🦴The palatine bones are small paired bones located deep in the midface, forming the posterior part of the hard palate and part of the lateral walls of the nasal cavity. Though rarely discussed, they sit at an important junction between the facial skeleton and the cranial base. Each palatine bone has two main parts: the horizontal plate, which forms the back third of the hard palate, and the perpendicular plate, which contributes to the lateral wall of the nasal cavity. Through these structures they help shape the oral cavity, nasal cavity, and a small portion of the orbit. They articulate with six neighbouring bones β€” the maxilla, sphenoid, ethmoid, vomer, inferior nasal concha, and the opposite palatine bone β€” placing them at a subtle structural crossroads within the skull.πŸ’€ The palatine bones also contain the greater and lesser palatine foramina, which transmit nerves and vessels supplying the hard and soft palate via the maxillary branch of the trigeminal nerve (V2). From a craniosacral perspective, their relationships with the maxilla, sphenoid, and vomer place them within the midline architecture of the face, contributing to the organisation of the palate, nasal septum, and the deeper structures of the cranial base. Sometimes the smallest bones sit at the most interesting crossroads. ✨ At the Craniosacral Collaborative, we honour the importance of understanding anatomy in depth while maintaining a heart-centred, trauma-informed approach. β™₯️ Reel with appreciation to @anatomy.app πŸ™πŸΌ #CraniosacralTherapy #CST #palatines #HumanAnatomy #SomaticTherapy

The muscles of mastication are a group of four paired muscles responsible for movements of the mandible during chewing and speaking, all of which are innervated by the mandibular division of the Trigeminal nerve (V3). These muscles include the masseter, temporalis, medial pterygoid, and lateral pterygoid. The masseter is a strong, rectangular muscle originating from the zygomatic arch and inserting into the lateral surface of the ramus of the mandible; it elevates the mandible to close the jaw. The temporalis is a fan-shaped muscle arising from the temporal fossa and inserting into the coronoid process of the mandible; it elevates and retracts the mandible. The medial pterygoid, located on the inner surface of the mandible, originates from the pterygoid fossa and also elevates the mandible while assisting in side-to-side movements. The lateral pterygoid, with superior and inferior heads, originates from the sphenoid bone and inserts into the neck of the mandible and the articular disc of the temporomandibular joint; it helps in protrusion and depression (opening) of the jaw and plays a key role in grinding movements. Together, these muscles coordinate to produce efficient mastication. #anatomy3d #3dsurgery #physiotherapy #mbbs #muscles

Many patients with nasal congestion assume the problem is always a deviated septum. However, the lateral nasal wall is another important part of the airway. If this area collapses inward during breathing, airflow can be restricted even after septoplasty. A systematic review from the AAO-HNS journal examined surgical techniques used to support this region and improve nasal airflow. #NasalObstruction #ENTDoctor #NasalValve #Breathing #dryostent
