Nsca-Cpt Chapter I

Front 1

composes wall of heart
involuntary

Back 1

cardiac muscle

Front 2

lines internal orans and is involuntary

Back 2

smooth muscle

Front 3

muscle that attaches to the skeleton via tendons

Back 3

skeletal muscle

Front 4

agonist

Back 4

initiates the desired movement

Front 5

antagonist

Back 5

opposes the moving (agonist) muscle

Front 6

3 properties of skeletal muscle

Back 6

1. elasticity-stretch
2. extentisibility-ability to returnt to resting length
3. contractility-ability to shorten and produce tension

Front 7

3 muscle actions

Back 7

1. concentric-muscle overcomes load and shortend
2. eccentric-mucle lengthens
3. isometric-muscle doen't shorten or lengthen

Front 8

sarcoplasmic reticulum

Back 8

stores calcium

Front 9

Transverse tubules

Back 9

pass through muscle fiber. carry impulses and transport substances

Front 10

Sarcomere

Back 10

smallest funtional unit of muscle

Front 11

describe the sliding filament theory of muscle contraction

Back 11

1. action potential is received from motor neuron
2. SR releases calcium in to sarcoplasm
3. calcium binds with troponin
4. troponin shifts tropomyosin off of binding site on the actin
5. myosin attaches to actin and with ATP performs a power stroke
6. Actin slides over myosin

Front 12

Muscle spindles

Back 12

-located in the muscle
-measure length change and speed of length change
-signal muscle contraction

Front 13

Golgi tendon organs

Back 13

-located in musculotendionous region
-recognize change in muscle tension
-signal muscle to relax

Front 14

Axial skeleton is composed of

Back 14

skull
vertebral column
sternum
ribs

Front 15

Appendicular skeleton is composed of

Back 15

shoulder girdles
arms
legs
hips

Front 16

shapes of bones

Back 16

long
short
flat
irregular

Front 17

bone tissue is also called

Back 17

oseous tissue

Front 18

hematopoiesis

Back 18

formation of red and white blood cells

Front 19

bone grows longitudinally as long as _______ _______ remain open

Back 19

Epiphyseal plates

Front 20

After epiphyseal plates close, bone grows in

Back 20

thickness

Front 21

resorbtion

Back 21

loss of bone tissue

Front 22

List the 3 types of bone cells and what they do

Back 22

1. osteoclasts-destroy bone
2. osteoblasts-form bone
3. osteocytes-mature osteoblasts

Front 23

Tendons

Back 23

connect muscle to bone
