The medial palpebral ligament (medial canthal tendon) is a ligament of the face. It attaches to the frontal process of the maxilla , the lacrimal groove , and the tarsus of each eyelid . It has a superficial (anterior) and a deep (posterior) layer, with many surrounding attachments.
The elastin on the other hand is a protein that allows for flexibility. These two elements of the nuchal ligament maintain a complex balance which allows the constant weight bearing of the head along with multidirectional movement without damaging the durability of the ligament through over-use/stretching.

From these attachments the fibers are directed upward, and join the galea aponeurotica below the coronal suture. The medial margins of the frontalis muscles are joined together for some distance above the root of the nose ; but between the occipitales there is a considerable, though variable, interval, occupied by the galea aponeurotica .
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
The mastoid process serves for the attachment of the sternocleidomastoid, the posterior belly of the digastric muscle, splenius capitis, and longissimus capitis. On the medial side of the process is a deep groove, the mastoid notch, for the attachment of the digastric muscle ; medial to this is a shallow furrow, the occipital groove , which ...
A tendon is a tough, flexible band of fibrous connective tissue that connects muscles to bones. [12] The extra-cellular connective tissue between muscle fibers binds to tendons at the distal and proximal ends, and the tendon binds to the periosteum of individual bones at the muscle's origin and insertion. As muscles contract, tendons transmit ...
The bicipital groove separates the greater tubercle from the lesser tubercle. [1] It is usually around 8 cm long and 1 cm wide in adults. [1] The groove lodges the long tendon of the biceps brachii muscle, positioned between the tendon of the pectoralis major muscle on the lateral lip and the tendon of the teres major muscle on the medial lip.
