The medial palpebral ligament (tendo oculi), about 4 mm. in length and 2 mm. in breadth, is attached to the frontal process

 of the maxilla

Maxilla

The maxilla is a fusion of two bones along the palatal fissure that form the upper jaw. This is similar to the mandible , which is also a fusion of two halves at the mental symphysis. Sometimes The maxilla (plural: maxillae) is a fusion of two bones along the palatal fissure that form the upper...

 in front of the lacrimal groove

Lacrimal groove

On the nasal surface of the body of the maxilla, in front of the opening of the sinus is a deep groove, the lacrimal groove , which is converted into the nasolacrimal canal, by the lacrimal bone and inferior nasal concha; this canal opens into the inferior meatus of the nose and transmits the...

Crossing the lacrimal sac

Lacrimal sac

The lacrimal sac is the upper dilated end of the nasolacrimal duct, and is lodged in a deep groove formed by the lacrimal bone and frontal process of the maxilla...

, it divides into two parts, upper and lower, each attached to the medial end of the corresponding tarsus.

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

The lateral or orbital surface of the lacrimal bone is divided by a vertical ridge, the posterior lacrimal crest, into two parts.In front of this crest is a longitudinal groove, the lacrimal sulcus , the inner margin of which unites with the frontal process of the maxilla, and the lacrimal fossa is...
