Answer 5

inferior gluteal artery

Question 6

quadrangular space of the axilla.

Answer 6

Question 7

originates lateral to the costal cartilage of ribs 2–5 and inserts as the coracoid process of the scapula.

Answer 7

pec minor

Question 8

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

Answer 8

axillary art

Question 9

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

Answer 9

serratus anterior

Question 10

originates from the external surface of the lower eight ribs and inserts into the linea alba, pubic tubercle, and iliac crest.

Answer 10

external oblique

Question 11

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

Answer 11

internal oblique

Question 12

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.

Answer 12

tranversus abdominis

Question 13

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

Answer 13

TRUE

Question 14

Answer 14

TRUE

Question 15

superficial inferior epigastric artery (SIEA) is a branch of the proximal femoral artery arising 4-5cm below the inguinal ligamen

Answer 15

false 2-3cm

Question 16

deep superficial fascia of the perineum is referred to as Colles fascia and is the peri-neal extension of Scarpa’s fascia

Answer 16

TRUE

Question 17

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

Answer 17

TRUE

Question 18

The internal pudendal artery continues anteriorly within the deep perineal space to become the dorsal artery of the clitoris

Answer 18

TRUE

Question 19

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

Answer 19

TRUE

Question 20

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
