheath
