1

where anatomically is the nipple typically found in males

4th intercostal space

2

where anatomically is the nipple typically located in females

5th intercostal space or lower

3

ligament that keeps breasts perky

suspensory ligaments "of Cooper"

4

where does approximately 75% of breast lymphatic drainage go to

apical axillary nodes
pectoral axillary nodes

5

where does approximately 25% of breast lymphatic drainage go to (shared with lungs)

parasternal nodes

6

where does blood supply to the breasts come from

medial and lateral mammary arteries

7

where is the neurovascular plane found in relation to the intercostal muscles

between internal and innermost intercostals

8

what dermatome is associated with the umbilicus?

T10

9

what dermatome is associated with the inguinal canal

L1

10

linea semilunaris

lateral border of the rectus sheath

11

linea semicircularis (arcuate line)

at the end of the rectus sheath

12

inguinal ligament attachments

extends from anterior superior iliac spine to pubic tubercle
forms "floor" of inguinal canal

13

inguinal ligament made from

fused inferior borders of external and internal abdominal obliques

14

Falx inguinalis (conjoint tendon) formed by

fusion of internal abdominal oblique and transverse abdominus

15

falx inguinalis function

reinforces hyopgastric region
extends through spermatic cord as the cremasteric layer

16

lacunar ligament

expansion of the inguinal ligament to the pectineal line of the pubis

17

pectineal ligament

extends laterally from the lacunar ligament along the pectineal line of the pubis

18

fascia transversalis

lies deep to the deep fascia and superficial to the peritoneum

19

hesselbach's triangle boundaries

inguinal ligament
inferior epigastric vessels
linea semilunaris

20

where is the area of weakness in the inguinal region where hernias will most likely present

hesselbach's triangle

21

direct inguinal hernia

most common in both sexes
protrusion directly through the anterior abdominal wall in the area of the superficial inguinal ring

22

indirect inguinal hernia

protrusion follows the course of the inguinal canal where testicle passed through

23

femoral herrnia

more common in females
protrusion through femoral canal
