Thalamic Nuclei
|
VPL
--incoming from Spinothalamic (pain & temp) tract and Medial Lemniscus (position, proprioception), ---relays to Somatosensory Cortex (Brodman's areas 1-3) VPM Ventral Posteromedial Nucleus ---incoming from Trigeminal & Gustatory pathways ---relays to same Lateral Geniculate --Relay for Vision Medial Geniculate: relay for audition --input from superior olivary nucleus & inferior colliculus NB: smell not relayed through thalamus |

Thalamic Nucleus Responsible for Audition
input from superior olivary nucleus & inferior output to temporal lobe |

|
|
anatomic landmarks of ureters to bladder
|
start retroperitoneally on top of psoas
pass under gonadal vasculature cross over the common or external illiac arteries (depending on laterality) stay laterl to internal ilac vessels and medial to gonadal vessels before entering uterosacral ligament and gaining access to bladder |
#anatomy #genitourinary
|
|
|
Which heart chamber is closest to the esophagus?
|
left atrium makes up the majority of heart's posterior surface
RA makes up the right border of X-ray LV makes up the left border and paex RV is the front of the heart and inferior border on X ray |
#anatomy #cardiovascular
|
|
|
Pulmonary perfusion
|
Left and Right Bronchial Arteries arise from Descending Aorta.
These perfuse the areas which would not be perfused by simple flow of pulmonary arteries. Majority drains into the Right atrium → RA blood is less oxygenated than blood from pulmonary veins. |

|
|
What part of the testicles are sensitive to heat?
|
The sertoli cells
which are responsible for producing inhibin leydig cells keep chugging thus no lack of sexual dvlpt in cryptorchidism but ↑ risk of testicular cancer |
#anatomy #physiology #endocrine #reproductive
|
|
|
Where do the testicular and adrenal veins drain?
|
Right Adrenal drains via right suprarenal vein directly into IVC
Right Testical Drains directly into IVC Both left Adrenal and Left Testical Drain into Left Renal Vein |
#anatomy #cardiovascular
|
|
|
Nerve Damaged during Thyroidectomy
|
Superior Thyroid Artery & Vein run adjacent to External Branch of Superior Laryngeal nerve, responsible for crichothyroid muscle
|
#anatomy #innervation
|
|
|
Laryngeal innervation
|
Vagus
--recurrent laryngeal nerve ------all laryngeal muscles except cricothyroid ------sensory innervation below vocal cords --Superior Laryngeal NErve ------External Branch: Circothyroid Muscle ------Internal branch: Sensory Innervation above vocal cords NB: Extenral Branch of Superior Laryngeal Nerve runs adjacent to Superior Thyroid Artery/Vein → likely to be damaged in thyroidectomy |

|
|
route of median nerve
|
C6-T1
with brachial artery between biceps brachii and brachialis muscle medial aspect of antecubital fossa crosses between humeral and ulnar heads of pronator teres muscle between flexor digitorum superficialis and flexor digitorum profundus muscles enters hand within flexor retinaculum denervation → thenar atrophy, ape hand deformity lost sensation on palmar surface of first 3.5 digits |
#anatomy #neurology
|
|
|
route of the ulnar nerve
|
between olecranon and medial epicondyle "funnybone" injury
between flexor carpi and flexor digitorum profundus injury paralyses intrinsic muscles of hand → claw hand |

|
|
|
Which strx are associated with which parts of the duodenum (specifically at risk for cancer invasion)
|
1st part: horizontal over L1, only part not retroperitoneal
2nd part: L1-L3 vertical; ampulla of vater 3rd: horizontal along L3 abromainal aorta and IVC close association with uncinate process and SMA/V high risk for invasion 4th superiorly L3 → L2 Ligament of Treitz defines Duodenum from jejunum |
#anatomy
|
|
|
Where is the urethra damaged in a pelvic fx
|
between prostatic urethra and pelvic diaphragm becasue it is firmly attached to both
|
#anatomy
|
|
|
where is the urethra damaged 2° to blunt trauma to perineum w/o pelvic fx
|
blubous urehtra immediately after pelvic diaphragm
|
#anatomy
|
|
|
From whence is saphenous vein harvested for a CABG
|
surgeons access the vein in the femoral triangle just below the pubic tubercle
why? because fuck you that's why. quit asking questions. |
#anatomy #clincial
|
|
|
Artery Damaged with non-displaced crushing fx of femoral neck (eg 2° to osteoporosis)
|
Medial Circumflex Artery supplies majority of blood to the region and is vulnerable as it is closely associated with posterior neck
|
#anatomy
|
|
|
ACL vs PCL
|
ACL:
Tibia anterior midline → Femur Posterior Lateral PCL: Think Straight up and Down on the posterior aspect of both femur and tibia |
