Which statement regarding nervous tissue is true?

Dendrites contain Nissl bodies.

Sensory Neurons conduct nerve impulse to CNS.

Neuronal signals are conducted faster in electrical synapses than in chemical

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?

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

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
