The objective of the present study was to evaluate the effects of insulin-like growth factor-1 (IGF-1) on the histological development of the thoracic part of the m. longus colli dorsalis (m. spinalis thoracis) in Japanese quail embryos. A single in ovo dose of recombinant human IGF-1 (rhIGF-1) (100 ng embryo) was administered through the blunt end of eggs via a single hole made with a dental d...

Acute insufficiency of the basilar artery, in the absence of organic disease, has been encountered in 20 patients. Attacks are transient and are precipitated by turning the head laterally and upwards. Two conditions are extant: (1) obliteration of vertebral artery flow by the contraction of the longus colli muscle and the scalene muscle at the level of the vertebral foramen of the sixth cervica...

The purpose of this study was to investigate the recruitment pattern of deep and superficial neck flexors evoked by three different cervical flexion exercises using muscle functional MRI. In 19 healthy participants, transverse relaxation time (T2) values were calculated for the longus colli (Lco), longus capitis (Lca), and sternocleidomastoid (SCM) at rest and following three exercises: convent...

Calcification around the cervical spine is thought to be relatively rare case, among these conditions the calcification at the longus colli muscle is called retropharyngeal tendinitis and only several cases were reported in the literature. In this disease, the three characteristic clinical features are acute severe posterior neck pain without any trigger, severely restricted range of motion, an...

Calcific tendinitis is a term used to describe radiographic evidence of calcific deposition within a tendon. This condition, also known as calcium deposition disease, has been described in the gluteus maximus, the peroneus longus tendon, the popliteus tendon, the longus colli muscle in the neck, and the tendon of the rectus femoris. However, most of the literature on calcific tendinitis relates...
