Flashcards in Exam 4 Deck (34):
1

Anterior Abdominal Wall

-3 layers of muscle
-3 layers of abdominal fascia
-1 muscle between layers

2

Anterior Lateral Muscles

-external oblique
-internal oblique
-transverse abdominis
-upper 3 all insert into abdominal fascia
-rectus abdominis: between layers of abdominal fascia

3

Layers of Abdominal Fascia

-aponeurosis of: external and internal oblique, transverse abdominis
-join centrally between 2 rectus abdominis muscles to form linea alba (where they crisscross)
-three layers of abdominal fascia
-centrally joined to form linea alba
-arcuate line: approximately 1/2 way between umbilicus and pubic bone

4

Above Arcuate Line

-external oblique aponeurosis is anterior to rectus abdominis
-internal oblique aponeurosis split with half anterior to rectus abdominis and half behind
-transverse abdominis aponeurosis is behind rectus abdominis

5

Below Arcuate Line

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

6

Inguinal Canal

-parallel and superior to inguinal ligament
-contains spermatic cord in males and round ligament in females
-cremaster muscle, testicular artery and vein, ilioinguinal nerve, fascia through inguinal ring into scrotum, and genito femoral nerve
-round ligament into labia majora

7

What goes through inguinal canal?

-spermatic cord, testicular artery and vein, Ilioinguinal nerve, cremaster muscle, genitofemoral nerve go through canal

8

Cremaster Muscle

-males: from internal oblique, through inguinal canal to testis and spermatic cord
-raise or lower testis for temperature control (sperm production) and during sexual arousal
-females: remnant may be found with round ligament into labia majora

9

Pelvic Floor Muscles

-levator ani group
-puborectalis: form a sling from pubic bone, around rectum to pubic bone
-iliococcygeus: ischium to coccyx
-pubococcygeus: pubic bone to coccyx

10

Nerves of Anterior Abdominal Wall

-ilioinguinal: L1, skin of scrotum/labia majora, adjacent medial thigh
-genitofemoral: skin over femoral triangle and scrotum/labia major, cremaster muscle

11

Liver

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

12

Stomach

-esophagus: leads into
-smooth muscle
-sphincter at top and bottom
-exit into small intestine

13

Small Intestine

-22 feet
-duodenum
-jejunum
-ileum

14

Large Intestine

-ascending
-transverse
-descending
-sigmoid
-rectum
-appendix is located right at beginning before it starts ascending

15

Pancreas

-behind stomach
-endocrine gland

16

Kidneys

-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

Sperm Travel

-testicles
-epididymis (folding part of it-mullet)
-vas deferens
-prostate
-urethra

18

Female External Genitals

-labia majora
-labia minora
-clitoris

19

Female Internal Genitals

-vagina
-cervix
-uterus
-fallopian tubes
-ovaries

20

Cranial Meninges

-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

Parts of Brain

-cerebrum: R&L hemispheres; emotions, hearing, vision, voluntary movement, sensory processing, speech
-cerebellum
-brainstem

22

Lobes of Cerebrum

-occipital
-frontal
-parietal
-temporal
-insular

23

Frontal Lobes

24

Parietal Lobe

-primary sensory cortex

26

Occipital Lobe

-visual processing

27

Blood Supply to Brain

-internal carotid artery
-basilar artery: from vertebral arteries
-anterior communicating and posterior communicating to form circle of willis

28

Cerebellum

-two hemispheres
-dorsal to midbrain
