Nervous Tissue

• Dendrites

• Axon Terminals

• Myelin Sheath

• Schwann Cells

What is the function of the nerve cells?

• They are responsable of your defense mechanism.

• They transmit signals or messages to other neurons, organs or glands.

• They transmit substances to your endocrine system to produce hormones.

The protective fatty tissue that speeds up the transmission of messages is:

• Myelin Sheaths

• Axon

• Dendrites

• Soma

An axon conducts nerve impulses _________ the cell body.

• away from

• toward

• both toward and away

• around, bypassing

• white mater, gray mater

• pink mater, gray mater

• gray mater, white mater

• blue mater, pink mater

• cardiac muscle

• skeletal muscle

• smooth muscle

• nervous

The small cells that provide support, insulation and protection in nervous tissue are called:

• dendrites

• intercalated discs

• dendrites

• glial cells

Slender processes that extend from the bodies of neural cells are called

• axons and dendrites

• neuroglia

• intercalated discs

• striations

Which characteristic applies to both muscle and nervous tissues
