Interval 1

Question 1

pubic tubercle

Answer 1

The inguinal ligament attaches to this inferiorly. It is a prominent, forward-projecting bony prominence on the pubis.

Question 2

pubic crest

Answer 2

A bony area medial to the pubic tubercle which extends from the process to the medial end of the bone.

Question 3

external oblique muscles

Answer 3

Originates at the external surface of the lower eight ribs and inserts into the iliac crest, iliac spine, pubic tubercle, and linear alba. Acts to compress the abdomen and helps w/ forced expiration.

Question 4

internal oblique muscles

Answer 4

think “hands crossed”. Copmresses abdomen and helps w/ forced expiration.

Question 5

transversus abdominus

Answer 5

muscle that is deep to the internal obliques. It helps to compress the abdomen and depress the ribs

Question 6

rectus sheath

Answer 6

The connective tissue formed by aponeuroses of the transversus abdominis and the external and internal oblique muscles. It encloses the rectus abdominis.

Question 7

conjoint tendon (aka inguinal falx)

Answer 7

A structure formed from the lower part of the transversus abdominis muscle as it inserts into the crest of the pubis and serves as the medial part of the posterior wall of the inguinal canal. It protects a weak point in the abdominal wall, and if weak it can precipitate a direct inguinal hernia.

Question 8

linea alba

Answer 8

A tendinous median raphe between the two rectus abdominis muscles extending from the xiphoid process to the pubic symphysis. It is formed by the fusion of the aponeuroses of the external oblique, internal oblique, and transverse muscles of the abdomen.

Question 9

arcuate line

Answer 9

A horizontal line that demarcates the lower limit of the posterior layer of the rectus sheath, where the inferior epigastric vessels perforate the rectus abdominis. IT is normally about 1/3 of the distance from the umbilicus to the pubic crest.

Question 10

the organ that produces milk in females

Answer 10

mammary glands

Question 11

parts of the rib

Answer 11

head, neck, tubercle, angle, shaft (or body), costal grove

Question 12

coronoid process

Answer 12

the small hook-like structure on the lateral edge of the superior anterior portion of the scapula

Question 13

deltoid muscle

Answer 13

the muscle forming the rounded contour of the shoulder

Question 14

inferior epigrastric artery and vein

Answer 14

blood vessels that arise from the external iliac artery above the inguinal ligament, then curve forward in the subperitoneal tissue and pierce the trasnversalis fascia, forming the superolateral border of Hesselbach’s triangle.

Question 15

manubrium

Answer 15

the most superior part of the sternum

Question 16

long thoracic nerve

Answer 16

the nerve that supplies the serratus anterior muscle
