1
Q

Mesothelium

A

Epithelial tissue that lines body cavities

2
Q

Endothelium

A

Lines heart and blood/lymph vessels

3
Q

Epithelium

A

Lines external and internal body walls and glands

4
Q

Ground substance molecules

A

GAGs:disaccharide repeats can form hyaluronan complexes (biggest contributor to hydrophillic nature of Ground substance)

Proteoglycans: core proteins that tend to aggregate

Multi adhesive glycoproteins: cell attachment and cell signaling sites

5
Q

Surface ectoderm makes what

A

All epithelial tissues of external surfaces.

6
Q

Neural ectoderm makes what?

A

Most nervous tissues

7
Q

Neural tube makes what?

A

CNS features (brain/spinal cord)

8
Q

Neural crest forms what?

A

PNS tissues

9
Q

Endoderm forms what?

A

Epithelial of respiratory, urinary, endocrine and digestive systems

10
Q

Mesoderm forms what?

A

Skeletal and smooth muscle, connective tissues, reproductive tracts

11
Q

Lateral plate forms what?

A

Cardiac muscle, blood, lymph and endothelium parts

12
Q

Action Proteins in cilia

A

Dysin and kinsin form axoneme which allows for cellular movement

13
Q

Terminal bar formed from

A

Tight junctions
Adherens junctions
Desmosomes

14
Q

Gap junctions

A

Provide cellular communication for neighboring cells via connexons

15
Q

Cilia

A

Short extensions at the apical surface of cellular membranes

-motile and mobile

16
Q

Microvilli

A

Short extension at the apical surface. Provide increased surface area and move mucus

  • non motile, but mobile
17
Q

Stereovilli

A

Long extension of cellular membranes. Increase surface area.

  • non motile but mobile
18
Q

Tight junctions

A

Form a functional seal between cells and limits paracellular movement of fluid and solutes.

  • have 3 main proteins (occludins, Claudius and JAM molecules)
19
Q

Adhering junctions

A

Strong physical attachment of cells at the terminal end of lateral surfaces.

20
Q

Desmosomes

A

spot-like attachments between cells found on the lateral surfaces.

21
Q

Pelican

A

Reciprocal folding of lateral walls of adjacent cells that increase surface area.

22
Q

Merocrine

A

Secretory products are released in membrane bound vesicles that fuse to apical surface and conduct executors is of products.

23
Q

Holocrine

A

Secretory product builds up in cells and then is released via apoptosis of the cell

24
Q

Apocrine

A

Secretory product is included within a piece of the plasma membrane envelope and released at the apical domain
