Columnar cells near goblet cells
Mucus in the lumen of the gland
Esophagus
M (red) - mucosa
SM - submucosa
M (black) - muscularis
A - adventitia
Esophagus
E - stratified squamous epithelium of the mucosa
LP - lamina propria with scattered lymphocytes
MM - smooth muscle strands of the muscularis mucosae
Esophagus
SS - stratified squamous epithelium of the mucosa
LP - lamina propria with scattered lymphocytes
MM - smooth muscle strands of the muscularis mucosae
GL - esophogeal mucous gland in the submucosa
D - duct
Esophagus muscularis
St - skeletal or striated muscle fibers
Sm - smooth muscle fibers
Both are seen so this is the middle 1/3 of the esophagus

Loose CT and dense irregular CT
L - loose CT
D - dense irregular CT
Dense irregular CT
Dense irregular CT
Capsule formed by the tissue is seen and covered by a simple epithelium of serous mesothelial cells (S), which produce a hyaluronate-rich lubricant around such organs as the testes
