Borders and important elements

Question 1

Borders of the mammary region

Answer 1

1.superior: 3rd rib
2.Inferior: 5th or 7th rib
3.Lateral: Anterior axillary line
4.Medial:STERNAL LINE
5.deep: fascia pectoralis
Layers
1.The skin
2.The adipous conjunctive tissue
3.The mammary gland

Question 2

Mammary region arteries and veins

Answer 2

1. INTernal thoracic
2. lateral thoracic
3. Thoracoromial
4. intercostal

Question 3

Lymphatic system of mammary region

Answer 3

Superficial
1.Papillar plexus
2.Subdermal plexus
Deep
1.main pathway (subpectoral)
2.Auxiliar pathway

Question 4

Anterior wall of Rectus sheath

Answer 4

1.5 apponeurosis
1 External oblique
Anterior layer of internal oblique

Question 5

Posterior wall of Rectus sheath

Answer 5

1.5 apponeurosis
1. Transversus abdominis
Posterior layer (Lamina) of Internal oblique
It disappears at the end of the rectus abdominis

Question 6

In the inferior 1/3rd of the rectus abdominis muscle

what happens to the Rectus sheat?

Answer 6

The posterior layer is replaced by fascia transversalis.
and we will have only anterior layer:
1.trransversus abdomins
2.Internal oblique
3.External oblique

Question 7

Inguinal canal is

1. men
2. women

Answer 7

1.Men
a passage between peritoneal cavity and scrotum
2.Women
a passage between peritoneal cavity and pubis.

Question 8

Walls of the inguinal canal

Answer 8

1. Anterior wall= aponeurosis of the external oblique muscle.
2. Superior wall=Inferior margin of transverse abdominal muscle and Internal oblique muscle
3. Inferior wall=Inguinal ligament and Lacunar ligament
4. posterior wall=Fascia transversalis (weakest wall)

Question 9

The inguinal triangle (Hesselbach) Borders

Answer 9

1.Superior
Inferior margins of Transversus abdominis and internal oblique.
2.Inferior:
1.Inguinal ligament
3.Medial:
Lateral margin of the rectus sheath

Question 10

Inguinal canal in male and female

Answer 10

in male Contains:
SPERMATIC CORD
Ductus defernes and deferens artery and testicular artery and cremasteric artery
Genital branch of the genitofemoral artery
In female:
Round ligament of the uterus
Genital branch of the genitoemroal nerve.
The most important thing to know is
In male:Spermatic cord
in Female: Round ligament of the uterus

Question 11

The spaces(lacunae) is situated

Answer 11

At the base of the thigh

between the anterior margin of the coxal bone and the inguinal ligament.

Posterior: anterior margin of the coxal bone
descend 
1.Ilipopsoas muscle
2.Femoral nerve 
3.lateral cutaneous femoral nerve
