Frontal process of maxilla

Its anterior attachment is to the frontal process of the maxilla in front of the lacrimal groove, and its posterior attachment is the lacrimal bone.
Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus labii superioris, the orbicularis oculi, and the medial palpebral ligament.

Lacrimal sac

Crossing the lacrimal sac, it divides into two parts, upper and lower, each attached to the medial end of the corresponding tarsus.
Its superficial surface is covered by a fibrous expansion derived from the medial palpebral ligament, and its deep surface is crossed by the lacrimal part of the orbicularis oculi, which is attached to the crest on the lacrimal bone.

Tarsus (eyelids)

Crossing the lacrimal sac, it divides into two parts, upper and lower, each attached to the medial end of the corresponding tarsus. Laterally, it is attached to the tarsus of the upper and lower eyelids.
The medial angles of the two plates end at the lacrimal lake, and are attached to the frontal process of the maxilla by the medial palpebral ligament).

Orbicularis oculi muscle

It arises from the nasal part of the frontal bone, from the frontal process of the maxilla in front of the lacrimal groove, and from the anterior surface and borders of a short fibrous band, the medial palpebral ligament.

Maxilla

Its anterior attachment is to the frontal process of the maxilla in front of the lacrimal groove, and its posterior attachment is the lacrimal bone.

Aponeurosis

As the ligament crosses the lacrimal sac, a strong aponeurotic lamina is given off from its posterior surface; this expands over the sac, and is attached to the posterior lacrimal crest.

Lamina

As the ligament crosses the lacrimal sac, a strong aponeurotic lamina is given off from its posterior surface; this expands over the sac, and is attached to the posterior lacrimal crest.

Posterior lacrimal crest

posterior crest
As the ligament crosses the lacrimal sac, a strong aponeurotic lamina is given off from its posterior surface; this expands over the sac, and is attached to the posterior lacrimal crest.

Orbit (anatomy)

orbitorbitseye socket
In the adult human, the volume of the orbit is 30 ml, of which the eye occupies 6.5 ml. The orbital contents comprise the eye, the orbital and retrobulbar fascia, extraocular muscles, cranial nerves II, III, IV, V, and VI, blood vessels, fat, the lacrimal gland with its sac and nasolacrimal duct, the eyelids, medial and lateral palpebral ligaments, check ligaments, the suspensory ligament, septum, ciliary ganglion and short ciliary nerves.

Dorsal nasal artery

dorsal nasal branchnasal artery
It emerges from the orbit above the medial palpebral ligament, and, after giving a twig to the upper part of the lacrimal sac, divides into two branches.

Lateral palpebral raphe

The lateral palpebral raphé is a much weaker structure than the medial palpebral ligament.

Orbital septum

septum
Medially it is thin, and, becoming separated from the medial palpebral ligament, attaches to the lacrimal bone at its posterior crest.
