What foramen does the trochlear nerve go through?
The trochlear nerve is also known as cranial nerve IV (CN-IV). It is the only cranial nerve that emerges dorsally from the brain, which also makes it the longest pathway. It is the smallest nerve to service the eye. CN-IV passes through superior orbital fissure, and it provides for only a motor function. It serves the superior oblique eye muscle and connects to the annular tendon. As a result, it processes brain signals to move eyes up and down and outwards. Whether due to a head injury or a complication of surgery, damage to this nerve will compromise some ability to use the superior oblique eye muscle. Without the use of the nerve, the superior oblique eye muscle will not no longer function properly. The muscle, not the trochlear nerve, physically moves the eyeball. Double vision, otherwise known as diplopia, results from problems with muscle or the nerve. Complications from these issues will result in a diminished ability to walk, especially down stairs.
Which Maxillary nerves supply to maxillary teeth?
The maxillary teeth are supplied by the following branches of the Maxillary nerve, which is itself a branch of the Trigeminal nerve:-Anterior Superior Alveolar Nerve: Upper incisors and caninesMiddle Superior Alveolar Nerve: Upper premolarsPosterior Superior Alveolar Nerve: Upper molar, and also upper premolars in the absence of the Middle SAN.
What is the function of the supra orbital foramen?
It is a passageway of the supraorbital nerve and artery
Why posterior superior alveolar nerve block does not have subjective symptoms?
Posterior superior alveolar nerve has no branches to supply areas where the patient can considerably feel the symptoms of anesthesia
What does dingling to the bottom lip mean?
The skin of bottom lip is supplied by infra orbital nerve which is branch of maxillary branch of trigeminal nerve. The nerve may be pinched somewhere in its course.
What is the function of the superior orbital fissure?
The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone. It establishes a channel of communication between the middle cranial fossa and the orbit, through which pass the oculomotor and trochlear nerves, the ophthalmic division of the trigeminal nerve, the abducens nerve, and the superior or combined ophthalmic veins.

Which are the following structures passes through the greater sciatic foramen of the llium?
pirifomis musle superior gluteal artery and vein internal pudental atery and vein superior gluteal nerve inferior gluteal atery and vein inferior gluteal nerve pudental nerve sciatic nerve poterior femoral cutanious nerve nerve to obturator internus nerve to quadratus femoris

Nerve that helps feel a toothache?
On the top (maxilla) it is the superior alveolar nerve. On the bottom (mandible) it is the inferior alveolar nerve.
Why posterior superior alveolar nerve block does not have subjective symptoms?
Posterior superior alveolar nerve has no branches to supply areas where the patient can considerably feel the symptoms of anesthesia
What is the Trochlea of the superior oblique muscle of the eye?
The Trochlea Nerve (cranial nerve 4) controls the superior oblique muscle of the eye. It turns the eye laterally and downwards.
What muscle is innervated by the trochlear nerve?
The superior oblique muscles
Acoustic neuroma most commonly arise from which part of vestibular nerve superior or inferior?
Inf vestibular nerve
What does dingling to the bottom lip mean?
The skin of bottom lip is supplied by infra orbital nerve which is branch of maxillary branch of trigeminal nerve. The nerve may be pinched somewhere in its course.
What eye movement is caused by the superior oblique?
Superior oblique is controlled by cranial nerve VI (Trochlear nerve). This muscle depresses the eye and moves it laterally. A person with damage to this cranial nerve will have difficulty looking down and to the side.
