Flashcards in Muscle Tissue Study Guide Deck (16):
1

What are the three types of muscle tissue?

Skeletal, cardiac, smooth

2

What are the five functions of muscle?

skeletal movement, maintain posture, support soft tissue, guard entries/exits, and maintain body temperature

3

Name the smallest contractile unit of a muscle

sarcomeres

4

Provide another term for muscle cell

muscle fiber

5

What are the connections for connecting muscle to bone?

tendon/aponeurosis

6

Define fascicle

bundle of muscle fibers

7

Define motor unit

neuron and muscle fibers it stimulates

8

What protein makes up thick filaments

myosin (thing: actin)

9

What is the area of the sarcomere where there are no thick filaments?

I Bands

10

What are the three connective tissues in skeletal muscle and what do they cover?

epimysium: entire muscle, perimysium: covers fascicles, endomysium: surrounds individual muscle fibers

11

What is the neurotransmitter for skeletal muscle tissue?

acetycholine

12

Starting with sacromere, build the layers of the skeletal muscle.

sarcomeres, myofibril, muscle fiber, fascicle, whole muscle

13

What are the two types of muscle contractions?

Isometric: builds up tension in muscles but no movement, isotonic: movement occurs

14

What is the rule of muscle tissue?

Use it or lose it

15

What are the effects of exercise on muscles?

Bigger/stronger/better endurance

16

what are the special properties of muscle tissue

much larger, multinucleated, humerous mitochondria, contractibility, irritability
