Detailed Answers (Verified 100%) Already
Graded A+
Cementum
Specialised, calcified connective tissue that covers the
root of a tooth. Soft, permeable and removed by
abrasion. Secreted by cementocytes (in lacunae)
Periodontal ligament
Embeds tooth to jaw. Collagenous Sharpey's fibres
insert into cementum and periosteum of alveolar bone.
,Submandibular glands
Mixed salivary glands (mostly serous)
Sublingual glands
Mixed salivary glands (mostly mucous)
Demilunes
How serous cells in mixed salivary glands appear in
section. Mucous cells displace serous cells and they
become present shapes attached to the acinus.
Myoepithelial cells
Contractile cells lying between PM of epithelial
secretory cells and basal lamina.
,Sections of secretory ducts
Intercalated ducts -> Intralobular (striated) ducts ->
Excretory ducts
Oesophagus mucosa
Stratified squamous epithelium with muscularis mucosa.
Mucous secreting glands in upper and lower parts in
lamina propria or submucosa.
, Muscularis externa of oesophagus
Striated in upper 1/3, mixed in middle 1/3, and smooth
in lower 1/3. Striated to help with swallowing.
Oesophogastric junction
Where epithelium changes from stratified squamous to
simple columnar and lamina propria changes from
loose CT to glandular tissue
Rugae
Longitudinal submucosal folds that allow stomach to
distend when full
Mamillated areas
Grooves in mucosa that allow stomach increased
surface area for secretion.
