What type of neuroglial cells form a “blood-brain barrier” membrane to contain the cerebrospinal fluid that the CNS neurons and their pathways depend on for proper impulse conduction?
|
|
ependymal cells
|
|
|
oligodendrocytes
|
|
|
astrocytes
|
|
|
microglia
|
Explanation:
Detailed explanation-1: -Ependymal cells produce cerebrospinal fluid that cushions the neurons. Glial cells of the (b) peripheral nervous system include Schwann cells, which form the myelin sheath, and satellite cells, which provide nutrients and structural support to neurons.
Detailed explanation-2: -Astrocytes and microglia are resident cells of the CNS that contribute to the formation of the BBB.
Detailed explanation-3: -Answer and Explanation: Ependymal cells line the brain and spinal cord and are involved in the production and circulation of cerebrospinal fluid which works to protect the brain by cushioning it.
