|
|
How is the ventral horn of the spinal cord arranged with respect to limb enlargements?
|
alpha motor neurons to trunk and proximal muscles are located medially; ..to distal muscles, laterally; ..to extensors, anteriorly; ..to flexors, posteriorly. (i.e. anterolateral herniation would damage distal extensor muscles of limb)
|

|
|
Example of a fibrocystic change that implies an increased risk for subsequent invasive breast cancer
|
Sclerosing adenosis - a proliferative fibrocystic disease; proliferation of small ducts and myoepithelial cells near the terminal duct lobular unit; fibrosis that distorts the glands and lobules into a whorled pattern.
|
|
|
Examples of benign non-proliferative changes in the breast -- NON-cancerous
|
blue-domed cyst of Bloodgood (dark fluid filled cysts), duct ectasia (associated with periductal inflammation, fibrosis, common in elderly women), apocrine metaplasia (transformation of ductal epithelial cells to eosinophilic cells, to look like apocrine sweat gland epithelium), intraductal papilloma (occurs in subareolar ducts, solitary, middle aged, mimics cancer and associated with nipple discharge)
|
|
|
Cell Marker for NK cells
|
CD16+
|
|
|
Most common breast mass in men, under 25 years of age; presents as painless, firm, mobile mass beneath the nipple without fluid expression

Presentation: low weight infant, short for age, cleft palate, nonspecific rhinitis, widespread desquamating maculopapular rash; positive for antibodies that flocculate mammalian cardiolipin; post-penicillin tx -> Endotoxic Shock (purple ecchymoses, spiking fever, and hypotension)
|
Congenital syphyllis
|
|
|
decrease in change in oncotic pressure indicates an increase or decrease in RBF?
|
Increased RBF
|
|
|
Presentation: Atypical pneumonia due to the overreplication of type II pneumocytes and their production of surfactant-rich exudates, which fill alveolar sacs and cause death by asphyxiation
|
P. jiroveci (EXTRACELLULAR organism; it also causes destruction of type I pneumocytes, but noncontributory to thickening of alveolar septa or interstitial pneumonia)
|
|
|
Symptom: multiple masses located at the gray-white matter junction
|
possibility (almost certainty) of metastatic disease
|
|
|
Where can you find the Great Saphenous Vein?
