week 11 Flashcards
flank fold is formed by
cutaneous trunci muscle and skin
subiliac lymph nodes recieve afferent lymphatics from
skin of pelvic thigh and leg; and abdomen and caudal portion of thorax
lateral cutaneous femoral nerve is formed from
ventral branches of L3, L4, and possibly L5
EACH SPINAL NERVE IN THE LAS FEW THORACIC AND LFIRST FEW LUMBAR PSINAL REGION DIVIDES into
dorsal and ventral branches
dorsal branches divide into
medial and lateral branches
medial and lateral branches innervate the
epaxial muscles
latearl branches also supply
cuaneous branches of the dorsal branches
cutaneous branches are located between
longissimus lumborum and iliocostalis lumborum
cutanoues branches innervate
abdominal wall from dorsal midline to the level of the patella
ventral spinal nerve runs between
internal abdominal oblique and transversus abdominis
ventral branches supply
muscles of the abdominal wall
tunica flava abdominis function
aids in support of abdominal viscera
fiber direction of external abdominal oblique
dorsal muscle fibers run horizontally; ventral fibers course caudoventrally to the linea alba
internal abdominal oblique muscle fiber direction
cranioventrally (see attachments if needed)
transversus abdoinis attachments in horse
from medial surface of asternal ribs; transverse processes of lumbar vertebrae; xiphoid cratilage; linea alba;
transverus abdominis attachments in ruminants
transverse processes of first 5 lumbar vertebrae; medial surface of asternal ribs; last rib; linea alba
in ruminant, muscular part of transverus addominis is located
more ventrally
right crus of diaphragm attachments
ventral surface of 1st to 4th lumbar vertebrae via ventral longitudinal ligament
left crus of diaphragm attachments
ventral surface of the 1st and 2nd lumbar vertebrae via the ventral longitudinal ligament
spleen courses
obliquely cranioventrally from level of the last 3 or 4 ribs to the ventral third of the 9th-12th ICS
left kidney location
ventral to last rib and first 2 or 4 lumbar transverse processes
left dorsal colon, ingesta travels
cranially
left ventral colon, ingesta travels
caudally
right kidney location
ventral to the last 2 or 3 ribs and the first lumbar transverse processes
right ventral colon ingesta travels
cranially
right dorsal colon ingesta travels
caudally
greater omentum courses
from greater curvature of the stomach and initial part of the duodenum to the terminal part of the large colon and inital part of the small colon
right triangular ligament
right liver lboe and the costal part of the diaphragm
left triangular ligament
courses between the left liver lobe and the central tendon of the diaphragm and should still be intact
coronary ligament
around caudal vena cava
what does the liver contact
stomach; duodenum; diaphragmatic flexure; right dorsal colon; cranial part of the base of the cecum
body of stomach located between
between the saccus cecus and he smaller pyloric region
initial portion of the pyloric region is the
pyloric antrum
what are the parts of the equine small intestine
cranial part of duodenum cranial duodenal flexure descending duodenum caudal duodenal flexure ascending duodenum duodenojejunal flexure jejunum ileum ileocecal orifice
what is the first part of the intestinal tract to have smooth muscl ebands
cecum
contraction of the teniea cause
sacuulations or haustra
what bands does the cecum have
dorsal, ventral, medial, and lateral
dorsal and ventral cecal bands are conssidered
avascular
medial and lateral bands are
vascular
how many tenia does the right ventral colon have
4
left ventral colon has
4
left dorsal colon has
1
right dosal colon has
3
transverse colon has
2
descending colon has
2
parts of the equine large intestine
cecum ascending colon (right ventral colon sternal flexure left ventral colon pelvic flexure left dorsal colon diaphragmatic flexure reight dorsal colon) transverse colon descending colon rectum
which kidney is heart shaped
right
which kidney is bean shaped
left
major splanchnic nerve provides
sympathetic nerve fibers to the adrenal gland and to the celiac and cranial mesenteric ganglia and plexus
dorsal and ventral vagal trunks supply
parasympathetic innervation to the abdominal viscera
adrenal glands receive blood supply from
arteries arising directly from the aorta or from arteries arising directly from the aorta or from arteries arising from the renal arteries
spleen shape in sheep
triangular-shaped
spleen shape in goat
quadrilateral
ruminant small intestine
cranial part of duodenum cranial duodenal flexure descending duodenum caudal duodenal flexure ascending duodenum duodenojejunal felxure jejunum ileum
ruminant large intestine
cecum ascending colon (proximal loop spiral loop centripetal coils, central fleuxre centrifugal coils, distal loop) transverse colon descending colon with sigmoid flexure
