What are cells found in epithelium that secrete mucous?
Cells found in epithelium that secrete mucus are primarily goblet cells. These specialized epithelial cells are scattered throughout various types of epithelial tissues, particularly in the respiratory and intestinal tracts. Goblet cells produce and release mucus, which serves to lubricate and protect surfaces, trap particles, and facilitate the movement of materials. Their presence is crucial for maintaining the health and functionality of these epithelial linings.
What types of cells either form a barrier that controls passage of molecules or forms glands?
Epithelial cells form barriers that control the passage of molecules through tissues and organs. They can also form glandular cells that secrete substances such as hormones or enzymes.
Are goblet cells found in stomach?
No, goblet cells are not typically found in the stomach. They are primarily located in the intestinal lining, where they secrete mucus to protect and lubricate the intestinal tract. In the stomach, the main cell types include parietal cells, chief cells, and mucous neck cells, which secrete gastric acid, digestive enzymes, and mucus, respectively.
What is the functional histology of the digestive tract?
The digestive tract is lined with different types of epithelial cells that perform different functions. For example, columnar cells in the small intestine aid in absorption, while goblet cells secrete mucus for lubrication and protection. Smooth muscle cells in the muscularis layer help propel food along the tract through peristalsis.
Do epithielial tissue form glands?
Yes, epithelial tissues can form glands. Glands are specialized structures made up of epithelial cells that secrete substances to be released into the body or into ducts. There are various types of glands such as exocrine and endocrine glands that are derived from epithelial tissue.

Their presence is crucial for maintaining the health and functionality of these epithelial linings.
What of the tissue types can expect to find goblet cells?
Goblet cells are typically found in the epithelial lining of the respiratory tract, gastrointestinal tract, and conjunctiva of the eye. These cells secrete mucus to protect and lubricate these tissues.
What is the order of cells in the digestive system?
The order of cells in the digestive system can be described in terms of the types of cells involved in digestion. It begins with specialized epithelial cells lining the oral cavity, stomach, and intestines, which secrete enzymes and mucus. Next, gastric and intestinal cells help in the breakdown of food, while absorptive epithelial cells in the intestines facilitate nutrient absorption. Finally, various types of cells in the pancreas and liver contribute to digestion and metabolism by producing digestive enzymes and bile.

What are the types of secretory cells in the stomach and what do they secrete?
Gastric glands which secrete:HClRenninpepsin

How many hormones do the five types of anterior pitiutary cells secrete?
The five types of anterior pituitary cells secrete several hormones. Gonadotroph cells secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH), corticotroph cells secrete adrenocorticotropic hormone (ACTH), lactotroph cells secrete prolactin (PRL), somatotroph cells secrete growth hormone (GH), and thyrotroph cells secrete thyroid-stimulating hormone (TSH).
What is the difference between glandular cells and theca cell?
Glandular cells are specialized epithelial cells that secrete various substances, such as hormones, enzymes, or mucus, depending on their location in the body, like in glands. Theca cells, on the other hand, are specific to the ovarian follicle and play a crucial role in steroid hormone production, particularly androgens, which are converted to estrogens by surrounding granulosa cells. While both types of cells have secretory functions, their specific roles and locations in the body differ significantly.
The salivary glands are composed of which two types of cells?
The two types of cells that make salivary glands areserous cells that secrete watery fluid without mucusmucuous cells that secrete watery fluid with mucuous
What type of epithelial cell?
Squamous , cuboidal , stratified , columnar , pseudostratified are types of epithelial cells .
