Question | Answer |
---|---|
3 layers of Mucus layer | Epithelial lining Lamina Propria Muscularis Mucosa |
Nature of cells of epithelial lining in 1) Mouth to Oesophagus 2) Stomach to LI | Stratified Squamous Cuboidal |
Lamina Propria is made of | Connective Tissue |
Submucus is absent in | Mouth and Pharynx |
Location of Only skeletal muscles in GI Only smooth muscles in GI Both skeletal and smooth muscles in GI | Lips, cheek, wall of pharynx. Stomach and intestine. Esophagus. |
Muscles in Stomach | Oblique Circular Longitudinal |
Muscles of intestine | Circular Longitudinal |
Auerbach's nerve plexus | B/w circular and longitudinal Muscles of Intestine |
Where serosa is replaced by fibrosa? Difference b/w both | Pharynx and esophagus. Serosa has Connective Tissue (CT) and Mesoepithilial Fibrosa has only CT |
Enteric Nervous System is made by | Intrinsic Nervous System |
Functions of entertic nervous system | Movements and secretions of GI |
Enteric Nervous System makes | Auerbach's and Meissner's plexus |
Other name of Auerbach's plexus | Myenteric Plexus |
Receptors in GI tract | Stretch and chemo |
Enteric Nervous System is controlled by | Extrinsic nerves |
Auerbach's plexus and Meissner's plexus are connected to CNS by | Sympathetic and parasympathetic nerves |
