The Canal of the Cervix (canalis cervicis uteri) is somewhat fusiform, flattened from before backward, and broader at the middle than at either extremity. ❋ Unknown (1918)
The Spinalis cervicis (Spinalis colli) is an inconstant muscle, which arises from the lower part of the ligamentum nuchæ, the spinous process of the seventh cervical, and sometimes from the spinous processes of the first and second thoracic vertebræ, and is inserted into the spinous process of the axis, and occasionally into the spinous processes of the two vertebræ below it. ❋ Unknown (1918)
The Iliocostalis cervicis (Cervicalis ascendens) arises from the angles of the third, fourth, fifth, and sixth ribs, and is inserted into the posterior tubercles of the transverse processes of the fourth, fifth, and sixth cervical vertebræ. ❋ Unknown (1918)
Those of the lower three nerves are small, and end in the Semispinales cervicis and capitis, Multifidus, and Interspinales. ❋ Unknown (1918)
The Iliocostales cervicis, taking their fixed points from the cervical vertebræ, elevate those ribs to which they are attached; taking their fixed points from the ribs, both muscles help to extend the neck; while one muscle bends the neck to its own side. ❋ Unknown (1918)
The Longissimus capitis (Trachelomastoid muscle) lies medial to the Longissimus cervicis, between it and the Semispinalis capitis. ❋ Unknown (1918)
The supravaginal portion (portio supravaginalis [cervicis]) is separated in front from the bladder by fibrous tissue (parametrium), which extends also on to its sides and lateralward between the layers of the broad ligaments. ❋ Unknown (1918)
The chief communications outside the skull take place between the superior and inferior thyroid arteries, and the profunda cervicis and ramus descendens of the occipital; the vertebral takes the place of the internal carotid within the cranium. ❋ Unknown (1918)
When both Longissimi cervicis act from below, they bend the neck backward. ❋ Unknown (1918)
The Semispinalis cervicis (Semispinalis colli), thicker than the preceding, arises by a series of tendinous and fleshy fibers from the transverse processes of the upper five or six thoracic vertebræ, and is inserted into the cervical spinous processes, from the axis to the fifth inclusive. ❋ Unknown (1918)
The lateral branches of the lower five nerves supply the Iliocostalis cervicis, Longissimus cervicis, and Longissimus capitis. ❋ Unknown (1918)
The medial branches of the fourth and fifth run between the Semispinales cervicis and capitis, and, having reached the spinous processes, pierce the Splenius and Trapezius to end in the skin (Fig. 801). ❋ Unknown (1918)
The Longissimus cervicis (Transversalis cervicis), situated medial to the Longissimus dorsi, arises by long thin tendons from the summits of the transverse processes of the upper four or five thoracic vertebræ, and is inserted by similar tendons into the posterior tubercles of the transverse processes of the cervical vertebræ from the second to the sixth inclusive. ❋ Unknown (1918)
Extension is produced by the intrinsic muscles of the back, assisted in the neck by the Splenius, Semispinales dorsi and cervicis, and the Multifidus. ❋ Unknown (1918)
The Spinalis capitis (Biventer cervicis) is usually inseparably connected with the Semispinalis capitis (see below). ❋ Unknown (1918)
The medial part, usually more or less distinct from the remainder of the muscle, is frequently termed the Spinalis capitis; it is also named the Biventer cervicis since it is traversed by an imperfect tendinous inscription. ❋ Unknown (1918)
The Descending Branch (ramus descendens; arteria princeps cervicis) (Fig. 513), the largest branch of the occipital, descends on the back of the neck, and divides into a superficial and deep portion. ❋ Unknown (1918)
The Splenius cervicis (Splenius colli) (Fig. 409) arises by a narrow tendinous band from the spinous processes of the third to the sixth thoracic vertebræ; it is inserted, by tendinous fasciculi, into the posterior tubercles of the transverse processes of the upper two or three cervical vertebræ. ❋ Unknown (1918)
The Semispinalis capitis (Complexus) is situated at the upper and back part of the neck, beneath the Splenius, and medial to the Longissimus cervicis and capitis. ❋ Unknown (1918)
Its medial branch runs between the Semispinalis capitis and cervicis, and, piercing the Splenius and Trapezius, ends in the skin. ❋ Unknown (1918)
