What type of tissue is found in the nasal cavity?
The respiratory segment comprises most of each nasal cavity, and is lined with ciliated pseudostratified columnar epithelium (also called respiratory epithelium). The conchae, or turbinates, are located in this region.
What could a mass in the sinus cavity be?
A paranasal sinus tumor is a cancer that has grown inside your sinuses, the open spaces behind your nose. This tumor can begin in the cells of the membranes, bones, or nerves that line the area. You might not know or even suspect that a tumor is growing until it spreads.
What is the histology of the nasal cavity?
Entering the nares, or nostrils, the nasal vestibule is lined by keratinized stratified squamous epithelium – a continuation of the cutaneous lining from the external nose. It is also equipped with modified hairs, called vibrissae that filter out larger particles from inspired air.
What type of tissue forms the lining of the nasal cavities quizlet?
Stratified epithelium is found lining body cavities. Simple epithelium is associated with filtration.
What are conchae?
The conchae are structures made of bone inside of your nose. They help control the airflow into your nose. They also clean and warm air that you’ve inhaled so that it’s ready to go to your lungs for respiration. Respiration is the process of breathing in and out.
How do you know if you have a nasal tumor?
Signs and symptoms of nasal and paranasal tumors can include: Difficulty breathing through your nose. Loss of the sense of smell. Nosebleeds.
What tissue forms articular and costal cartilage?
Hyaline cartilage is the most widespread cartilage type and, in adults, it forms the articular surfaces of long bones, the rib tips, the rings of the trachea, and parts of the skull. This type of cartilage is predominately collagen (yet with few collagen fibers), and its name refers to its glassy appearance.
What is the most common type of tissue?
Connective tissue. Connective tissue is the most abundant tissue type in the body. In general, connective tissue consists of cells and an extracellular matrix. The extracellular matrix is made up of a ground substance and protein fibers.
What are turbinates?
Turbinates are bony structures inside the nose, covered by soft tissue (mucosa). They regulate airflow and warm and humidify the air you inhale. They do this by swelling up with increased blood flow.
What are the 3 nasal conchae?
nasal concha, also called Turbinate, or Turbinal, any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities. The components of the nasal conchae are the inferior, medial, superior, and supreme turbinates.
