Anatomy & Embryo Flashcards
From what arterial trunk does the Right Subclavian arise?
brachiocephalic trunk
From what artery does the Left Subclavian arise?
arch of the aorta
What artery does the thyrocervical trunk arise?
subclavian artery
The thyrocervical trunk supplies the inferior thyroid arteries.
What vein unites with the subclavian vein posteriorly to the medial end of the clavicle and forms the brachiocephalic vein?
Internal jugular vein
The union is called the venous angle and is the site where the thoracic duct & right lymphatic trunk drain lymph into the venous circulation.
What does the right recurrent laryngeal nerve loop around?
loops inferior to the right subclavian artery at T1-T2 level
What does the left recurrent laryngeal nerve loop around?
it loops inferior to the arch of the aorta at T4-T5 level
What intrinsic muscle of the larynx is not innervated by the laryngeal recurrent nerves?
cricothyroid muscle
6 branches of the carotid artery: (memory aid “1, 2, 3”
1 medial branch: ascending pharyngeal
2 posterior branches: occipital & posterior auricular
3 anterior branches: superior thyroid, lingual, facial
mesonephros
function as the interim kidneys for 4 weeks until the permanent kidneys develop
form most of the male genital duct system
mesonephric (Wolffian) ducts
form most of the female genital duct system
paramesonephric ducts (Mullerian) form superior vagina, uterus, uterine tubes
metanephros
primordia of the permanent kidney; functions at ~ 9 weeks
embryonic remnant of the gubernaculum in females
round ligament
ligament that carries the ovarian vessels
suspensory
divisions of the broad ligament
mesovarium, mesosalpinx and mesometrium.
