Cecum and Appendix

Question 1

lymphatic drainage of the cecum and apprendiz

Answer 1

Lymph from the cecum and appendix ultimately drains into the upper and lower ileocolic lymph nodes, which surround the ileocolic artery.

However, lymph from the cecum travels via a number of intermediate mesenteric nodes, whereas that of the appendix travels via a single intermediate node in the mesoappendix.

Question 2

cecum blood spply

Answer 2

The cecum is derived from the embryologic midgut – and therefore blood is supplied by a branch of the superior mesenteric artery. The branch is the ileocolic artery, which splits into anterior and posterior caecal arteries to supply the cecum.

Question 3

cecum vein drainage

Answer 3

Venous drainage is provided by the ileocolic vein, which empties into the superior mesenteric vein.

Question 4

appendix blood supply

Answer 4

The appendix receives its blood supply via the appendicular artery (derived from the ileocolic artery),

Question 5

appendix veinous drainage

Answer 5

and drains through the appendicular vein.

Question 6

what are both the appendicular artery and vein contained in

Answer 6

within the mesoappendix, a fold of mesentery which suspends the appendix from the terminal ileum.

Question 7

how does the ans supply the cecum and appendix

Answer 7

innervates the cecum and appendix. It achieves this by means of the ileocolic branch of the superior mesenteric plexus, which follows the same course as the ileocolic artery.

Question 8

what is the cecum a reservoir for

Answer 8

chyme

Question 9

what does the appendix contain a large amount of?

Answer 9

a large amount of lymphoid tissue, but has no vital functions in the human.

Question 10

where does the cecum found

Answer 10

is the most proximal part of the large intestine and can be found in the right iliac fossa and suprapubic region. It lies slightly inferior to the iliocaecal junction, and can be palpated in the right iliac fossa if enlarged due to faeces, gas or malignan

Question 11

what are the catogoris o the 7 main locations of the appendixposition of the free end

Answer 11

Pre-ileal – Anterior to the terminal ileum – 1 o’clock.
Post-ileal – Posterior to the terminal ileum – 2 o’clock.
Sub-ileal – Parallel with the terminal ileum – 3 o’clock.
Pelvic – Descending over the pelvic brim – 5 o’clock.
Sub-caecal – Below the cecum – 6 o’clock.
Paracaecal – Alongside the lateral border of the cecum – 10 o’clock.
Retrocaecal – Behind the cecum – 11 o’clock.
