Where is the nucleus of a mucous membrane found?
The nucleus of a mucous membrane is found within the cells that make up the mucosa layer. These cells are typically epithelial cells, which line the surface of the mucous membrane and protect underlying tissues.
Which membrane is adapted for absorbtion and secretion?
The gastrointestinal (GI) mucosa is adapted for absorption and secretion due to its large surface area lined with specialized cells like enterocytes, goblet cells, and enteroendocrine cells. These cells facilitate the absorption of nutrients and water while secreting enzymes, mucus, and hormones for digestive processes.
What is endicytosis?
Endocytosis is a cellular process in which cells absorb molecules or particles by engulfing them into the cell membrane and forming vesicles. It is a key mechanism for nutrient uptake, receptor recycling, and maintaining membrane homeostasis in cells. There are different types of endocytosis, such as phagocytosis, pinocytosis, and receptor-mediated endocytosis.
What is sensorys receptor for smell?
The sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
What are membrane proteins that bind to signals by which cells communicate?
Receptors are membrane proteins that bind to signals by which cells communicate. These receptors recognize specific signaling molecules such as hormones, neurotransmitters, and growth factors, and initiate a cellular response upon binding. Examples include G-protein coupled receptors and receptor tyrosine kinases.

Why are the cells of mucous membrane are open to virus attacks?
The cells of mucous membranes are open to virus attacks because they are not covered by a skin.
What type of membrane proteins allow cells to identify one another?
Receptor proteins.
What tissue is the lining of the stomach?
The innermost layer of the stomach is made of mucous membrane. The mucous membrane of the stomach contains simple columnar epithelium tissue, that has many exocrine cells.
What is the function of the goblet cells and which type of membrane do they occur?
Function: To secrete mucus to coat and protect the epithelia.Membrane: Mucous Membrane
The urinary tract is lined with?
Mucous membrane
Where is the receptor for cortisol found?
Receptors of protein hormones are present in plasma membrane but for steroid hormones no membrane receptors are needed as they can enter cell membrane , mobile receptors pic steroid hormones from cell membrane and carry them to nucleus .
Are the cells that line the bronchi covered with cilia to help move mucous or mucus out of the lungs?
They move 'mucus' and are cells that make up a 'mucous' membrane. Mucus is a noun, the thing that is secreted, and mucous is an adjective describing the quality of the thing that makes the mucus.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
