PAG02 = DISSECTION

Question 1

What is health and safety for dissection?

Answer 1

take care with sharp instruments
Wear non-latex gloves to protect hands
● Wear goggles to protect eyes from harmful chemicals
● Wear an apron
● Dispose of waste responsibly and safely

Question 2

How do you do an external examination dissection of the kidney?

Answer 2

1. Look at the outside of the kidney – renal capsule​.
2. Beneath the renal capsule is the cortex​.
3. Part of the kidney is indented – this is the renal hilum​.
4. The tubes are the renal vein​, renal artery​ and the ureter​.
5. Draw an annotated scientific diagram of the outside

Question 3

How do you differentiate from the artery, vein and ureter?

Answer 3

The wall of the artery is
thicker than the wall of the vein. The ureter is likely to have the most adipose (fatty)
tissue around it.

Question 4

How do you do an internal examination dissection of the kidney?

Answer 4

Cut the kidney in half lengthways​ from one side. Split it open and have a look at the
structures inside.

Question 5

What structures would you see?

Answer 5

cortex, medulla (renal pyramids), renal columns, renal calyces, renal pelvis

Question 6

How does the cortex appear?

Answer 6

dense and grainy​ and is a lighter shade than the medulla.

Question 7

What are in the medulla?

Answer 7

many cone-shaped structures​ – these are renal

pyramids

Question 8

How do renal pyramids appear?

Answer 8

appear stripy because they contain straight sections of the nephrons
(loops of Henle and collecting ducts).

Question 9

What are in between pyramids?

Answer 9

Renal collumns

Question 10

What are renal calyees?

Answer 10

Hollow cavities may be visible leading from the base of the renal pyramids
These lead to a larger hollow structure called the renal pelvis​, which connects to the
ureter.
