Nervous System - basic structure and function

Cells in the nervous system that relay impulses from one cell to another

• neuroglia

• neurons

• astrocytes

• Sattelite cells

The division of the nervous system that includes the brain and spinal cord

• Central nervous system

• peripheral nervous system

• autonomic nervous system

• somatic nervous system

This part of the nervous system that communicates involuntary instructions from the CNS to the skeletal muscles

• Central nervous system

• peripheral nervous system

• autonomic nervous system

• somatic nervous system

What type of neuroglia are found in the PNS

• Sattelite cells

• astrocytes

• oligodendrocytes

• Schwann cells

Myelinating cells found in the CNS that can myelinate more than 1 axon.

• satellite cells

• microglia

• astrocytes

• oligodendrocytes

Which of the following type of microglia is a phagocytic cell found in the CNS?

• astrocytes

• microglia

• oligodendrocytes

• ependymal cells

These cells line the ventricles of the brain.

• ependymal cells

• satellite cells

• Schwann cells

• microglia

Which of the following are functions of the nervous system

• receiving stimuli - sensing

• finding stimuli - searching

• deciding on stimuli - integration

• reacting to stimuli - motor function

Which type of neuron has more than 2 processes from the cell body and is found in the Central nervous system

• unipolar

• bipolar

• multipolar

• tripolar

These neurons are afferent they send messages to the CNS

• motor nerves

• interneurons

• sensory nerves

• multipolar nerves
