Study Notes
Nasal and Oral Cavities
- The oral cavity is a primary area for food intake and digestion.
- Contains important structures such as the tongue and teeth.
Pharynx Composition and Muscle Type
- The pharynx is composed mainly of striated muscle.
- Striated muscles allow for voluntary control during swallowing.
Neural Innervation
- The glossopharyngeal nerve innervates the oropharynx, playing a critical role in sensation and motor control.
- Pharyngeal muscles are primarily innervated by the vagus nerve, except for the stylopharyngeus muscle, which is innervated by the glossopharyngeal nerve.
Tonsils and their Functions
- Tonsils are primarily made of lymphoid tissue, crucial for immune response.
- The primary function of tonsils is to produce white blood cells to fight infections.
Location of Pharyngeal Structures
- The laryngopharynx is located posterior and lateral to the larynx, serving as a passage for air and food.
- Pharyngeal tonsils are found in the nasopharynx, playing a role in immune defense.
Specified Tonsils
- Tubal tonsils are found along the auditory tube, while lingual tonsils are located on the tongue.
Pharyngeal Functionality
- The pharynx connects the nasal cavity and mouth to the esophagus, crucial for respiration and digestion.
- Longitudinal muscles in the pharynx assist in elevating it during swallowing.
Salpingopharyngeal Muscle
- The salpingopharyngeus muscle runs from the auditory tube to the pharynx, aiding in the swallowing mechanism.
Teeth Structure and Functions
- The maxillary row represents the upper set of teeth, essential for biting and chewing.
- Incisors are flat and used primarily for biting and cutting, while canines facilitate piercing and tearing.
Types of Papillae on the Tongue
- Fungiform papillae are mushroom-shaped and house numerous taste buds, located on the anterior part of the tongue.
- Foliate papillae, found on the posterior part, contain taste buds but are less prominent in adults.
- Circumvallate papillae, located at the terminal sulcus, are important for taste sensation and have a territorial interaction with cranial nerves.
Directional Dental Terms
- 'Mesial' refers to the direction towards the midline or incisors, while 'distal' indicates the direction towards the molars.
- 'Buccal' refers to the surfaces of teeth that face the cheeks or lips.
Additional Anatomical Features
- The retropharyngeal space is located between the alar fascia and the buccopharyngeal fascia, important for potential pathways of infection.
- The Danger Space extends down to the diaphragm, posing risks for medical conditions if infected.
Muscle Innervation Principles
- Sternal's Law indicates tensor muscles are innervated by the trigeminal nerve, with many palate muscles innervated by the vagus nerve.
- Muscles with 'gloss' in their names are typically innervated by the hypoglossal nerve, ensuring proper tongue movement and function.
