1
Q

Anterior Abdominal Wall

A
  • 3 layers of muscle
  • 3 layers of abdominal fascia
  • 1 muscle between layers
2
Q

Anterior Lateral Muscles

A
  • external oblique

3
Q

Layers of Abdominal Fascia

A
  • aponeurosis of: external and internal oblique, transverse abdominis

  • three layers of abdominal fascia
  • centrally joined to form linea alba

4
Q

Above Arcuate Line

A

5
Q

Below Arcuate Line

A

-all layers of abdominal fascia go anterior to rectus abdomins muscle

6
Q

Inguinal Canal

A
  • parallel and superior to inguinal ligament
  • contains spermatic cord in males and round ligament in females

  • round ligament into labia majora
7
Q

What goes through inguinal canal?

A

8
Q

Cremaster Muscle

A
  • males: from internal oblique, through inguinal canal to testis and spermatic cord

  • females: remnant may be found with round ligament into labia majora
9
Q

Pelvic Floor Muscles

A
  • levator ani group

10
Q

Nerves of Anterior Abdominal Wall

11
Q

Liver

A
  • on right just below diaphragm
  • detoxification of metabolites
  • protein synthesis
  • digestion biochemical
  • gall bladder: inferior to liver, bile storage, breaks down fats
12
Q

Stomach

A
  • esophagus: leads into
  • smooth muscle
  • sphincter at top and bottom
  • exit into small intestine
13
Q

Small Intestine

A
  • 22 feet
  • duodenum
  • jejunum
  • ileum
14
Q

Large Intestine

A
  • ascending
  • transverse
  • descending
  • sigmoid
  • rectum
  • appendix is located right at beginning before it starts ascending
15
Q

Pancreas

A
  • behind stomach

- endocrine gland

16
Q

Kidneys

A
  • bean shaped
  • posterior (back pain)
  • filter blood of waste
  • empty via ureter into bladder
  • urethra
  • renal arteries and veins that come off of aorta and send blood to kidneys to be filtered
17
Q

Sperm Travel

A
  • testicles
  • epididymis (folding part of it-mullet)
  • vas deferens
  • prostate
  • urethra
18
Q

Female External Genitals

A
  • labia majora
  • labia minora
  • clitoris
19
Q

Female Internal Genitals

A
  • vagina
  • cervix
  • uterus
  • fallopian tubes
  • ovaries
20
Q

Cranial Meninges

A
  • dura mater: external, thick, dense fibrous membrane
  • arachnoid mater: intermediate, delicate membrane
  • pia mater: internal delicate membrane
  • CSF: nutrition, cushions brain, gets rid of waste, in subarachnoid space
21
