|
|
|
The most numerous glial cell
|
Astrocytes
|
|
|
State the main function and physical characteristics of astrocytes
|
highly branched neuroglia associated with the blood-brain barrier
|
|
|
This glial cell is responsible for myelination of axons in the CNS

Oligodendrocytes can myelinate up to 50 nerve fibers
|
|
|
Describe the physical characteristics of oligodendrocytes
|
Square-shaped glial cells with short processes.
|
|
|
Discuss the role of microcytes.
|
These cells can transform into large phagocytotic cells in response to tissue damage. [defense system]

|
|
The cerebellum and medulla oblongata are outgrowths of this part of the brain stem.
|
Hindbrain
|
|
|
This part of the CNS is responsible for coordination of movement and muscle activity.
|
Cerebellum
|
|
|
This part of the brain regulates vital activities such as breathing.
|
