During contraction of skeletal muscle, which of the following does
not change in length?
A band

H zone, I band = umi-Hiksi (shortens) during contraction
H band
I band
Which of the following histologic characteristics distinguishes a
bronchus within the lung from Primary bronchus?
Irregular plates of hyaline
cartilage
Respiratory Portion of Lungs
BronchIOLE (RESPIRATORY)
Alveoli
The non-ciliated secretory cells which randomly interrupts the ciliated
epithelial lining of the bronchiolar mucosa are known as:
Clara/Club Cell
Cell of origin of respiratory (bronchogenic carcinomas)
ADENOcarcinoma
Ciliated cells
Goblet cells
Cell of origin of respiratory (bronchogenic carcinomas)
SMALL-CELL carcinoma
Kulchitsky cells
(enterochromaffin cells)
Secretes serotonin
Cell of origin of respiratory (bronchogenic carcinomas)
LARGE-CELL UNdifferentiated carcinomas
Basal cell
Macrophages in the lungs
Dust Cells
ALIKABOK!
Where is GASTRIN produced?
ANTRUM

Kerckring! :P
Space between sinus endothelium and hepatocytes?
Space of Disse
Endocrine Functions of Liver
IGF-1 Secretion
Vitamin D activation
Hormone metabolism
Cytokine secretion
Classic Hepatic Lobule (HE-HExagon)
Exocrine Functions of Liver
BILE salts synthesis and secretion
Portal Lobule
Portal PALABAS - EXO - TRIANGLE
Space in between hepatocytes
Bile Canaliculi
Fat-storing cells in the liver
ITO cells or Hepatic Stellate cells
(contained in Space of Disse)
Kuppfer cells close to endothelium
Known as the Rappaport Lobule
Portal Acinus
Blood Flow
Diamond-shaped
Compose the PORTAL TRIAD
HEPATIC artery
PORTAL vein
BILE DUCT
Not central vein, okay?!
Cell component that detoxifies drugs in the liver
SMOOOOOTH endoplastic reticulum
Not lysosome or peroxisome, okay?!
EXOCRINE function of the PANCREAS is carried out by:
Acinar cells
Centroacinar cells
Intercalated ducts
Secrete digestive enzymes
ENDOCRINE function of the PANCREAS is carried out by:
Islets of Langerhans
Alpha: Glucagon
Beta: Insulin
Delta: Somatostatin
Which of the following cells within the glomerulus form the
filtration slits?
PODOCYTES
foot processes
Difference of PCT and DCT histologically
Both are simple CUBOIDAL but PCT has:
BRUSH BORDERS - for greater SURFACE AREA REABSORPTION since majority of solutes are filtered here
PCT (Workhorse of the nephron)
