This ligament is analogous in function (but different in exact structural detail) to the nuchal ligament found in ungulates. [8] This ligament allows dogs to carry their heads while running long distances, such as while following scent trails with their nose to the ground, without expending much energy.
The nuchal fascia is a fascia covering the autochthonous musculature of the neck as a part of the cervical fascia.It proceeds the thoracolumbar fascia to the top (cranial). ). The fascia itself is made of two parts: A superficial layer (lat.: Fascia nuchae superficialis) and a deeper layer that is located among the Trapezius muscle and that sheaths the deeper cervical musculature from dorsal s
The nuchal ligament and trapezius muscle attach to it. The inion (ἰνίον, iníon, Greek for the occipital bone) is used as a landmark in the 10-20 system in electroencephalography (EEG) recording. Extending laterally from it on either side is the superior nuchal line, and above it is the faintly marked highest nuchal line.
The supraspinous ligament connects the tips of the spinous processes from the seventh cervical vertebra to the sacrum. [1] Superior to the 7th cervical vertebra, the supraspinous ligament is continuous with the nuchal ligament.
The nuchal lines are four curved lines on the external surface of the occipital bone: The upper, often faintly marked, is named the highest nuchal line, but is sometimes referred to as the Mempin line or linea suprema, and it attaches to the epicranial aponeurosis. Below the highest nuchal line is the superior nuchal line.
The external occipital crest is part of the external surface of the squamous part of the occipital bone.It is a ridge along the midline, beginning at the external occipital protuberance and descending to the foramen magnum, that gives attachment to the nuchal ligament. [1]
nuchal ligament helps counterbalance the head; shoulders and body can rotate without rotating the head; taller body has more skin surface for evaporative heat dissipation; torso can counter-rotate to balance the rotation of the hindlimbs; shorter forearms make it easier to counterbalance hindlimbs; shorter forearms cost less to keep flexed
In human anatomy, the rhomboid minor is a small skeletal muscle of the back that connects the scapula to the vertebrae of the spinal column. [1] It arises from the nuchal ligament, and the 7th cervical and 1st thoracic vertebrae and intervening supraspinous ligaments; it inserts onto the medial border of the scapula.
