anatomy general Flashcards
what is the incus/malleus suspended from/by in the tympanic cavity
suspended from tegmen tympani by ligaments
what type of joints connect the bones in the tympanic cavity
synovial joints
what does the otic capsule refer to
dense bone of the petrous temporal bone that surrounds the membranous labrynth of the inner ear
(aka the osseous labrynth/ bony labrynth)
what muscles play a role in accoustic reflex
(accoustic reflex describes what the reaction of the ear drum to a loud sound)
stapedius and tensor tympani muscle
nasopharynx/oropharynx innervation, also innervates…
CN IX
(glossopharyngeal nerve)
middle ear! good example of referred pain eg tonsilitis causes otalgia
Laryngopharynx innervation
CN X
Wht veretbral level does spinal cord end
L2
What vertebral level does the subarachnoid space end
S2
What vertebral level do u take csf fluid
L4
what node drains the palatine tonsil
jugulo-digastric node found in the neck
where does lymph from the scrotum/most of the penis (not the glands) drain
b) where are these nodes found
superficial linguinal nodes
b) found in the superficial fascia of the groin
where does lymph from the testis drain into
lateral aortic and pre-aortic lymph nodes
where does the lymph from the kidneys drain into
the lumbar nodes
where does lymph from the ureters drain into
lumbar nodes and the illiac nodes
where does lymph from the superficial inguinal drain
mostly directly into the external illiac nodes and some to the deep inguinal nodes
describe the route of the superficial lymph nodes of the lower limb
follows saphenous veins> drains into superficial lymph nodes> some deep inguinal lymph nodes but mostly drains directly into the external illiac nodes
where do the deep lymphatics of the lower limbs drain into
popliteal lymph nodes> superficial inguinal nodes
where do the deep lymphatics of the upper limb drain
axillary lymph nodes (which drain into the subclavian nodes)
where do the thyroid veins drain
superior and middle drain into the internal jugular veins
inferior thyroid vein drains into the left bracioceohalic vein
where does the upper thyroid lymph drain into
superior deep cervicaly lymph nodes or the prelaryngeal nodes (which then drain into superior deep cervical lymph nodes)
inferior thyroid lymph drainage
inferior deep cervical lymph nodes
