Deglutition
Deglutitionrishidk91This document provides an overview of deglutition (swallowing), including the physiologic events, neural control, and patterns of swallowing. It describes the preparatory, oral, pharyngeal, and esophageal stages of normal mature swallowing. Abnormal swallowing patterns like simple and complex tongue thrust are discussed. Conditions that can cause defective swallowing include paralysis of nerves involved in swallowing from issues like encephalitis. The risks of paralysis under deep anesthesia are also noted.
Develpoment of face and tongue
Develpoment of face and tongueDr. Roshni MauryaThe document discusses prenatal development of the face and palate from the 3rd to 12th week of gestation. It describes how the facial prominences merge to form structures like the nose, lips, and cheeks. It also explains palate formation, including the development of the primary and secondary palate, elevation of the palatal shelves, and their fusion to complete the separation of the oral and nasal cavities.
Suboccipital triangle
Suboccipital triangleChitransha031. The suboccipital triangle is a triangular space located deep in the suboccipital region on each side of the neck.
2. It is bounded by four suboccipital muscles and contains the suboccipital plexus of veins, the dorsal ramus of C1, and the third part of the vertebral artery.
3. The suboccipital triangle provides an important surgical approach for procedures such as cisternal puncture and removal of posterior fossa tumors.
Mastication, degluttition and speech
Mastication, degluttition and speechSakshi Mudgil1) Mastication involves the chewing and grinding of food using the teeth and muscles of mastication. As food is broken down, it is mixed with saliva and prepared for swallowing.
2) The muscles of mastication work in a coordinated manner through opening and closing strokes to crush and grind food between the teeth. Sensory feedback and reflexes help coordinate this chewing cycle.
3) After sufficient mastication, the food is swallowed through a coordinated process of deglutition involving the oral, pharyngeal, and esophageal phases to transport the food bolus to the stomach for further digestion.

Scalene
ScaleneMD RahmanThe scalene muscles are a group of three pairs of muscles in the lateral neck. They originate on the cervical vertebrae and insert on the first and second ribs. The scalenes function to elevate the ribs and flex/rotate the neck. Scalene trigger points can refer pain to various areas and are involved in conditions like thoracic outlet syndrome. Scalene muscles can be tested by having the individual flex their head against resistance while rotated. Treatment involves eliminating causes, massage, stretching targeted parts of the scalene muscles on both sides of the neck, and strengthening exercises.

Temporomandibular Joint (TMJ)
Temporomandibular Joint (TMJ)HeatherSeghiThe temporomandibular joint (TMJ) connects the temporal bone of the skull to the mandible. It contains an articular disc that separates the joint into upper and lower compartments. The condyle of the mandible articulates with the mandibular fossa in the lower compartment and glides forward in the upper compartment. The articular disc allows for this movement and is innervated by the auriculotemporal and masseteric nerves. Disorders of the TMJ can cause sounds, locking, or pain and are sometimes caused by bruxism or arthritis.

It discusses the embryology, functions, muscles, blood supply, innervation and clinical considerations of the tongue. It also discusses the anatomy of the hard palate, soft palate, muscles and blood supply of the palate. Finally, it summarizes the three phases of deglutition - the oral, pharyngeal and esophageal phases.
hard and soft palate
hard and soft palatemadhushreepatil5The document discusses the anatomy, development, and prosthodontic considerations of the hard and soft palate. It begins with an introduction to the palate and its two parts: the anterior hard palate and posterior soft palate. It then covers the embryological development of the palate and anatomical structures of both parts such as bones, muscles, nerves and vessels. Developmental anomalies including various cleft classifications are discussed. Finally, the document addresses prosthodontic factors related to different palate types and tissues that are important to consider for denture construction and retention.
3.NASO-RESPIRATORY OBSTRUCTION.ppt
3.NASO-RESPIRATORY OBSTRUCTION.pptIRONMASTER96This document discusses the role of naso-respiratory obstruction in malocclusion etiology. It covers anatomy of the nose, pharynx and velum. Nasal respiratory inadequacy can lead to mouth breathing and affect facial development. Adenoid enlargement is one cause and may result in the "adenoid facies" characterized by a long vertical face. While earlier theories linked mouth breathing to facial changes, more recent studies question this relationship. Cephalometric analysis can evaluate the upper airway but has limitations due to its 2D representation of 3D structures.
soft palate
soft palateHamzeh AlBattikhiThe soft palate contains five muscles that are important for swallowing and breathing. The muscles are the tensor veli palatini, levator veli palatini, palatoglossus, palatopharyngeus, and musculus uvulae. Each muscle has a specific origin, insertion point, and action. For example, the levator veli palatini originates from the base of the skull and curves downward and forward to enter the palate, contracting to lift the soft palate upwards and backwards during swallowing. The muscles receive their nerve supply from either the trigeminal or accessory cranial nerves and are supplied by arteries including the facial and maxillary arteries.

Glossopharyngeal nerve & its pathology ppt
Glossopharyngeal nerve & its pathology pptD Venkatesh KumarThe glossopharyngeal nerve is the ninth cranial nerve. It is a mixed nerve that originates in the medulla oblongata and exits through the jugular foramen. It carries both sensory and motor fibers and innervates the middle ear, tonsils, back of the tongue, pharynx, and the stylopharyngeus muscle. Damage to the glossopharyngeal nerve can result in loss of sensation in these areas as well as difficulties swallowing and reduced salivation. Glossopharyngeal neuralgia is a condition characterized by severe pain in the throat and ear caused by compression of the nerve.
