latissimus medially, EO laterally, iliac crest inferiorly
Inferior or Petit triangle
12th rib superiotly, quadratus lumborum medially, IO laterally, floor is transversalis muscle
Superior or Grynfeltt triangle
Trapezius blood supply
Transverse cervical art
internal iliac artery and passes through the greater sciatic foramen. At approxi-mately 6 cm below the PSIS and 4–5 cm lateral to the sacral midline, the artery passes between the gluteus medius and piriformis muscle to enter the gluteus maximus
superior gluteal artery
arises from the internal iliac artery. It passes through the lesser sciatic foramen, inferior to the piriformis muscle, to supply the lower gluteal skin and soft tissue
inferior gluteal artery
quadrangular space of the axilla.
teres major inferiorly, teres minor and subscapularis superiorly, the long head of triceps medially, and the surgical neck of the humeru
originates lateral to the costal cartilage of ribs 2–5 and inserts as the coracoid process of the scapula.
pec minor
begins as the subclavian artery passes out of the chest past the first rib and ends as it enters the arm passing the teres major, becoming the brachial arter
axillary art
below and lateral to the pectoralis major on the anterolateral aspect of the thorax. It originates on ribs 1–9 and inserts on the anterior surface of the medial border of the scapula. Its action is to protract and superiorly rotate the scapula, holding it against the chest wal
serratus anterior
originates from the external surface of the lower eight ribs and inserts into the linea alba, pubic tubercle, and iliac crest.
external oblique
originates at the thoracolumbar fascia, iliac crest, and lateral half of inguinal ligament. It inserts at the inferior border of ribs 10–12, the linea alba, and the pubis
internal oblique
originates from the internal surface of costal cartilage ribs 7–12, thoracolumbar fascia, iliac crest, and lateral third inguinal ligament. It inserts at the linea alba, pubic crest, and pectin pubis.
tranversus abdominis
At the level of the umbilicus there are anastomotic connections to the superior epigastric artery, which is a continuation of the internal mammary artery in the chest
TRUE
The deep circumflex iliac artery (DCIA) originates from the external iliac artery near the origin of the DIEA.
TRUE
superficial inferior epigastric artery (SIEA) is a branch of the proximal femoral artery arising 4-5cm below the inguinal ligamen
false 2-3cm
deep superficial fascia of the perineum is referred to as Colles fascia and is the peri-neal extension of Scarpa’s fascia
TRUE
female perineum are the deep external pudendal artery supplying the anterior labial structures and the internal pudendal artery supplying the clitoris and posterior labial structures
TRUE
The internal pudendal artery continues anteriorly within the deep perineal space to become the dorsal artery of the clitoris
TRUE
superficial perineal nerve, a branch of the pudendal nerve, supplies the posterior two-thirds of the labia, and the terminal branch of the puden-dal nerve becomes the dorsal nerve to the clitoris
TRUE
muscle originates at the inferior internal oblique muscle, inguinal ligament, pubic tubercle, and pubic crest. It inserts into the investing fascia of the sper-matic cord and testes. Its function is to retract the testicles. It is innervated by the genital branch of the genitofemoral nerve.5
