Which statement regarding nervous tissue is true?
Dendrites contain Nissl bodies.
Sensory Neurons conduct nerve impulse to CNS.

Pseudounipolar neurons can be found in the olfactory epithelium
Nervous tissue is highly vascularized
Which statement regarding glial cells is true?
Protoplasmic astrocytes are present in the gray matter of the CNS.
Schwann cells form myelinated and unmyelinated coverings over axons of the PNS
THeir function is the metabolic and mechanical support and protection of neurons.
Ependymal cells can be ciliated in some regions.
Astrocytes belong to mononuclear phagocytic system
Fibrous Astrocytes form pedicels (vascular feet)
Microglial cells are macrophages of CNS
Which statement regarding neuron is true?
Nissl bodies are found in perikaryon and dendrites.
Most neurons have only one dendrite.
Neuron is metabolic inactive cell.
Multipolar has many axons and one dendrite.
Pseudounipolar can be found in the spinal cord
Its composed of perikaryon and processes
Which statement regarding ganglia is true?
Multipolar neurons are present in autonomic ganglia
Sensory ganglia are surrounded by connective tissue capsule
Are divided into sensory or an autonomic ganglia
Are surrounded by endoneurium
Are composed of both perikaryons and nerve fibers
Are composed of nerve fibers only
Which statement regarding unmyelinated axons is true?
Schwann cells envelop multiple axons
Nodes of Ranvier are commonly visible along unmyelinated nerve fibers
Myelin sheath wraps each axon.
Schwann cells envelop just one axons
Which statement regarding epineurium is true?
Surrounds the whole nerve
Contains the blood vessels.
Is covering the CNS
Is covering axons and Schwann cells
Have a rich network of reticular fibers
Is dense, irregular fibrous connective tissue
Which connection: cells - place of presence, is correct?
Satellite cells - ganglia
Oligodendrocytes - PNS
Ependomocytes - central canal
Microglial - central nervous system
Schwann cells - CNS
Which statement regarding interneurons is true?
Can connect motor neurons with sensory neurons.
Can be multipolar neurons.
Creates the majority of neurons in the human CNS
Are a type of sensory neurons.
Their axons are always myelinated.
Which statement regarding lemmocytes is true?
Form myelinated fiber in CNS
Are called also Schwann cells
Are present in the PNS
Surround and insulate PNS axons and myelinate those having large diameters
Sheath composed of lemmocytes will not form myelin around the axons
Allows for faster action potential propagation along an axon in the PNS
What is true about meninges?
Dura mater is separated from the arachnoid by subdural space
Dura mater is composed of loose CT
Subarachnoid space is filled with cerebrospinal fluid
Blood vessels penetrate the CNS through tunnels covered by pia mater
Which element are present in white matter
Oligodendrocytes
Microglia
Myelinated axons
Fibrous axons
Dendrites
Neuron bodies
Choroid plexus
Contains dense CT
Located in the ventricles of the brain
Contains non-fenestrated capillaries
Contains ependymal cells
Contains cuboidal/columnar ion - transporting cells
Which elements form blood-brain barrier?
Basement membrane
Endothelial cells with tight junctions
Endothelial cells with gap junctions
Foot-like processes of astrocytes
Cerebrospinal fluid:
Is produced by choroid plexus
Fills ventricles of the brain
Is present in subarachnoid space
Is present in the perivascular space
Protects against mechanical shock
Spinal cord:
Anterior horn contains multipolar neurons
Anterior horn contains unipolar neurons
Gray matter is inside
In spinal cord gray matter is located centrally, white peripherally
In spinal cord gray matter is located peripherally, white centrally
Find true sentence about CNS development:
At the cranial end of neural plate is wider and consists of the region where the brain will arise
Metencephalon gives the beginning to pons and cerebellum
Nervous system appears at the beginning of the third week of pregnancy
The neural plate is recognizable as the thickening of the ectoderm opposite to the primitive streak
At the caudal end neural plate is narrower and gives rise to the spinal cord
