Sphenoid bone anatomy : Part- 4 ( Lesser wing & Pterygoid process )

🎥 Sphenoid Bone Anatomy: Lesser Wing & Pterygoid Process Explained! Welcome to our detailed anatomy breakdown! In this video, we explore two critical parts of the sphenoid bone — the lesser wing and the pterygoid process — essential for understanding cranial and facial architecture. 🔍 What's Inside: 🦴 Lesser Wing of the Sphenoid: Thin, triangular bony plates projecting laterally from the sphenoid body Forms the posterior part of the roof of the orbit and part of the superior orbital fissure Provides attachment for the tentorium cerebelli Contains the optic canal, transmitting the optic nerve (CN II) and ophthalmic artery 🦴 Pterygoid Process: Projects downward from the sphenoid bone's junction between the body and greater wing Divided into two plates: Medial pterygoid plate: Ends in the pterygoid hamulus, a pulley-like projection guiding the tendon of the tensor veli palatini., contributes to the lateral wall of the nasal cavity Lateral pterygoid plate: provides attachment for pterygoid muscles important in mastication Forms part of the pterygopalatine fossa and infratemporal fossa Intervening Pterygoid Fossa: Lies between the medial and lateral plates. Contains the medial pterygoid muscle 🎯 Clinical Relevance: Crucial landmarks for neurosurgery and maxillofacial procedures Involved in the transmission of key cranial nerves and vessels 📚 Ideal for: Medical & dental students Anatomy learners Healthcare professionals prepping for exams 🔔 🔔 Don’t forget to LIKE, SUBSCRIBE, and SHARE if you found this content helpful and turn on notifications for more high-yield anatomy videos! #SphenoidBone #Neuroanatomy #AnatomyLecture #MedicalEducation #PterygoidProcess #LesserWing #AnatomyMadeEasy #sphenoid #SphenoidBone #AnatomyLecture #MedicalEducation #HeadAndNeckAnatomy #CranialAnatomy #PterygoidProcess #LesserWing #Neuroanatomy #SkullAnatomy #AnatomyTutorial
