Anterior body walls Flashcards
Where is the breast located
The lateral border of the sternum to mid axillary line. Between 2nd and 6th costal cartilages.
What is the innervation of the breast
T4 innervation, spinal cord emergence at nipple
What is the innervation of the umbilicus
T10 innervation by thoracic spinal nerve
Which end of the rob connects to sternum and which end connects to the vertebra
head connects to the vertebra (posterior), sternal end connects to sternum via costal cartilage (anterior)
Name the different parts of the rib (posterior to anterior)
head, neck, tubercle, angle, internal surface, costal groove, external surface, sternal end, costal cartilage
Name the different parts of a vertebra
vertebral foramen, vertebral body, transverse process, spinous process
What are the anterior features of the pelvis
ilium, pubis, ischium, pubic symphysis, pubic tubercle, anterior superior iliac spine
What is the pubic symphysis
cartilaginous joint (right and left articulate)
What us the pelvic brim
bony aid that surrounds pelvic inlet (there is no separation between pelvic cavity and abdomen cavity
How is the pelvic brim different in men and women
In females the pelvic brim is wide, oval. In men it is narrow, heart shaped.
What forms the pubic arch
formed by inferior pubic ramus of the ischium and pubis.
How is the pubic arch different in men and women
In women it is an oval shape and has an angle of ~ 80 degrees. In men, it is V-shaped and has an angle of < 70 degrees.
How is the obturator foramen different in men and women
In women, the obturator foramen is oval but in men it is more round.
What is the acetabulum
a socket to form hip joint
How is the acetabulum different in men and women
In women it is oval and in men it is round.
What is the superior aspect of the abdominal cavity
5th/6th costal cartilage
What is the function f the intra-abdominal viscera
assists in ventilation, facilitates evacuation (high pressure), movement of the trunk and thoracolumbar spine.
What is the midinguinal point
midpoint of the imaginary line that joins the anterior superior iliac spine and the pubic symphysis.
What are the 2 planes that form the 4 quadrants
median plane and transumbilical plane
What are the 4 planes that form the 9 region
2 x midclavicular planes, subcostal plane and transtubercular plane
What are the 4 quadrants
right upper quadrant, left upper quadrant, right lower quadrant, left lower quadrant
What are the 9 regions (from left to right, up to down)
right hypochondriac region, epigastric region, left hypochondriac region, right lumbar region, umbilical region, left lumbar region, right inguinal region, pubic region, left inguinal region.
Where are the thoraco-abdominal nerves arising from
T7-T11
Where does the subcostal nerve run from
T12
Where does the iliohypogastric nerve arise from
Top of L1
Where does the ilio-inguinal nerve arise from
Bottom of L1
What is the organisation if the anterolateral abdominal wall from superficial to deep
skin, Camper’s fascia, Scarpa’s fascia, external oblique, deep fascia, internal oblique, deep fascia, transverse abdominal muscle, extraperitoneal fate, parietal peritoneum
