Sinuses
Sinuses
The mucous membrane-lined cavities found in several bones surrounding the nasal cavities are called paranasal sinuses. These sinuses include the frontal, maxillary, ethmoid, and sphenoid sinuses. They help to lighten the skull, produce mucus, and regulate the resonance of the voice.
The skeletal system would not be lined with a mucous membrane. Mucous membranes are found in the respiratory, digestive, urinary, and reproductive systems to secrete mucus that helps protect and lubricate these cavities.
The nasal cavity is an example of a cavity lined with a mucous membrane. This membrane helps to humidify and filter the air we breathe, as well as trap particles and pathogens. Other cavities lined with mucous membranes include the oral cavity and the gastrointestinal tract, which also serve protective and secretory functions.
Mucous membrane
The nasal cavities are lined with mucous membranes, which produce mucus to help trap and remove dirt, pathogens, and other particles from the air we breathe. These membranes also contain cilia, tiny hair-like structures that help move the mucus and trapped particles towards the throat for removal.
The sinuses connect to the nasal cavity. They are hollow cavities located within the bones surrounding the nasal cavity and are lined with a mucous membrane.
The respiratory passages are lined with a mucous membrane called the respiratory epithelium. This epithelium helps trap foreign particles like dust and bacteria, and also contains cilia that help sweep these particles out of the respiratory system.
Yes, the rectum is lined with a mucous membrane, which is composed of epithelial tissue and secretes mucus. This membrane helps protect the underlying tissues, facilitates the passage of stool, and provides lubrication. The mucous membrane in the rectum also plays a role in sensory functions related to defecation.
Blank = Vaginal canal.
A sinus is an air-filled cavity within a bone that is lined with mucous membrane. Sinuses help to humidify and filter air as it passes through the nasal cavity.
The muscular canal lined with mucus membrane which goes between the cervix to the vulva is the vaginal canal. This is also more commonly known as the vagina, through which a penis penetrates during sexual intercourse and a baby can pass through during childbirth.
