Final Lymph, Sacrum/Pelvis

Question 1

Lymph

Answer 1

excess tissue fluid
network of lymphatic vessels that withdraws lymph from interstitial fluid compartment

filters lymph through nodes
returns it to bloodstream

Question 2

Lymph flow from extracellular spaces

Answer 2

Blood capillaries
–> afferent lymphatic vessel
–> lymph node (filtration occurs here)
–> efferent lymphatic duft

Question 3

Answer 3

right superior quadrant of body drains to venous systems via this duct

Question 4

Thoracic duct

Answer 4

left superior qyadrant and lower two quadrants of entire body drain to venous system via this duct

Question 7

Pelvic girdle

Answer 7

bony pelvis

Question 8

Greater pelvis

Answer 8

ilium
ischium

false pelvis
some abdominal viscera found here

Question 9

Lesser Pelvis

Answer 9

pelvic bone
pelvic cavity

true pelvis. area between pelvic inlet and outlet

Question 10

Answer 10

made up of ilium, ischium, pubis, sacrum, coccyx

Strong and rigid

Question 11

Functions of pelvic girdle

Answer 11

bears weight of upper body
weight transfer from axial to lower appendicular skeleton
muscle attachment
containment and support of viscera
attachment of external genitalia

Question 12

Pelvic inlet

Answer 12

superior pelvic opening. Covers sacrum, illium, pubis
separates greater pelvis and lesser pelvis

Question 13

Pelvic outlet

Answer 13

inferior pelvic opening
formed by ischium and coccyx

Question 14

Spinous processes of sacrum

Answer 14

median crest

Question 15

Sacral hiatus

Answer 15

nerves come through here

Question 16

Answer 16

intermediate crest

Question 17

Transverse processes of sacrum

Answer 17

lateral crest

Question 18

Lumbosacral angle

Answer 18

angle between long axis of lumbar region of vertebral column and sacrum

Question 19

Body weight transferred through…

Answer 19

L5 to base of sacrum (S1)

Question 20

Joints of pelvic girdle

Answer 20

lumbosacral joint
sacro-illiac joint
sacro-coccygeal joint
pubic symphysis

Question 21

Illiolumbar ligament

Answer 21

attach both L4, L5 lumbar vertebrae to iliac crest
strong band of connective tissue
role in stabilization of lumbosacral and sacroiliac joints

Question 22

Anterior sacroiliac ligament

Answer 22

sacrum to ilium
resistance to relative anterior sacral tilt (nutation)

Question 23

Sacrotuberous ligament

Answer 23

sacrum to ischial tuberosity
fan-shaped
role in stabilization of sacroiliac joint
resistance to anterior sacral tilt and rotation of pelvis
passes posterior to sacrospinous ligament

Question 24

Sacrospinous ligament

Answer 24

sacrum to ischial spine
creates greater and lesser foramen
role in stabilization of sacroiliac joint

Question 25

Posterior sacroiliac ligament

Answer 25

attach PSIS with lateral crest of sacrum strong resists posterior sacral tilt

Question 26

Contents of Pelvic cavity

Answer 26

terminal parts of ureters urinary bladder rectum pelvic genital organs blood vessels lymphatics nerves

Question 27

Pelvic diaphragm is made of

Answer 27

levator ani and coccygeaus

Question 28

Thoracic and pelvis movement

Answer 28

Thoracic going down = contracting Pelvis going down = relaxing

Question 29

Pelvic diaphragm is suspended by

Answer 29

pubic symphysis and pubic bones (anterior) ilia (lateral) sacrum and coccyx (post)

Question 30

Pelvic floor is the same thing as

Answer 30

pelvic diaphragm

Question 31

Function of pelvic floor

Answer 31

support of pelvic viscera maintain urinary and fecal continence allow voiding, defecation, sexual activity, childbirth

Question 32

Levator Ani

Answer 32

O: pubis, ischium I: anal canal, coccyx A: support/maintain position

Question 33

Coccygeus

Answer 33

C3, 4, 5...

Answer 34

keeps the diaphragm alive

Question 35

S2, 3, 4

Answer 35

keeps the "p"s off the floor
