1The four basic layers of the gut:
1. [blank_start]Mucosa[blank_end]
2. [blank_start]Submucosa[blank_end]
3. [blank_start]Musculosa[blank_end]
4. [blank_start]Adventitia[blank_end] / [blank_start]Serosa[blank_end]- AMucosa
- BSubmucosa
- CMusculosa
- DAdventitia
- ESerosa
2[blank_start]Mucosa[blank_end] is the innermost layer lining the lumen. It consists of:
1. [blank_start]Epithelium[blank_end]
2. [blank_start]Lamina propria[blank_end]
3. [blank_start]Muscularis mucosae[blank_end]- AMucosa
- BEpithelium
- CLamina propria
- DMuscularis mucosae
3Muscularis mucosae is a [blank_start]thin[blank_end] layer of [blank_start]smooth muscle fibers[blank_end].
Inner - [blank_start]circular[blank_end]
Outer - [blank_start]longitudinal[blank_end]- Athin
- Bsmooth muscle fibers
- Ccircular
- Dlongitudinal
4Movement of muscularis mucosae is dependent from movements of wall of digestive tract.
- ATrue
- BFalse
5Function of muscularis mucosae:
1. [blank_start]Separate mucosa from submucosa[blank_end]
2. [blank_start]Promote movement of mucosa[blank_end] to [blank_start]increase contact with food[blank_end]- ASeparate mucosa from submucosa
- BPromote movement of mucosa
- Cincrease contact with food
6Submucosa is a layer of [blank_start]dense fibroelastic CT[blank_end] rich in [blank_start]blood[blank_end] and [blank_start]lymph vessel[blank_end].
- Adense fibroelastic CT
- Bblood
- Clymph vessel
7Submucosa may contain:
1. [blank_start]Glands[blank_end]
2. [blank_start]Lymphoid tissue[blank_end]- AGlands
- BLymphoid tissue
8Musculosa consists of [blank_start]spirally arranged[blank_end] [blank_start]smooth muscle fibers[blank_end].
- Aspirally arranged
- Bsmooth muscle fibers
9Musculosa is divided into:
Inner - [blank_start]circular[blank_end]
Outer - [blank_start]longitudinal[blank_end]- Acircular
- Blongitudinal
10Musculosa contraction produces a series of [blank_start]peristaltic waves[blank_end].
- Aperistaltic waves
11Serosa is composed of:
1. [blank_start]Loose connective tissue[blank_end] (traversed by large [blank_start]blood[blank_end] and [blank_start]lymph vessel[blank_end] and [blank_start]nerve trunks[blank_end])
2. A [blank_start]mesothelial[blank_end] covering of [blank_start]simple squamous epithelium[blank_end].- ALoose connective tissue
- Bblood
- Clymph vessel
- Dnerve trunks
- Emesothelial
- Fsimple squamous epithelium
12In places not covered by [blank_start]peritoneum[blank_end], serosa is replaced with [blank_start]adventitia[blank_end] ([blank_start]fibrosa[blank_end]).
- Aperitoneum
- Badventitia
- Cfibrosa
