What type of epithelium is the conjunctiva at the fornices composed of?
Stratified columnar epithelium with goblet cells
The arterial supply of the conjunctiva is derived from which artery
(Anterior ciliary arteries)
Which nerve supplies the bulbar conjunctiva?
(from the nasociliary)
Superior palpebral conjunctiva
Superior & inferior palpebral conjunctiva
Inferior palpebral conjunctiva
Tenon's capsule lies between the conjunctiva and the
Conjunctival fornices are absent
The lateral half of the conjunctiva drains into which of the following lymph nodes?
The lateral palpebral ligament runs from the tarsal plates to which bone?
Medial palpebral ligament runs from the tarsal plates to where?
The orbital part of the upper eyelid extends from the eyebrow to the
Superior palpebral sulcus
Preganglionic parasympathetic neurons can be found in the
During convergence you contract your right medial rectus. The neurons that innervate this muscle originate at
The ipsilateral main oculomotor nucleus only
The superior oblique receives motor innervation from the
When the eye is in the primary position, the primary action produced by contraction of the lateral rectus is
Abduction of the eye
The origin of the inferior oblique can be found at the
Anteromedial orbital floor
What happens during the accommodation reflex?
The sphincter pupillae contracts
During embryology the optic nerve develops from
The neural tube
During embryology the lens placode develops from
Before going to sleep you close your eyelids. The contraction of the muscle that causes this is a result of action potentials conveyed in upper motor neurons which synapse with lower motor neurons at the
Main motor nucleus of the facial nerve
The post-ganglionic parasympathetic neurons that innervate the lacrimal gland originate in the
Venous blood from the dura mater of the braincase drains through the
Middle meningeal vein
The extradural space
Is a potential space
Provides 80% of the refractive power of the eye
An example of a structure that passes through an anterior perforation of the sclera would be
An anterior ciliary artery
The weakest part of the sclera is at the
The maxillary division of the trigeminal nerve passes between the middle cranial fossa and the pterygopalatine fossa through the
The margins of the superior orbital fissure are formed by the
Lesser and greater wings of the sphenoid bone
The optic canal pierces a process of the sphenoid bone called the
The ophthalmic division of the trigeminal nerve divides into three branches. An example of one of these three branches would be the
The upper eyelid is innervated by the supraorbital and supratrochlear nerves, and which other nerve?
You contract your muscles of mastication in order to bite into an apple. In order to contract these muscles action potentials are conveyed in neurons that originate at the
Motor nucleus of the trigeminal nerve
Whilst suffering from sinusitis you experience pain in your forehead because the mucosa of your frontal sinus is infected. The pain sensation from the frontal sinus is conveyed to the brain via the
Which muscle acts as the sphincter to close the mouth?
The tear film is wiped over the conjunctiva by the contraction of the
Drainage of tears is aided by pumping the canaliculi through contraction of the
The branch of the facial nerve that conveys secretomotor fibres to the lacrimal gland is the
Nerve of the pterygoid canal
Beta-lysin is found in which layer of the tear film?
The uveal tract is comprised of the iris, ciliary body and
The iris is thinnest in the region of the
One of the layers of the iris epithelium is composed of
The blood vessels within the choroid are organised into layers. The larger luminal vessels are located in
Ciliary processes, which secrete aqueous humour, are found within the
The supraciliaris is composed of
Loose connective tissue
Aqueous humour provides nutrients to the
With advancing age, vitreous humour undergoes
The ophthalmic artery is a branch of which artery?
The third order neurones of the visual pathway are the
Which structure is found at the junction between the first and second order neurones of the visual pathway?
The outer plexiform layer of the retina is composed of the processes of the
The left temporal visual field is detected in the
Left nasal retina
The calcarine fissure in the occipital lobe receives information directly from the
At the optic chiasm, the temporal ganglion axons
In utero, the posterior lens epithelium forms the
Primary lens fibres
The lens receives nutrients from the
An increase in intraocular pressure may result if the
Pressure within the anterior ciliary veins rises
The major arterial circle of the iris is formed by the union of the anterior ciliary arteries with which artery?
Long posterior ciliary
The afferent limb of the corneal reflex is carried in which cranial nerve?
The efferent limb of the pupillary light reflex is carried in which cranial nerve?
The apex of the maxillary sinus lies in close relationship with the
Which nerve innervates the frontal sinus?
Posterior ethmoidal air cells drain into the
Superior nasal meatus
Anterior ethmoidal cells drain into
