General Concepts of Muscles/ connective tissue

Question 1

ligament

Answer 1

dense fibrous connective tissue that attaches bone-bone, bone-cartilage, or cartilage-cartilage
serves to hold structures together and keep stable

Question 2

tendon

Answer 2

attach muscle-bone/cartilage/fascia and help move

Question 3

intracapsular

Answer 3

located inside articular cartilage
synovial membrane goes around
ex: cranial cruciate ligament

Question 4

extracapsular

Answer 4

located outside articular cartilage
ex: collateral ligament

Question 5

menisci

Answer 5

fibrocartilage that helps in adaptation of articular surfaces
in stifle joint

Question 6

disc

Answer 6

fibrocartilage that totally seperates joint cavity in 2 compartments, helps with adaptation and movement of surfaces
in temporo-mandibular joint

Question 7

circumduction

Answer 7

movement of part in a circle

Question 8

supination

Answer 8

lateral rotation of limbs causing palmar surface to face medially

Question 9

pronation

Answer 9

medial rotation of limbs causing palmar surface to face caudally

Question 10

adduction

Answer 10

movement toward median

Question 11

abduction

Answer 11

movement away from median

Question 12

joint capsule

Answer 12

composed of synovial membrane and fibrous layer

Question 13

synovial membrane

Answer 13

filter blood to create synovial fluid
prevents friction

Question 14

articular cartilage

Answer 14

prevents bone-bone friction

Question 15

articular villi

Answer 15

inside synovial membrane
increase surface of membrane to create more fluid

Question 16

capsular lg

Answer 16

thickenings of fibrous capsule that forms bands or triangles

Question 17

yellow lg

Answer 17

contain elastic fibers that gives yellowish color

Question 18

smooth muscle

Answer 18

involuntary, no striations
ex: intestines

Question 19

cardiac muscle

Answer 19

involuntary, branched
ex: heart

Question 20

skeletal muscle

Answer 20

striated, voluntary
ex: biceps brachii

Question 21

motor unit

Answer 21

a given motor neuron and all muscle fibers it controls

Question 22

small motor unit

Answer 22

very fine control
one neuron and one muscle fiber

Question 23

large motor unit

Answer 23

do not need fine control
one neuron and several hundred muscle fibers

Question 24

agonist

Answer 24

muscles that produces an action

Question 25

syndergist

Answer 25

helper muscles of agonist muscles

Question 26

antagonist

Answer 26

muscles that oppose the agonist muscles action

Question 27

fixator

Answer 27

muscle that fix a joint, preventing the movement

Question 28

belly of muscle

Answer 28

red, fleshy part that is contractile

Question 29

attachments

Answer 29

connective tissue proper that joins muscle to bone, cartilage, other muscles

Question 30

origin

Answer 30

less mobile attachment

Question 31

insertion

Answer 31

more mobile attachment

Question 32

bursa

Answer 32

sac between bone and tendon, prevents friction

Question 33

tendon sheath

Answer 33

synovial sheath around synovial fluid

Question 34

retinaculum

Answer 34

regional thickening of deep fascia that bind tendon in a place at certain joints
