fundus blood supply
short gastric
what is meckels diverticulum?
embryonic remnant of attachment of midgut loop to yolk sac. approx 1m from ileum end

spleen vasculature
splenic artery (CT) and splenic vein
spleen innervation
coeliac plexus
gut sections and general vasculature and innveration
foregut, oesophagus to major duodenal papilla (coliac axis and greater S)
midgut, MDP to 2/3rd way along transverse colon (SMA, lesser S)
hindgut, distal 1/3rd transverse colon to upper part of anal canal (IMA and least S)

prostate gland vasculature and innervation
prostatic arteries and venous plexus
inferior hypogastric plexus (sympathetic, parasympathetic and sensory)
scrotum vasculature and innervation
anterior and posterior scrotal arteries. Scrotal veins
genitofemoral branch, anterior and posterior scrotal nerves
describe lymph drainage of mammary glands
axillary nodes (75%) parasternal nodes (20%) posterior intercostal nodes (5%)
which nerves supply mammary glands
4th-6th intercostals
what goes through hilum of lung?
bronchus pulmonary artery 2 pulmonary veins bronchial vessels pulmonary plexus of nerves and lymphatic vessels
describe innervation of larynx
recurrent laryngeal supplies motor to all muscles except cricopharyngeal which is supplied by external superior laryngeal. Internal superior laryngeal supplies sensation to larynx.
describe sinus drainage
all sinuses drain into middle meatus except sphenoid which drains into spheno-ethmoidal recess
what drains into the inferior meatus
lacrimal ducts and eustuchian tube
which structures pass through diaphragm and where
IVF and right phrenic T8
Oesophagus and vagus T10
Aorta, zygous vein and thoracic duct T12
what makes the upper oesophageal sphincter?
cricopharyngeus
what info travels through the cerebellar peduncles?
superior (purkinji) inhibition output to pons midbrain and cerebrum
middle, pons telling cerebellum what voluntary movements are happening
inferior, proprioception, balance info
carotid sheath contents
common and internal carotid artery, IJV, vagus
what are the infrahyoid muscles
- sternohyoid (C1-C3)
- omohyoid (C1-C3)
- thyrohyoid (C1)
- sternothyroid (C1-C3)
- all depress hyoid
what are the suprahyoid muscles?
- stylohyoid (mandibular branch of facial)
- mylohyoid (CN Vi)
what is the contents of anterior triangle of neck
common carotid
internal and external carotids
IJV
CN VII, IX, X, XI, XII
what are the spinal roots of the splanchnic nerves
greater T5-T9
lesser T10-T11
least T12
describe innervation of pharyngeal muscles
all constrictors, palatopharyngeus and salpingopharyngeus by vagus. Stylopharyngeus by glossopharyngeal.
uterus ligaments
broad, maintains position
round, maintain anterverted position
ovarian, joins ovaries to uterus
bladder vasculature
internal iliac artery branch, vesicle venous plexus
ureter vasculature
abdominal- renal and testicular/ovarian artery
pelvic- superior and inferior vesical arteries
knee joints
- tibiofemoral (medial and lateral condyles of femur), weightbearing
- patellofemoral (anterior and distal part of femur), allows quadriceps femoris to be inserted directly over the knee
- both lined with hyaline cartilage
knee ligaments
1) patellar
2) collateral
- medial, makes up joint capsule
- lateral
3) cruciate, 2 which cross over eachother
- anterior, prevents anterior dislocation of tibia onto femur
- posterior, prevents posterior dislocation of tibia onto femur
menisci function
- deepen articular surface of tibia to increase stability
- shock absorbers
- when ACL is taut your lateral menisci rotates
which muscles does the median nerve innervate in the hand
LLOAF Lateral Lumbricals Opponens Pollicis Abductor pollicis brevis Flexor pollicis brevis
joints of ankle
tibiotalar - dorsiflexion and plantarflexion
subtalar (talus and calcaneus) - inversion and eversion
what does the sciatic nerve divide into?
tibial common perineal (further divides into deep and superficial)
which nerves supply the thigh compartments
posterior - sciatic
medial - obturator
anterior - femoral
which nerves supply the leg compartments
posterior - tibial
lateral - superficial perineal
anterior - deep perineal
general innervation of arm
anterior - musculocutaneous
posterior - radial
general innervation of forearm
anterior - median
posterior - radial
general action of lower limb
glutes - extend and abduct hip and femur
ant. thigh - flex femur at hip
med thigh- adduct femur
post thigh - extend hip and flex knee
post leg - plantar flexion, flex toes, invert foot
lat leg - evert foot
ant leg - dorsiflexion, entend toes invert foot
