Pelvic Muscles

Question 1

Articulations

Answer 1

equivalent to joints

All joints permit free movement (T/F)

Answer 2

False

Question 3

How can you tell if a muscle generates a lot of force

Answer 3

its fibers are not parallel to the tendon

Question 4

bony muscle attachement

Answer 4

fibers connect to bone

Question 5

non-bony muscle attachement

Answer 5

fibers eventually get to bone (fascia first)

Question 6

Bony attachments are stronger than fascia attachments (T/F)

Answer 6

False
Fascia is stronger

Question 7

Do muscles flex

Answer 7

no
Joints do

Question 8

Fibrous joints

Answer 8

bones connected by dense CT (ligaments)

Question 9

Mobility of fibrous joints

Answer 9

limited
more stretchy when young

Question 10

cartilaginous joints

Answer 10

Bones connected by cartilage

Question 11

cartilaginous joint movement

Answer 11

some movement

Question 12

fibrous joint examples

Answer 12

interosseous ligament
tooth anchor
skull sutures

Question 13

examples of cartilaginous joints

Answer 13

epiphyseal plate
pelvic symphysis
vertebrae joints

Question 14

synovial joints

Answer 14

bones separated by fluid filled cavity (capsule)

Question 15

synovial joint movement

Answer 15

highly movable

Question 16

examples of synovial joints

Answer 16

movable appendage joints

Question 17

Why do synovial joints move so much

Answer 17

they have space to adjust, similar to a bursa

Question 18

Why is a synovial joint called a potential space

Answer 18

it is a fluid filled cavity that lacks air or circulation

Question 19

Why do joints crack

Answer 19

joint capsules have a defined volume
when the size of the capsule changes space is filled with the state change making a noise

Question 20

Simple synovial joints

Answer 20

one pair of articular surfaces

Question 21

composite synovial joints

Answer 21

> 2 articular surfaces
ex: stifle

Question 22

Synovial joint types

Answer 22

plane
pivot
ellipsoidal
spheroidal
hinge
condylar
saddle

Question 23

plane joints

Answer 23

Flat connection (no gap)
ex: b/w vertebrae
Limited movement (one plane)

Question 24

pivot joints

Answer 24

notch and ball
ex: axis to atlas or radius to ulna
rotational movement

Question 25

Ellipsoidal joints

Answer 25

round convex and concave surfaces (almost ball and socket) quite a bit of movement ex: wrist

Question 26

Saddle joint

Answer 26

flat concave to flat convex surfaces movement in one plane (no side to side) ex: phalanges

Question 27

spheroidal joints

Answer 27

ball and socket most movement possible in a joint ex: hip

Question 28

hinge joints

Answer 28

ridges and groves allow movement on only one plane ligaments hold steady ex: fetlock and elbow

Question 29

what holds hinge joints in place

Answer 29

collateral ligaments (one on each side)

Question 30

condylar joints

Answer 30

2 condyles (knuckles) on concave surfaces mostly hinge movement (some sliding and rotation)

Question 31

What prevents condylar joint from moving left and right

Answer 31

collateral ligaments

Question 32

what prevents condylar joints from rotating

Answer 32

cruciate ligaments (crossed)

Question 33

Stifle (knee) joints have...

Answer 33

shock absorbers called menisci

Question 34

Menisci

Answer 34

c-shaped fribrocartiaginous discs shock absorbers and rotation preventers

Question 35

Cranial cruciate ligament

Answer 35

stifle joint prevents femur sliding caudally during weight bearing

Question 36

caudal cruciate ligament

Answer 36

prevents femur from sliding cranially while bearing weight

Question 37

What is the difference between the wrist and the ankle

Answer 37

wrist flexes the same as digits ankle flexes opposite the digits

Question 38

muscles that flex the toes...

Answer 38

extend the ankle

Question 39

muscles that flex the fingers...

Answer 39

flex the joints

Question 40

Where does abduction or adduction of the arm happen

Answer 40

the shoulder

Question 41

where does abduction or adduction of the leg happen

Answer 41

the hip

Question 42

Medial rotation of the foot =

Answer 42

plantar surface faces medially

Question 43

lateral rotation of the foot=

Answer 43

plantar surface faces laterally

Question 44

there are less pelvic muscles then thoracic muscles (T/F)

Answer 44

False

Question 45

Why do pelvic appendages have more muscles

Answer 45

for locomotion power

Question 46

agonist of hip flexion

Answer 46

iliopsoas

Question 47

agonists of hip extension

Answer 47

middle glut and biceps femoris

Question 48

agonist of hindlimb aBduction

Answer 48

middle glut and biceps femoris

Question 49

agonists of hip flexion

Answer 49

iliopsoas

Question 50

agonists of hindlimb aDduction

Answer 50

adductor magnus et brevis (dogs) adductor magnus (cats)

Question 51

Agonists of medial femur rotation

Answer 51
