5. All of the above are true.
6. Only a + d are true.

3. Smooth Endoplasmic Reticulum:

1. Contains Hydrolytic digestive enzymes.
2. Is present in abundance in the Liver cells.
3. Is present in abundance in the Pancreatic Acinar cells.
4. Contains enzymes of detoxification.
5. Only b + d are true.
6. None of the above is true.

Answer 1

Myoepithelial cells are present in sweat gland

A uterus Is lined by a thick mucosa, the endometrium, surrounded by a thick wall of smooth muscle, the myometrium.

B intestinal epithelium is columnar epithelium

C myoepithelial cell are found in glandular epithelium for example mammary gland,sweat gland

D epithelium.of pancreas Is cuboidal

Answer 2 all are true

Reticular cells Is composed of one or more types of very thin and delicately woven strands of type III collagen and form mesh network in liver bonemarrow and lymphatics system

As collagen combined with fibre so they react with periodic acid Schiff agent and silver stain but not by heamatoxylin

Answer 3 b and d is true

smooth endoplasmic reticulum are reticulum without ribosomes

It synthesis lipid,phospholipid and steroid

It carry out metabolism of carbohydrates and detoxification

The smooth endoplasmic reticulum also contains the enzyme glucose-6-phosphatase, which converts glucose-6-phosphate to glucose, a step in gluconeogenesis

in the liver, the SER contains large amounts of cytochrome P450 and participates in the detoxification of metabolic waste products, drugs, and alcohol; in the muscle,
