How many bones contribute to the framework of each Orbit of Eye?
Maxilla, Zygomatic, Frontal, Ethmoid, Lacrimal, Sphenoid and Palatine Bones contribute to form Orbit of Eye.
Superior Orbital Fissure is present in?
Postero-Superior portion of Auricle is Supplied by?
Great Auricular Nerve supplies anterior and posterior inferior portion, Facial Nerve and Vagus Nerve supplies the deeper parts of auricle, and Auriculotmeproal from Mandibular supplies anterior superior portion.
Sensory innervation to the Mucuous membrane on inner surface of Tympanic Membrane?
All others carry fibers from External Surface.
Complete Ptosis is due to damage of?
Damage to Orbicularis Occuli causes an inability to close the eyelid, and damage to Superior Tarsal Muscle causes PARTIAL PTOSIS, like in Horner’s Syndrome.
Epithelium of conjunctiva?
The conjunctival epithelium is a non-keratinized, stratified columnar epithelium that lines the inside of the eyelids and covers the sclera. The conjunctiva contains goblet cells that secrete mucin, which generates the moisture that covers the surface of the eye and allows the eyelids to open and close easily.
Vertebral level of Hyoid bone?
The hyoid bone is a 'U' shaped structure located in the anterior neck. It lies at the base of the mandible (approximately C3), where it acts as a site of attachment for the anterior neck.
Infection of Pretracheal Space spread to?
The pretracheal space descends into the anterior mediastinum and most often is involved in mediastinitis complicating surgery of the Thyroid or Trachea.
Largest Parasympathetic Ganglia in Head is?
The pterygopalatine ganglion (of Meckel), the largest of the parasympathetic ganglia associated with the branches of the maxillary nerve, is deeply placed in the pterygopalatine fossa, close to the sphenopalatine foramen.
In which wall of middle ear, pyramidal eminence is present?
Pyramidal eminence: a hollow, cone-shaped prominence in the posterior wall of the tympanic cavity.
Orbital Septum is formed by?
The orbital septum is an extension of fibrous tissue continuous with the periosteum, extending from the orbital rim to lids.
Which Muscle Tendon passes through Fibrocartilaginous Pulley?
The tendon of the superior oblique muscle passes through a fibrocartilaginous pulley (trochlea) attached to the Frontal Bone.
Nerve supply of Occipato-Frontalis Muscle is?
Frontal belly: Temporal branches of facial nerve (CN VII) Occipital belly: Posterior auricular nerve (branch of facial nerve (CN VII).
Muscle supplied by Superior Root of Ansa Cervicalis?
Cerumenous Glands are?
Modified sweat glands in the external ear, called ceruminous glands produce a waxy lubricating secretion.
Root value of greater Occipital Nerve is?
Triangle between Superior Belly of Omohyoid and Posterior Belly of digastric Muscle is?
Carotid Triangle The carotid triangle of the neck has the following boundaries: Superior – posterior belly of the digastric muscle. Lateral – medial border of the sternocleidomastoid muscle. Inferior – superior belly of the omohyoid muscle.
Person is unable to Lacrimate, What is damaged in Middle Cranial Fossa?
Greater Petrosal Nerve carries Preganglionic Parasympathetic Fibers and passes through Middle Cranial Fossa.
Blood vessels and nerves supplying the Scalp are present in?
Blood vessels and sensory nerves traverse the scalp in a centripetal fashion through the subcutaneous connective tissue layer.
Nerve supply to Geniohyoid Muscle?
The geniohyoid muscle is innervated by fibres from the first cervical nerve travelling alongside the hypoglossal nerve.
Artery arising from Posterior Surface of External Carotid Artery?
Infection of Scalp spread through which layer?
Loose Areolar Tissue Layer sometimes referred to as the "danger zone" because of the ease by which infectious agents can spread through it to emissary veins which then drain into the cranium.
Only Muscle Supplied by Glossopharyngeal Nerve?
The Stylopharyngeus is the only muscle in the pharynx innervated by the glossopharyngeal nerve (CN IX) through branchial motor fibers that originate in the rostral part of the nucleus ambiguus.
Nerve of Pterygoid Canal is formed by?
The nerve of the pterygoid canal (Vidian nerve) is formed by the junction of the greater petrosal nerve and deep petrosal nerve, which passes from the foramen lacerum to the pterygopalatine fossa through the pterygoid canal.
Nasolacrimal Duct is derived from?
