The mandibulo-stylohyoid ligament (tractus angularis).

The authors of the present study were able to expose the tractus angularis (the mandibulo-stylohyoid ligament), which was consistently found as a large ligament extending from the angle of the mandible to the stylohyoid ligament, with prolongations in the direction of the stylohyoid m. and the posterior belly of the digastric. The ligament forms part of the structures which separate the submandibular gland from the parotid gland. We believe that this ligament should be included in anatomy textbooks, and we affirm our perception of these structures as potentially important for clinical and surgical anatomy.

A comparative study of the foramen transversarium of the sixth and seventh cervical vertebrae.

The purpose of our study was to evaluate the individual variations of the foramen transversarium of the seventh cervical vertebra. This foramen sometimes has the same dimensions as the foramina of the other cervical vertebrae, but it can also be smaller, or absent. In cases where a foramen is present in the seventh cervical vertebra, vascular or nerve structures (or both) can be occasionally observed within. When the transverse foramina are found to contain none of the above structures, what then is to be found within this space? According to our results, the transverse foramina of the seventh cervical vertebra almost always contains vascular and nerve branches as well as fibrous and adipose tissues. This report concerns the results of the macroscopic and microscopic studies concerning the contents of the transverse foramina of the sixth and seventh cervical vertebrae. The comparative study was completed at the Department of Anatomy of the Faculty of Medicine, University Laval.

A comparative study of the spaces between the metacarpal and metatarsal heads.

The study of the spaces between the metacarpal heads on 23 cadavers, raises the question of the existence of bursae at this level. This is in line with recent studies suggesting that such bursae are present at this level in the foot. Careful dissection and histological studies revealed characteristics compatible with both of the following hypotheses: either the existence of bursae not described until now in anatomy text-books, or spaces limited by a cul-de-sac of the aponeuroses of the hand in the 2nd, 3rd and 4th digits. Tissue analyses that could determine more specifically the nature of the limiting membrane of these spaces, as well as pathological studies demonstrating the occurrence of common anomalies of bursae in these spaces, are required in order to conclude definitively the nature of the spaces between the metacarpal heads. The gross anatomical and histological characteristics of the spaces between the metacarpal and metatarsal heads and of their limiting membranes were compared and found to be analogous in our series.

[The inter-metacarpo-phalangeal spaces].

The study of the inter-metacarpophalangeal spaces on 20 human bodies raises the question of the existence of bursae at this level, in line with recent studies (BOSSEY, MIDY) suggesting that such bursae are present at the level of the foot. Careful dissection and histological studies revealed characteristics compatible with both of the following hypotheses: either there are bursae not described until now in anatomy textbooks, or these are virtual spaces limited by a cul-de-sac of the aponeuroses of the hand in the 2nd, 3rd and 4th spaces. Tissue analysis that could determine more specifically the nature of the limiting membrane of these spaces, as well as pathological studies demonstrating the occurrence of common anomalies of bursae in these spaces, are required in order to conclude definitively on the nature of the inter-metecarpophalangeal spaces.

[Contents of the transversal foramen of the seventh cervical vertebra].

The purpose of our study was to evaluate the individual variations of the foramen sometimes has the same dimensions as the foramen of the other cervical vertebrae, but it can also be smaller, or absent. In cases where the foramen is present in the seventh cervical vertebra, vascular or nerve structures (or both) can be occasionally observed within. When the transverse foramina are found to contain none of the above structures, what then is to be found within this space? According to our results, the transverse foramina of the seventh cervical vertebra almost universally contain vascular and nerve branches as well as fibrous and adipose tissue. This report concerns the results of the macroscopic and microscopic studies concerning the contents of the transverse foramina of the seventh cervical vertebra.
