|
L1-3
|
|
|
Left crus of diaphragm
|
L1-2
|
|
|
Five arcuate ligaments of the diaphragm
|
median = arches over abdominal aorta
Medials (2) = arching over psoas major muscles Laterals (2) = arching over quadratus lumborum muscles |
|
|
The diaphragm arises from with four embryonic structures?
|
1. septum transversum (central tendon of the diaphragm)
2. pleuroperitoneal membranes (bulk of the diaphragm muscle) 3. paraxial mesoderm (outer rim of diaphragm) 4. Esophageal mesenchyme (right and left crus) |
|
|
Where are lymphatic capillaries absent?
|
CNS
bone marrow epidermis hair nails cornea cartilage |
|
|
What serves a lymphatic function in the CNS?
|
CSF
|
|
|
cardiothoracic lymphatics
|
1. retrocardiac nodes
2. infracardiac nodes 3. thoracic duct |
|
|
Which structures drain into the right lymphatic duct?
|
heart, lungs, liver, right upper limb, head and neck
|
|
|
Where is the thoracic duct located?
|
beginning around L2 and extending to the base of the neck
begins as a confluence of lymphatic trunks but in a number of instances a saccular dilation is formed called the cisterna chyli |
|
|
Three trunks on the right side that drain the lymphatics of the body
|
1. right jugular trunk (drains the right side of the head)
2. right subclavian trunk (drains the right upper limb and superficial tissues from right half of abdominal wall) 3. Right bronchomediastinal trunk (drains the thoracic walls, liver, right lung, bronchi and trachea and right portion of the heart) |
|
|
Attachments of the pelvic diaphragm
|
anterior = pubic symphysis/rami
posterior = coccyx/sacrum lateral = ischial tuberosities/spines |
|
|
nerves that supply the pelvic diaphragm
|
ventral rami of 4th and 5th sacral cord, then S3 and 4 and the inferior rectal from pudendal (S2-4)
|
|
|
Blood supply to the pelvic diaphragm
|
rectal arteries and veins
|
|
|
Lymph drainage from the pelvic diaphragm
|
superficial to deep drainage at inferior mesenteric and hypogastric plexi
|
|
