The supratrochlear nerve passes medially [3] above the trochlea of the superior oblique muscle. [2] [3] It then travels anteriorly above the levator palpebrae superioris muscle. [1] It exits the orbit through the supratrochlear notch or foramen. [3] It then ascends onto the forehead beneath the corrugator supercilii muscle and frontalis muscle ...
The clinical consequences of weakness in the superior oblique (caused, for example, by fourth nerve palsies) are discussed below. This summary of the superior oblique muscle describes its most important functions. However, it is an oversimplification of the actual situation.
Involvement of the cranial nerves that pass through the superior orbital fissure may lead to diplopia, paralysis of extraocular muscles, exophthalmos, and ptosis. Blindness or loss of vision indicates involvement of the orbital apex, which is more serious, requiring urgent surgical intervention.
The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
Innervation is the connection of nerves to the scalp: the sensory and motor nerves innervating the scalp. The scalp is innervated by the following: Supratrochlear nerve and the supraorbital nerve from the ophthalmic division of the trigeminal nerve; Greater occipital nerve (C2) posteriorly up to the vertex; Lesser occipital nerve (C2) behind ...
The supratrochlear artery (or frontal artery) is one of the terminal branches of the ophthalmic artery. It arises within the orbit. [1] [2] It exits the orbit alongside the supratrochlear nerve. It contributes arterial supply to the skin, muscles and pericranium of the forehead. [3]
The frontalis muscle is supplied by the facial nerve [4] and receives blood from the supraorbital and supratrochlear arteries. Structure
