Flashcards in Muscle and Nervous Tissues Deck (27):
1

Tissue that is specialized to contract or shorten to produce movement

Muscle tissue

2

How many directions does muscle tissue move?

1

3

What are the 4 functions of muscle tissues?

Movement, stabilize body positions, regulate organ volume, thermogenesis

4

What are the 3 types of muscle cells?

skeletal, cardiac, smooth

5

What muscle cells are striated?

skeletal and cardiac

6

What 2 muscle cells are involuntary?

cardiac, smooth

7

What is the major characteristic of skeletal muscle?

strength

8

What is the major characteristic of smooth muscle?

endurance

9

What is the major characteristic of cardiac muscle?

strength, endurance

10

What is the difference between skeletal and cardiac muscle?

Cardiac muscles have branches

11

Where can the skeletal muscle be found?

tendons, bones

12

Where can the cardiac muscle be found?

heart, major arteries

13

Where can the smooth muscle be found?

organs, viscera

14

Transmit nerve impulses, aides in their transmission

nervous tissue

15

Where are nervous tissues found?

brain, spinal cord, peripheral nerves

16

brain and spinal cord

CNS

17

What are the 3 functions of nervous tissue?

Sense change in environment, integrates and interprets, sensory input for understanding, responds by contractions or glandular secretions

18

What are the 2 types of nervous cells?

neurons and neuroglial cells`

19

Receive and conduct electrochemical impulses from one part of the body to another

neuron

20

Specialized cells of the nervous system that produce myelin, communicate between cells maintain ionic environment, and nurture the differentiation of neurons

neuroglial cells

21

How much do neuroglial cells occupy the CNS?

half

22

Are neurons or neuroglial cells bigger?

neurons

23

What does it mean if the neuroglial cells stay mitotic?

Fill in spaces of injured neurons after disease and injury; go in to the G0 phase and can be repaired

24

A by-product of muscle contraction is heat production and is therefore important in homeostasis of body temperature

Thermogenesis

25

Sustained contractions of smooth muscle to prevent outflow from hollow organs and maintain them at important volume

Regulating organ volume

26

Insulation for nerve tissue

Myelinated

27

No myelin around nerve

Unmyelinated
