renal, endo and histo Flashcards
describe the order of vessels entering the kidney
renal vein, Renal artery, renal pelvis
coverings of the kidney
perinephric fat surrounds the kidneys and suprarenal glands. This is then encased is a renal fascia. External to this is the paranephric fat.
renal arteries arise at
L1/L2
which renal artery is longer?
right as it passes posterior to the IVC
which renal vein is longer
left, passes anterior to the aorta
location of the kidneys
T12-L3
peritoneal covering of the kidney
retroperitoneal
anterior relations of left kidney
stomach, spleen, jejunum and ascending colon
anterior relations of right kidney
liver, duodenum, ascending colon
posterior relations of the kidneys
quadratus lumborum, subcostal nerve, iliohypogastric and ilioinguinal nerves
peritoneal covering of the ureter
retroperitoneal
constrictions of the ureter
constrictions; junction of the ureters and renal pelves, ureter cross the brim of the pelvic inlet over the external iliac artery, and as it passes through the wall of the urinary bladder.
trigone relations
angles are the ureteric orifices and internal urethral orifice.
walls of the bladder consist of
detrusor muscle
thyroid level
C5-T1
thyroid is connected to what?
cricoid cartilage by a dense fibrous capsule
superior thyroid artery arises from
external carotid
inferior thyroid artery arises from
thyrocervical trunk of subclavian
superior and middle thyroid veins drain into
IJV
inferior thyroid vein drains into
brachiocephalic
innervation of parathyroid and thyroid
cervical sympathetic ganglion
coverings of the supra renal glands
encased in connective tissue and considerable perinephric fat and enclosed by renal fascia attaching them to the crura of the diaphragm.
superior suprarenal artery arises from
inferior phrenic artery
middle suprarenal artery arises from
abdominal aorta near SMA origin
inferior suprarenal artery originates from
renal artery
short right suprarenal vein drains into the
IVC
longer left suprarenal vein drains into the
left renal vein with the inferior phrenic
pancreas peritoneal covering
retroperitoneal
pancreas arterial supply
splenic
pancreas venous drainage
feed into the splenic and superior mesenteric vein into the hepatic portal vein. dominant is the splenic though.
location of the pituitary
suspended form the underside of the brain by the “pituitary stalk”, or the infundibulum. Sits within the sphenoid bone part called the sella turcica.
pituitary anterior lobe parts
pars anterior – largest part
pars intermedia – thin epithelial layer separating anterior form posterior
pars tuberalis – upwards extension of pars anterior
anterior pituitary lobe communicated with the hypothalamus how
anterior lobe communicates with the hypothalamus via the hypophyseal portal vessels
posterior pituitary lobe communicated with the hypothalamus how
magnocellular neurones originating in the supraoptic and paraventricular nuclei of the hypothalamus.
anterior pituitary lobe arterial supply
superior hypophyseal vessel from the internal carotid
posterior pituitary lobe arterial supply
superior hypophyseal artery, infundibular artery and hypophyseal inferior artery
layers of a blood vessel histo
tunica intima
tunica media
tunica adventitia
2 types of arteries
muscular and elastic
layers of the skin
Basal layer stratum Spinosum Stratum Granulosum Stratum lucidum stratum corneum
what is found in the spinosum layer
langerhans cells and keratinocytes
filiform papillae
common, appear white. are keratinized. thread like
fungiform papillae
mushroom like. not keratinised. highly vascular
circumvallate papillae
largest, taste buds.
most dominant layer in the oesophagus
adventitia
most dominant layer in the stomach
muscular external
duodenum most dominant layer
submucosa/musclaris externa
jejunum dominant layer
submucosa
colon dominant layer
muscularis externa
are there parietal cells in the pyloric region
no
ileum distinguishing features
many peyer’s patches, large muscularis externa and little to no plicae
epithelium of the colon
simple columnar mucous absorptive cells
submandibular gland secretions
serous and mucous mixed
sublingual secretions
mucous
parotid secretions
serous
gallbladder is lined with
simple columnar epithelium
type 2 pneumocytes secrete
surfactant
proximal convoluted tubule is coated in
simple cubodial epithelium
thin portions of the loop of Henel is coated in simple squmous epithelium
in simple squamous epithelium
ureter is coated in
stratiifed transitional epithelium
layer’s of the eye
epithelium stratified squamous, Bowman’s membrane, Stroma, Descemet’s layer, endothelium
vocal cord epithelial lining
stratified squamous
epithelium of the oral mucosa
stratified non-keratinizng sqamous epithelium
