Flashcards in Histology Deck (18):
1

Fungiform Papilla

Shaped like mushrooms; taste buds found on apical surface

2

Circumvallate Papilla

Large taste buds characterized by Von Ebner's glands

3

Lingual Glands

Small glands inferior to the tongue that contain both mucous and serous glands

4

Parotid Glands

Contain only serous secreting cells

5

Striated Ducts

Part of the intralobular ducts that infoldings of cell membrane lined by mitochondria producing the striated appearance

6

Mucosa

Consists of epithelium, lamina propria, and muscularis mucosa

7

Submucosa

Contains Meissner's plexus to control motility of the intestines

8

Muscularis Externa

Contains Auerbach's plexus; has an inner circular and outer longitudinal layer

9

Esophogeal-gastric jnxn

Will see goblet cells, gastric pits, and change in epithelia to columnar

10

Filliform Papilla

Found all over tongue; show partial keratinization @ the tip

11

Paneth Cells

Eosinophilic cells found in the jejunum that secrete lysozome to control the intestinal flora

12

Plicae Circulares

Permanent spiral folds in the SI were most absorption takes place

13

Brunner's Glands

Characterizing cells of the duodenum that are found in the submucosa; release their secretions at the base of intestinal glands

*large, tubuloacinar, and branched

14

APUD cells

Take up amines and secrete GIP, secretin, and CCK

15

M-Cells

Specialized cells that cover Peyer's in the ileum patches that fnxn to phagocytize luminal Ags and present them to lymphs in the lamina propria

16

Kupffer cells

Macrophages of the liver

17

Sinusoids

Torturous blood channels lined by fenestrated endothelial cells

-Separated from the hepatocytes by the perisinusoidal space

18

Gallbladder histology

Irregular mucosal folds are present along w/ randomly oriented smooth muscle fibers in the muscularis externa

*Adventitia=area in the serosa where the gall bladder contacts the liver
