Q

Where does Xiphoid process lie

A

It lies at the apex of subcostal angle

and its apex is sometimes bent forward and hence easily palpable beneath the skin.

16
Q

The midline linear furrow

divides the anterior abdominal wall

A

Right and left halves. It corresponds to Linea Alba

17
Q

What is Umbilicus

A

It is an irregular, depressed scarred area in the linear midline
furrow, a little below its midpoint

18
Q

What is Linea Semilunaris

A

A curved furrow, which extends from tip of the 9th costal cartilage to the pubic tubercle. Lies few centimeters away from the median furrow and corresponds to the lateral margin of the rectus abdominis.

19
Q

Spermatic Cord

A

Soft rounded cord present in the males. Can be palpated through skin as it passes downward just above the medial end of inguinal ligament to enter the scrotum.

20
Q

What is McBurney’s Point

A

A point at the junction of medial 2/3rd and lateral 1/3rd

of the line extending from the umbilicus to the anterior superior iliac spine (spinoumbilical line).

21
Q

What is Murphy’s Point

A

A point where linea semilunaris meets the right

subcostal margin. It corresponds to the tip of the 9th costal cartilage.

22
Q

Transpyloric Plane/Addison’s Plane

A

Imaginary horizontal plane which passes through

the midpoint of the line joining the jugular (suprasternal) notch to the symphysis pubis.

23
Q

Addisons plane lies at

A

Anteriorly : the tip of 9th Costal cartilage

Posteriorly : Lower border of L1 Vertebrae

24
Q

Which plane is the key plane of abdomen:

A

Transpyloric Plane/Addison’s Plane

25
Q

Subcostal Plane

A

An imaginary horizontal plane, which passes immediately below the costal margins.

26
Q

Subcostal Plane lies at

A

Anteriorly : Lower margins of 10th Costal Cartilage

Posteriorly : Body of L3 Vertebrae

27
Q

Transumbilical Plane

A

Imaginary line that passes thru’ Umbilicus

28
Q

Transumbilical Plane lies at the level of

A

Intervertebral disc between L3 AND L4

29
Q

Intertubercular Plane

A

Imaginary line that joins the tubercules of iliac crest

30
Q

Right and Left Vertical Planes are also called as

A

Midclavicular Planes

31
Q

Midclavicular plane

A

They pass from the midpoint of the clavicle superiorly to the point midway between the anterior superior iliac
spine and the pubic symphysis inferiorly, i.e midinguinal
point
