Select the options that describes the Central nervous system (CNS)

• • Consists of brain and spinal cord

• • Protected by cranium and vertebral bones

• • Consists of nerves that

    conduct information from efferent/motor

• • ○  Cranial nerves

  • ○  Spinal nerves

  • ○  Peripheral nerves

Select the options that describes the Peripheral nervous system (PNS)

• • Consists of brain and spinal cord

• • Protected by cranium and vertebral bones

• • Consists of nerves that

    conduct information from efferent/motor

• • ○  Cranial nerves

  • ○  Spinal nerves

  • ○  Peripheral nerves

Nerves are bundled together in structures called:

• • A. Ganglia

• • B. Fascicles

• • C. Myelin sheaths

• • D. Synapses

The outermost layer of a nerve is called:

• • B. Dense connective tissue

• • C. Epithelial tissue

• • D. Nervous tissue

The endoneurium surrounds:

• • A. The entire nerve

• • B. A fascicle

• • C. Individual axons

• • D. The myelin sheath

The endoneurium is made of:

• • A. Dense vascular connective tissue reticular fibers

• • B. Loose vascular connective tissue reticular fibers

• • C. Epithelial tissue

• • D. Muscular tissue

The perineurium surrounds:

• • A. The entire nerve

• • B. One or more fascicles

• • C. Individual axons

• D. Myelin sheath

• E. Only one fasicle

The perineurium is made of:

• • A. Dense connective tissue

• • B. Loose connective tissue

• • C. Tight junctions

• • D. Epithelial tissue
