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
