1) General structure of exocrine gland ---Capsule: CT, which separate the parenchyma into lobules ---lobule:

① acinus: a serous acinus structure pyramidal or cuboidal ③入 round basally-located N apical zymogen granule-acidophilic basal: basophilic-RER, ribosome function: secret salivary amylase(淀粉酶)

① acinus: a. serous acinus: structure: • pyramidal or cuboidal • round basally-located N • apical: zymogen granule-acidophilic • basal: basophilic-RER, ribosome function: secret salivary amylase（淀粉酶）

b. mucous acinus structure pale-stained, slight-blue, flattened n against the basal membrane mucinogen granule Golgi, RER, mitochondria

b. mucous acinus: structure: • pale-stained, slight-blue, flattened N against the basal membrane • mucinogen granule • Golgi, RER, mitochondria

c. mixed acinus: several serous cell attached to mucous acinus serous demilune

c. mixed acinus: several serous cell attached to mucous acinus – serous demilune
