What is psuedostratified columnar epithelium?
looks as if it is more than one layer, but not all cells reach free surfaceoften has goblet cells and ciliathe function is secreting and moving mucousfound in the repiratory tract from nose to bronchi, and some parts of the male reproductive tract.
Insects have olfactory sensors on their?
i know some insects have olfactory sensors on their feet idont know if all of them do tho
What part of the body secretes mucus to trap and move dust and debris?
Goblet cells. They are located in the epithelium of many organs along with other cells. But, they are more prominent in the intestinal and the respiratory tracts.
What covers the esophagus?
The epiglottis covers the esophagus. The epiglottis is a small flap that covers the epiglottis when breathing and covers the trachea, or windpipe, when you are eating to prevent food from entering the lungs.
The tissue that lines all internal surfaces is?
epithelium
How do people smell food?
A specialized smell receptor is situated In the roof of the nasal canal,called Olfactory mucosa. the olfactory epithelium is innervated by the olfactory(1st cranial)nerve and some branches of the 5th nerve.Olfactory epithelium contains three kinds of cells,namely olfactory receptor cells,supporting cells and basal cells.Olfactory receptor cells are sensory hair cells,sensitive to all kind of cells.Their axons terminally join the olfactory nerve. Supporting cells are mucus-secreting columnar cells. Basal cells are the stem cells from which new receptor cells are formed.Olfaction,just like taste,is a chemical sense. The molecules of the odorous substances reach the nasal canal along with the inspired air. Here, they dissolve in the mucus secretion and then attach to the receptor cells. This stimulates the receptor cells and they generate olfactory impulses. Olfactory nerves transmit these impulses to the olfactory center in the temporal lobe of the cerebrum(known as the olfactory cortex)
What is in charge of your olfactory system?
The mechanism of the olfactory system can be divided into a peripheral one, sensing an external stimulus and encoding it as an electric signal in neurons, and a central one, where all signals are integrated and processed in the central nervous system. The peripheral olfactory system receptors are connected to bipolar olfactory receptor neurons in the olfactory epithelium. Fot the central olfactory system, axons from the olfactory sensory neurons converge in the olfactory bulb.
What best describes covering and lining epithelium?
Covering epithelium is tissue which covers and lines all of the bodies surfaces and cavities inside and out for example the skin.
Nerve fibers of the olfactory tracts lead to?
The olfactory tract is split into medial and lateral. Their projections are to 5 different areas of the brain- anterior olfactory nucleus, olfactory tubercle, Piriform cortex, Amygdala, Entorhinal cortex The lateral tract originates from the olfactory epithelium separates into mitral cells and tuft cells. mitral cells synapses onto all 5 of the regions to ultimately synapse onto the orbitofrontal cortex via the thalamus or the frontal cortex. tufted cells on the other hand only synapse onto the anterior olfactory nucleus and the olfactory tubercle The medial or vomeronasal tract projects to mitral cells that synapse only to the Amygdala
What would happen if the digestive tract was lined with stratifed squamous epithelium instad of simple columnar epithelium?
Through stratified squamous epithelium absorption will be very poor and person will die of starvation.Malabsorption could occur if the digestive tract were lined with stratified squamous epithelium instead of simple columnar eqithelium.
What is the basis of biologist to classify a specific epithelial tissue?
Epithelia are tissues consisting of closely apposed cells without intervening intercellular substances. Epithelia are avascular, but all epithelia "grow" on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.

What is the function of gland cells?
They are sheets of cells [Epithelial tissue or epithelium] that covers the body surface or lines a body cavity. They form bounderies between different environments and nearly all substances received or given off by the body must pass through some sort of epithelium.
Insects have olfactory sensors on their?

How does the epithelia of esophagus relate to its function?
The epithelium is non-keratinized stratified squamous epithelium with scattered mucus glands. Let's go through each of these characteristics: Stratified - Many cells so that friction from esophageal objects does not scrape off deep cells. Squamous - Flat cells that allow sloughing off and closer packing Mucus Glands - Lubricate the passage of food down esophagus All these things help the function of esophagus to transfer food from mouth to stomach!
What part of the body secretes mucus to trap and move dust and debris?
Goblet cells. They are located in the epithelium of many organs along with other cells. But, they are more prominent in the intestinal and the respiratory tracts.
What covers the esophagus?
The epiglottis covers the esophagus. The epiglottis is a small flap that covers the epiglottis when breathing and covers the trachea, or windpipe, when you are eating to prevent food from entering the lungs.
