Study Notes
Anatomy of the Respiratory System
- Four paranasal sinuses: frontal, maxillary, ethmoidal, sphenoidal. One NOT included may be the nasosinal.
- Functions of the nose include filtering, moistening, and warming air, as well as olfaction; a function NOT included may involve sound production.
Pharynx Divisions
- The pharynx has three anatomical divisions: nasopharynx (behind the nose), oropharynx (behind the mouth), laryngopharynx.
- NOT a function of the pharynx might be sound resonance.
Laryngeal Anatomy
- Epiglottis consists of elastic cartilage.
- Larynx muscles grouped into intrinsic (control vocal cords) and extrinsic (support position).
Vocal System
- The vestibular folds (false vocal cords) prevent foreign objects from entering the larynx and stabilize the airway.
- The opening between the true vocal cords is called the glottis.
- Ciliated mucous membrane in the larynx traps debris and pathogens, keeping the airways clear.
Functions of the Nose and Nasal Cavity
- The external nose comprised of bone and cartilage also contains sebaceous glands.
- The cribriform plate of the ethmoid bone separates the nasal cavity from the cranial cavity.
- The olfactory nerve is responsible for the sense of smell.
- The respiratory region of the nasal cavity has a mucosa with hairs, sebaceous glands, and sweat glands for filtration and moisture retention.
- Goblet cells in the nasal cavity produce mucus to trap particles.
- The nasal septum divides the nasal cavity into left and right parts.
- Function of paranasal sinuses includes reducing skull weight and enhancing voice resonance.
- Air enters the respiratory portion at the choanae.
Nasal Cavity Functionality
- Cilia in the nasal cavity propel mucus towards the throat for swallowing or expulsion.
- Nosebleeds often arise from vascular structures in the nasal cavity, particularly the kiesselbach plexus.
- The nasal cavity is also separated from the cranial cavity by the ethmoid bone.
Oropharyngeal Anatomy
- Oropharynx contains palatine tonsils.
- The majority of the larynx is formed by thyroid cartilage.
Additional Laryngeal Functions
- Vestibular folds main function includes protecting the airway and providing support during breathing.
- Ciliated mucous membrane in the larynx serves to trap dust and pathogens, keeping the airway clean.
Recap of Paranasal Sinuses
- Notably, other sinuses might include accessory or lesser-known cavities, which are not classified as primary sinuses.
