- 1The external nose includes:Nasal bone and (hyaline) cartilage
- 2Another name for nostrils:Nares - has an Anterior opening, separated via septum
- 3The nasal cavity includes• Superior nasal concha
• Middle nasal concha
• Inferior nasal concha - 4What are Choanae?• Posterior nasal apertures
• Opens into the nasopharynx
- 5What type of epithelium lines the Nasal Vestibule?Stratified Squamous = Resistant to mechanical stresses
- 6What type of epithelium lines the Nasal Cavity?Pseudostratified ciliated columnar (propel mucus back to the throat)
& Goblet cells that secret mucus. - 7Define Nasal Conchascroll-like (turbinate) bones in the sides of the nasal cavity
- 8Define Meatusa passage or opening leading to the interior of the body.
- 9The region of the pharynx extends from?Choanae to the Larynx (voice box)
- 10What are the three regions of the Pharynx?• Nasopharynx:
- Nose to soft-palate
- Lined with Respiratory epithelium
- Continuous with nasal cavity
• Oropharynx
- Soft palate to tongue
• Laryngopharynx
- Epiglottis to entrance of larynx and oesophagus - 11The region of the Larynx extends from?Tongue to the Trachea (& is anterior to oesophagus)
- 12What is the function of the pharynx?The Muscular tube is designed for the passage of air and food
- 13What are two main functions of the Larynx?1. Prevents ingested substances from entering the lower respiratory system during deglutition (swallowing).
2. Produces sound for speech. - 14What are the 4 main Laryngeal cartilages?- Thyroid cartilage
- Arytenoid cartilage
- Cricoid cartilage
- Tracheal cartilage
- 15Another name for Adam's apple?Laryngeal prominence
- 16Define Rima Glottidisis the opening between the true vocal cords and the arytenoid cartilages of the larynx
- 17What are the main skeletal features of the Thorax?• Thoracic vertebrae, ribs, costal cartilages & sternum.
- 18What are the joints of the thorax?• Costovertebral, costotransverse, costochondral & chondrosternal Joints.
- 19What are the Muscles of the thorax?• Diaphragm, intercostal muscles & accessory muscles of ventilation.
- 20What are the main Cavities of the thorax?• Thoracic inlet, mediastinum, right & left thoracic cavities.
- 21How many ribs are there?12 all up
- True ribs (1-7)
- False ribs (8-10)
- Floating ribs (11, 12) - 22What are the two intercostal muscles?- External intercostal muscles
- Internal intercostal muscles
- 23Where the trachea diverges into the left and right (primary) bronchi is termedCarina (sternal angle)
- 24The primary bronchi branches into the• Lobar (secondary) bronchi (3R and 2L)
• Segmental (tertiary) bronchi (10R and 8L)
• Bronchioles
• Alveoli - 25The three surfaces of the lungs are?1. Costal (lateral)
2. Mediastinal
3. Diaphragmatic surface (i.e. Base).
- 26How many lobes on the left and right lungs?•3 on the right
•2 on the left - 27How many fissures on the left and right lungs?•2 on the right
•1 on the left - 28What are some features of the Hilum?•Located on the Mediastinal surface
• ‘gateway’ into lung for bronchi and pulmonary vessels - 29Name the fissures of the lungsRight Lung:
- Horizontal fissure
- Right oblique fissure
Left Lung:
- Left oblique fissure - 30What are the 3 main channels entrances passing through the hilum of the lungs?- R/L primary bronchus (Posterior-superior most structure)
- Pulmonary artery (Anterior-superior most structure)
- Pulmonary vein (Anterior-inferior
most structures) - 31Define PleuraA delicate membrane that encloses the lungs
