Question 2

What is nervous tissue made of?

Answer 2

neurons and glial cells

Question 3

What do neurons do and what does each one contain?

Answer 3

sense stimuli and send message to brain; each one has a cell body (life support), dendrites (collect signals from other cells), and axons (transmission ion cable)

Question 4

Answer 4

support, protect, and maintain the function of neurons; forms myelin

Question 5

What does the cardiac muscle do?

Question 6

What are the physical characteristics of cardiac tissue?

Answer 6

has striations and are uninucleate; branching structure

Question 7

Answer 7

by interlaced disks

Question 8
