Case 3 - Histology Flashcards
what is the CNS
brain and spinal cord
what is the PNS
cranial nerves and spinal nerves
what is nervous tissue comprised of
neurones and neuralgia
what are the properties of neurones
irritability and conductivity
what do neurones consist of
nerve cell body called the soma, an axon and one or more dendrites
what are astrocytes
- maintain chemical environment
- provide nutrients
- remove excess neurotransmitter
- contribute to the blood brain barrier
where are astrocytes found
they are neuralgia ion the CNS
function and location of oligodendrocytes
neuroglia that produce the myelin sheath around axons of the CNS neurones and found in the CNS
function of microglia and location
- engulf invading micro-organisms
- migrate to areas of nerve injury to clear dead cells
- found in the CNS
function of ependymal cells
- line the ventricles of the brain and central canal of the spinal cord
- form cerebrospinal fluid and assist in its circulation
- found in the CNS

what does the lateral horn of grey matter Contain
nerve cell bodies of autonomic neurones
function of Schwann cells and where are they found
- produce the myelin sheath around the axons of the PNS neurones
- participate in the regeneration of PNS axons
- neuroglia of the PNS
function and location of satellite cells
- located in the PNS ganglia
- provide metabolic support for the neurones
- remove excess neurotransmitter
arrangement of peripheral nerves
