Question 1

What are the two types of intercostal Veins

Answer 1

Anterior intercostal
veins
Posterior intercostal
veins

Question 2

WHat do the Posterior intercostal
veins supply?

Answer 2

to azygos or
hemiazygos veins

(bc hemi engines make a load roar from posterior (exhaust) and vein bc it releases CO2)

Question 3

WHat do the anterior intercostal
veins supply?

Answer 3

internal
thoracic or musculophrenic veins (same as arteries)

Question 4

What are the two major lymphatic vessels that recive lymph from all over the body?

Answer 4

Thoracic duct

Right lymphatic duct

Question 5

Where do the right lymphatic and thoracic ducts drain into?

Answer 5

Right; The junction where the right subclavian and right internal juglar veins meet.

Thoracic; The junction where the Left subclavian and Left internal juglar veins meet.

(veins bc it takes them from tissues, so the oxyen is already emptyed)

Question 6

How does the thoracic duct begin? what is that begining called?
What major structure does it pass through?

Answer 6

Begins: As a dilated sac called the cisterna chyle

Pass through: aortic opening

Question 7

Where does the thoracic duct enter the thorax? Where and how does it ascend? Where does it join the blood vascular system?

Answer 7

Enter: In the posterior mediastenium (right of the aorta) (bc it passes behind the heart, so posterior)

Ascend: posterior and left to the esophagus (makes sense bc it is smaller so it will be behind it)

Join: left venous angle (makes sense that is venous bc of the fact that it is lymph)

Question 8

What are the tributaries of the thoracic duct at the root of the neck?

Answer 8

Left jugular vein

Left subclavian vein

Left bronchomediastinal trunk

(bc when are giving someone a tribute you are going to juggle as a celebration)

(ford made a tributary to the brand by bringing the broncho back mediastanial bc it is close to it)

Question 9

Do the anterior primary rami of the thoracic spinal nerves form plexuses?

Answer 9

No, they do not form plexuses but instead come out individually as intercostal nerves.

Question 10

What is the anterior primary ramus of T12 called?

Answer 10

Subcostal nerve (bc it is under the 12th rib where no intercostal space exists)

Question 11

What does each intercostal nerve supply? (skin and muscle)

Answer 11

Skin: Dermatomes

Muscles: Myotome

Question 12

What is the dermatomal distribution of the nipple area? (what spine segment)

Answer 12

From T4

Question 13

What do the Gray and white rami communicantes do in relation to intercostal nerves?

Answer 13

Connect the intercostal nerves to the sympathetic trunk
